PIOU/PIOUS/RSSU/RSIU Setup➤To check the DKAdmin/DKBackup communications setup
1. From the Options/System Installation/Communication Setup menu, verify that the proper
COM port is selected and that the communications parameters are set as follows:
2. PIOU or PIOUS PCB installed on Strata DK which is connected to DKAdmin/DKBackup
PC: if using an IMDU, verify that the switch SW2 is set for 1200 bps (LED CD4 off) and
that SW3 is set to “MODEM.”
If connecting an external modem, PDIU-DS, or PC COM port directly to the TTY
modular jack, verify SW2 is set to the “TTY” position.
3. RSSU does not support the IMDU built-in modem or SMDR, and it has no option
switches. Its communication parameters (TTY port) are always 1200 bps, even parity, 7
data bits, 1-stop bit.
4. Use Program 03 to identify the PCB slot that contains the PCB with the TTY port or
modem that will be used (Code 41 for PIOU, PIOUS, or RSSU or Code 49 for RSIU).
5. Use Program 76 if RSIU/RSIS/RMDS is used to connect with the DKAdmin/DKBackup
PC.
6. Use Program 77-1 (LED 14 and 15) if IMDU or RMDS is used to connect to the
DKAdmin/DKBackup PC.
Communications port: COMX (X = 1, 2, 3 or 4)
Baud rate: 1200 (If using RSIU TTY port or RMDS,
the Baud rate can be higher than 1200 bps.)
Parity: Even
Data bits: 7
Stop bits: 1
