IQ23x
Data Sheet
Functionality
The IQ Controller’s functionality can be divided into three sections, strategy, firmware, and hardware.
Strategy
The strategy processes inputs according to a set of instructions
and then outputs signals which can be used to control plant.
Configuration: The IQ23x uses the standard IQ configuration
mode which enables configuration by way of the network, or
the supervisor port. SET can be used to create a strategy data
file (.IQ2) which can then be downloaded to the controller and
subsequently uploaded for backup purposes if connected to the
controller directly, by way of the network or by way of a modem.
A strategy data file from an IQ1xx controller (.IQF) can be
downloaded to an IQ23x and will require modification as
explained in the compatibility section
Modules: The strategy consists of a number of individual
functional blocks known as configuration modules. These
blocks can be linked in various combinations to enable plant to
be controlled in accordance with the building’s requirements.
The table lists the different types of configuration modules and
the number of each type available with IQ23x.

Full details of the modules are given in the IQ Configuration
Manual and Addendum. The IQ23x contains the normal IQ2
features as described in IQ Configuration Manual Addendum:
Engineers Journal (J), I/O Summary (i/o) Loader Issue (R(c),’c’
lower case), Serial Number (R(s), ‘s’ lower case), Supply
Frequency Option, Enhanced Logging, Module position, and
Strategy Cleardown. Differences between the modules covered
in the manuals and the IQ23x’s modules are covered below.
Address Module
It has two additional items described below:
default PIN disable: This increases the controller security by
disabling the default PIN. It is accessed using the character
“d”, setting d=1 will disable the default PIN. It may be enabled
by setting d=0 (as long as a valid PIN is used). This change
requires a PIN with level 99. If the default PIN is disabled and
the PIN settings are unknown (e.g PINs forgotten or after
battery replacement), the unit can be restored by clearing the
strategy using the address/baud rate switch zero reset and then
downloading the strategy.
Firmware
Communications: When operating as part of a Building
Management System, the IQ23x will be connected to other
devices by way of the Trend Network. This means that
information within the IQ23x can be accessed using one of
the Trend supervisor programs, or passed to other Trend IQ
controllers using inter‐controller communications, enabling the
sharing of information across the whole system.
When connected to the network the controller can use up to
2 different addresses. One address is for the controller itself,
the second is optional, and is for the supervisor port (locally
connected supervisor). The controller’s address is set by a
switch, and the supervisor port address is set up in the strategy
configuration (address module).
Hardware
Unit: The IQ23x is supplied in a metal enclosure. It has 4
mounting points which are on the same centres as the IQ111+
and IQ131+; they are also the same as those provided by the
IQ111 or IQ131 using the mounting bars. Its footprint is smaller
than IQ111 or IQ131, and the same as the IQ111 or IQ131 with
their mounting bars, but it is 13 mm deeper
Connectors: Two part connectors are used throughout
to facilitate wiring. An earth flange is provided for screen
termination with a special M3 earth stud close to the network
connection, and there are cleats for cable restraint.
Power: 230 Vac 50/60 Hz.
Note that this unit must be earthed (grounded) via the Earth
terminal of the IEC connector.
Fusing: The controller has no replaceable fuses; protection
is provided by means of a self-resetting thermally protected
transformer.
Indicators: LED indicators for receive and transmit network
current flow (RX, TX) and network OK ( ), also for all I/O
channels, power ( ), and fail ( ). See specification section for
details.
Network: The network terminals facilitate connection of 4 wire
cables. The standard Trend node features are included (TX,
RX, and network OK, , indicators, bypass relay, and network
alarm generation). There is also the facility for connection of a
supervisor or network display panel to the network by way of
the controller without the need for an additional node controller.
Internal Node: A node controller card may be fitted inside
the unit either as a pre-fitted option, or post-fitted using the
appropriate cables. There is a two pin polarised plug to supply
24 Vdc to the node and a four pin polarised plug which provides
a network connection. There is a set of two pairs of pins
adjacent to the network plug which are normally shorted by two
links; these must be removed when the node is connected. For
an integral node controller to operate the external network must
be connected, or the external network terminals must be linked
(TX to RX).
sUperv port addr: This operates as described in the IQ
Configuration manual addendum with the additional feature that
if the address is set to 120, the supervisor port will be disabled.
This gives increased security. The port can be enabled by
setting the address to another value by configuration or text
comms over the network.
Byte 506, Bit 1
This bit now has the fixed function of ‘IQ1 series simulation of
universal input action’ (see Compatibility section, Firmware).

IQ23x
Hardware (continued)
A node is post-fitted using KIT/NODE/IQ23x. This provides
mounting plates, pillars, screws, and cables to enable
connection of the current nodes (TMN, CNC2, PNC2, INC2,
LINC, and XN28); the node card is ordered separately. There
is a 25 way D type knockout on the upper panel for RS232
connection to the node, and a circular knockout for 14.25 mm
grommet for internetwork, PSTN, ISDN, or Lon cables.
The two links on each input channel must be correctly positioned
to set up the type of input required.

Address/Baud rate switch: The address on the Lan is set by
poles 1 to 7 in range 1, 4 to 9, 11 to 119 and must be unique on
the Lan. The baud rate is set by poles 8 to 10 in the range 1k2,
4k8, 9k6, 19k2 and must match the other nodes on the Lan.
The 4k8 baud rate is selected by setting all three poles to zero.
The address/baud rate switch may also be used to perform a
strategy cleardown; this is done by setting all the address/baud
rate poles to zero before power up (see Installation Instructions,
TG200539 sheet 3 and IQ Configuration Manual Addendum).
For this reason the address should normally be set non-zero.
Analogue Voltage Outputs 8
(IQ231: channels 1 to 8; IQ233: channels 1 to 12)
Link Headers
A range of link headers is available to enable the input channels
to accept a wider range of inputs:
LKE/5V: Provides 5V, 20 mA supply
13 ! N
Battery Backup: Details about the strategy configuration, time
and date, and logged data are stored in RAM. A plug‐in lithium
cell provides power to maintain the data in the event of power
failure, or the controller being switched off.
&
24 Vdc Auxiliary Supply: The IQ23x has a 24 Vdc auxiliary
500 mA supply protected by a self-resetting passive thermal
device. It is available from two terminals on the back of the unit
for relay modules, interfaces etc. and is completely separate
from other supplies.

Displays: The IQ23x can have two different types of local display; 2-line Display Panel or PC.
2-line Display Panel: The controller may be purchased with
a 2DP option fitted in the cover. Alternatively an external 2DP
(i.e. HDP, FPK, ENCLS/FP) may be connected by fitting the
KIT/2xx/RDS option which provides a 25 way D type female
connector on the upper face of the unit.
If a display panel is mounted in the front cover, it will not be
possible to connect an external 2-line display. The 2DP provides
access to parameters within the controller.
PC : A computer running a Trend Supervisor or Engineering
Tool can be connected to the Trend network by way of the
controller’s supervisor port without the need for an additional
node controller although it does take a separate network
address. When connected in this way the supervisor will have
access to all devices on the network, and will function as if it
were connected by way of its own node controller.
The diagrams below illustrate the various combinations in which the display panels and supervisor/engineering tools can be
connected.

Compatibility
Supervisors: 94x series, 921, 962, Viewpoint+.
Utility software: PowerTool, 822+/Toolbox version 6, SET, WupDn.
Controllers: It can communicate to other Trend IQ controllers using inter-controller communications.
Interface:
It can be connected to Trend interface modules. Check interface module specification to ensure compatibility.
Local Display: 2-line Display Panel (external or internal).
The IQ Configuration Reference Manual Addendum covers the compatibility between different types of strategy files, and between
the IQ23x sensor logs, and supervisors and software tools.
Compatibility with IQ111 (+), IQ131 (+)
Fixing
The IQ23x will fix to the same centres as the IQ111+ or IQ131+,
and as the IQ111 or IQ131 with mounting bars. If the IQ111 or
IQ131 weren’t originally mounted using the bars, then new fixing
holes will need to be drilled. The IQ111+ and IQ131+ also had
semicircular cutouts for mounting in the old small box (380 x
380 x 210 mm - no longer supplied); new holes would have to
be drilled to fix the IQ23x.
308 mm (12.13”)
263 mm (10.35”)
Size
The footprint of the IQ23x is smaller than the IQ111+, IQ131+,
and the IQ111, IQ131 with mounting bars. It is deeper than any

Power: The power connectors are all IEC plugs and in a similar
position.
Inputs/Outputs: These are all compatible 2 wide 2 part
connectors and it should be possible to unplug from the old
controller and into the IQ23x without rewiring unless the cables
were very tight (see I/O channels below). Note that early IQ111,
131 had single part terminals on the input channels.
External Display Panel: This has always used a 25 way D type
female connector, and it should be possible to unplug from the
old controller and into the IQ23x unless the cables were very
tight (see display panel below). Note that the IQ23x must have a
KIT/2xx/RDS fitted to support the external 2DP.
Network: The IQ111+ and IQ131+ have 8 wide network terminals
like the IQ23x and in the same position. However, the IQ111has
8 wide and the IQ131 has 4 wide terminals at the bottom of
the unit; this would require rewiring or using the appropriate
extension cables available in KIT/IQ23x/UPGRADE.
Auxiliary Output Supply: The IQ111, 111+, 131+ had a two
wire auxiliary 24 Vdc supply connector. This has moved to the
top edge of the IQ23x, so will require either rewiring or use of an
extension available in KIT/IQ23x/UPGRADE.
On the IQ131 there was a single +24Vdc terminal and the 0V
was taken from an adjacent channel linked so as to make the 0V
available from a terminal; on the IQ111 the polarity is reversed,
so with both these upgrades, even with the extension cable they
will require rewiring.
The IQ23x has a 500 mA auxiliary output supply which is
separate from the sensors, 2DP, and node supply. This is
greater than the IQ111, 131 (500 mA for auxiliary plus sensors,
2DP, node supply), and the IQ111+, 131+ (200 mA separate
supply).
Local Supervisor: The IQ111, 131 have a 25 way D type male
connector. The IQ111+, 131+ have a 5 way in line connector,
and the IQ23x uses an RJ11 connector. The cable should be
replaced with the standard supervisor adapter cable 9 way D
type female to RJ11, EJ101442. For NDP see below.

Channels 5 to 16: Universal, V, I, T, D
Channels 17 to 20 D only
IQ233 1 to 20 Universal channels, V, I, T, D 1 to 12 Analogue V channels
Generally the IQ23x can accommodate the I/O channel requirements of the controller it replaces. However, the IQ111, 131 had
outputs which could be linked for either current or voltage whereas the IQ23x has voltage only outputs.
If required, current outputs can be provided by adding 2VID, two channel voltage to current interface modules. If an SRMI
has been connected, it can be replaced by an SRMV or 2SRM (dual channel).
Although the IQ131+ can be replaced by the IQ233, the IQ131+ has a special arrangement of input channel types which affects the
fast sequencing of digital inputs (see Firmware section below).
Link Headers:
Link Header Used on Used for Replaced by on IQ23x
LK/A IQ111, 131 Regulated 5V supply at 20 mA LKE/5V
LK/B Regulated 15 V supply at 20 mA LKE/15V
LK/C Regulated 10 mA supply LKE/10mA
LK/D Adds thermistor input capability Link for thermistor T (not required on IQ131 as could be
linked for thermistor inputs)
LK/E Regulated 15 V through 4k7 ohms not supported
LK/F Desensitises digital inputs not required on IQ23x
LK/0 Externally powered current sensor Link for externally powered current sensor Ix
LK/5V IQ111+, 131+ Regulated 5V supply at 20 mA LKE/5V
LK/15V Regulated 15 V supply at 20 mA LKE/15V
LK/10mA Regulated 10 mA supply LKE/10mA
As can be seen from the above table, most of the applications requiring link headers are either achieved by the three new link
headers, or by appropriate input channel linking. The LK/E has no replacement but was rarely used.
Integral nodes
A node controller board may be fitted inside the IQ23x. The IQ23x may be ordered with a board pre-fitted, or it may be post-fitted
using the KIT/NODE/IQ23x. The node may be one of the current range of boards (CNC2, PNC2, INC2, TMNH, TMNE, LINC), or it
may be one of the older nodes (CNC, PNC, INC, MNC, ANC, AND, XNC, XN28, ENC).
Note that the IQ131 did not have a CNC built in to its firmware so that if the IQ131 was to be networked, it required a CNC to be
fitted which was connected directly to the IQ131 via RS232. Alternatively, a stand-alone IQ131 could have a modem connected via
an ANC or MNC, either of which was also connected directly to the IQ131 via RS232. If an IQ131 is replaced by an IQ23x its CNC is
redundant, and if an integral modem node (e.g. ANC, MNC) were fitted, it would now be connected to the controller via the network,
not by RS232 as previously. The IQ111, 111+, and 131+ all had a CNC built in to the firmware so this note does not apply to them.
A CNC was sometimes used for local supervisor or NDP network connection; these can now be connected via the local supervisor
port. The local supervisor port also supplies 24 Vdc to the NDP.

XNC220: This node replaces the XNC but is only available in a
boxed form (NBOX/XNC220) and cannot be mounted in an IQ.
ENC2: This node is used with the EMMPO2, but is only available
in boxed form (NBOX/ENC2) and cannot be mounted in an IQ.
Baud Rates: All the nodes are capable of being linked for 1k2,
4k8, 9k6, or 19k2 baud for both of the network connections (Lan
A, Lan B); except for the LINC which can only be linked for 1k2,
9k6 or 19k2. The IQ23x is capable of all 4 baud rates. The INC2
is also capable of being linked for 38k4 baud on its internetwork
or internetwork segment B port (Lan B).
Display Panel
The IQ23x can have an integral 2 line display panel either
pre‐fitted, or post-fitted (by replacing the cover with COVER/
DP2/IQ23x). The display panel looks different to that of the
IQ111 or 131, as the membrane has been through a layout
change. However, although the arrow and letter keys are in
different places, they have the same functionality.
Note that an integral display panel fitted in an IQ111(+) or
IQ131(+) may not be used with an IQ23x.
An external 2 line display panel (e.g. HDP, FPK) could be
directly fitted to an IQ111 (+),131 (+). The same display panel
can be connected to an IQ23x, but it requires the internal fitting
of KIT/2xx/RDS, the remote display panel support kit.
Controller Baud Rates
The controllers have different local supervisor port, and
network baud rates. The network baud rate is set by a link; the
supervisor baud rate is now fixed at 9k6 but was configurable by
link on the earlier controllers. The IQ131 is unique in not having
CNC functionality built in to its firmware so it needed a CNC to
be fitted, and the network baud rate is set by a link on the CNC
board.
Controller Address
The IQ111 controller address was set in configuration mode so
it should be checked in configuration mode before replacement.
The IQ131 address is set by DIL switches on its CNC. The
Address is set by DIL switches on the controller board for
IQ111+, 131+, and IQ23x.
Firmware
File compatibility: The IQ23x module suite has either the same
or greater numbers of modules than the IQ111 (+), 131 (+). The
IQ111 (+), 131 (+) strategy can be uploaded into a strategy file
(.IQF) using Power Tool or WupDn. It can then be downloaded
into the IQ23x.
Special cables are required to connect to a PC for uploading from
IQ111 (+), IQ131 (+). The IQ111, 131 requires CABLE/58-0750
(9 Way Female D type to 25 Way Male D type), and the IQ111+,
131+ require the additional adaptor CABLE/78-1172 (25 Way
Female D type to 5 in line Stocko).
Certain modifications are required for it to run correctly, and this
can either be done in the controller using configuration mode
(via PowerTool or WupDn), or the strategy file can be uploaded
(as an .IQ2 file) into SET and the changes made there before
downloading to the IQ23x.
If strategy diagrams are required they can be loaded into SET
from an earlier ACE or SET file, or can be laid out in SET
from the strategy file (uploaded from the IQ23x after an .IQF
download as either an .IQ2 or .SCN file).
The standard IQ1xx to IQ2xx modifications are described in the
IQ configuration Manual Addendum (TD200118).
Bit 506,1: This bit is used to set Emulation for IQ1xx Universal
Inputs. It applies in the case where an internal sensor module is
used in internal digital mode.

In IQ1xx controllers, if a sensor (whose number is greater than
the number of real input channels) is set to internal digital mode,
it will take the value from an internal digital node and write it to
its analogue node and digital input node.
10 IQ23x Series Controllers Data Sheet TA200538 Issue 2, 18-Jan-2012

Data Sheet
IQ23x
Firmware (continued)
In IQ2xx controllers the sensor only writes to the analogue
node (not to the digital input node) Bit 506,1 should be set to 1.
If an IQ1xx strategy using the internal digital sensor output to
an internal digital input node connection is downloaded to an
IQ2xx setting the bit to zero restores IQ2xx mode.
Sharing Labels: As explained in the IQ Configuration Manual
(90-1533), the IQ111 (+), 131 (+) sensor and digital input
modules share labels. The IQ23x has separate labels so that
in a file transferred from IQ1xx to IQ2xx, the sensors will have
the original labels, and the digital inputs will need their labels
to be set up.
IQ131 (+) Input Channels: The differences in the arrangement
of input channels on the IQ131 (+) and IQ231 produce some
upgrade problems. The IQ111 (+) upgrade doesn’t have similar
problems as the controllers have the same numbers of input
channels.
Fast Sequencing of Digital Inputs: The fast sequencing on
the IQ131+ was set up so that fast sequence input references I1
to I4 referred to input channels 17 to 20, and references I5 to I8
referred to input channels 5 to 8. (Note that all other references
remained the same e.g. configuring module I1 set up internal
digital input 1 for node 1,0 which corresponded to input channel
1).
In the IQ23x, the fast digital input channel references I1 to I8
refer to input channels 1 to 8. When an IQ131+ file is transferred
to the IQ23x, fast sequence I1 now refers to input channel 1.
If fast sequencing was required on fast sequence inputs 1 to
4 it would require channel connections to be changed and the
associated strategy to be transferred across the channels.
IQ131 Internal Digitals: The IQ131 internal channels start at
17 whereas in the IQ23x, channels 17 to 20 are real. So if the
IQ131 strategy used an internal digital in the range 17 to 20,
it would get overridden by the real input in the IQ23x. If such
internal digitals were used, they should be moved to a area of
unused internals on the IQ23x (digital input 21 onwards).
