Setting Up the apC/8X Main Panel
S1:4
S1: 4 enables apC/8X dialup communication mode. Set S1:4 to ON to operate
in dialup mode. (Note: for dialup operation, switch S1:3 must also be set to
OFF.) Set S1:4 to OFF to disable dialup communication.
Note:
If you change any S1:n switch settings, we recommend that you
set S1:1 to ON and press the reset button (S7). Then set S1:1 to
OFF.
S1:5–S1:7
Switches S1:5 through S1:7 set the baud rate at which the apC/8X
communicates with the host computer. Set the baud rate to the highest rate
compatible with the host. (The maximum baud rate supported for RS-485 is
9600.) If the devices are physically far apart or if communications errors
occur, lower the baud rate.
All apC/8Xs in a chain must run at the same rate. If you are using a modem,
set these switches to match the baud rate of the modem. Baud rates and their
corresponding switch settings are as follows:
