Hardware Options
Several hardware options are available for customizing the Scanner 2000 to a user’s specific needs.
Input/Output Expansion Board (Kit: PN 9A-30188004)
An expansion board allows the instrument to support a differential pressure meter run and two turbine meter
runs simultaneously. The board features a turbine input, a pulse input, two analog inputs, an analog output,
and 256 KB of memory. See Appendix A—Scanner 2000 Hardware Options for wiring diagrams.

Explosion-Proof Control Switch (CSA: PN 9A-30054001; ATEX: Part No. 9A-30054002)
During normal operation, the LCD displays the selected parameters in a continuous scroll. The explosionproof
control switch allows the user to manually control the display of parameters on the LCD and view
daily logs instantaneously without removing the instrument cover. The control switch is available in both a
CSA-approved model (Part No. 9A-30054001) and an ATEX-approved model (Part No. 9A-30054002). See
Appendix A—Scanner 2000 Hardware Options for details.
Explosion-Proof Flexible RTD
The Barton Model 21 flexible armored RTD temperature sensor provides live temperature to the Scanner
2000. It is installed in a threaded conduit opening in the Scanner 2000 housing, and requires no conduit seals
for installation. This instrument is CSA-approved for use in hazardous area installations. See Appendix A—
Scanner 2000 Hardware Options for details.
Explosion-Proof Communications Adapter (CSA: PN 9A-90017004; ATEX: PN 9A-90017008)
The explosion-proof communications adapter provides a quick-connect option for communicating with the
Scanner 2000 (downloading logs, for example) via laptop or PC without removing the instrument cover.
Optional accessories include an RS-232 to RS-485 converter. The COM adapter is available in both a CSAapproved
model (Part No. 9A-90017004) and an ATEX-approved model (Part No. 9A-90017008). See
Appendix A—Scanner 2000 Hardware Options for details.
External USB Communications Adapter (CSA: 2295524-01; CSA KIT with CD: 2295634-01)
The USB communications adapter allows the connection of a Scanner 2000 directly to a USB port of a laptop
or PC. A user-supplied universal USB cable is required. The adapter is factory-installed when purchased with
a Scanner 2000. It is also available as a kit with an installation CD for upgrading communications in a field
unit. See Appendix A—Scanner 2000 Hardware Options for details.
Pole-Mounting Kit (PN 9A-30028004)
A hardware kit consists of a mounting bracket, two U-bolts and nuts allows the Scanner 2000 to be mounted
on a 2-in. pole. The mounting bracket also provides the extension necessary to keep the instrument in a
vertical position when it is bulkhead-mounted to a flat, vertical surface. See Pole-Mount Installation, page 27,
for details.
