Communication Port
The Communication Port selection is available only for “SS2000” and “Modem” modes.
This setup option determines which serial port on the SFCDWARE computer will be used to
interface with the SS2000D or modem that is used to communicate with the RTUs. The possible
options are COM1, COM2, COM3, and COM4.
To change the current selection, point & click on the radio button; each time the radio button is
pushed, the display will scroll through the possible options, one at a time.
Front Porch Time
The Front Porch Time selection is available only for “Modem” mode.
Front Porch is the dead time between transceiver PTT (Push To Talk) and the start of data
transmission (0 – 9999 ms).
Number of Communication Retries
This setup option determines how many times the CCU will try to contact an RTU before
considering the communication attempt to be a Comm Fail. The CCU will wait between tries the
number of seconds indicated by Retry Delay. Retires may be set to a minimum of 1 and a
maximum of 3.
To change the number of retries, point & click on the radio button. Each time the radio button is
pushed, the display will rotate to the next higher number, up to a max. of 3, at which point the
numbers will restart at 1.
Retry Delay
This setup option determines how many seconds to wait between attempts to contact an RTU.
For Program commands 10 seconds will automatically be added to the retry delay. This will
prevent the lengthy program command from causing a Com Fail.
The format of this data entry field is from 1 to 99 seconds. To change the Retry Delay, highlight
the current retry delay number and enter a new number. The setting of this parameter is
dependent on the radio system infrastructure, however 10 is an optimum setting for most
systems.
CCU Address
This setup option assigns the CCU site address. The valid address range is 900-909. Primary
CCU sites are 900-904 and secondary CCU sites are 905-909.
