SS 4.1 MLR/RJ Installation and Operation Manual
OPERATION
SERIAL OPERATION
RS-232 Serial Control
Connect one end of the modular cable to the RJ11 jack on the rear panel of the prod-
uct and the other end to the RJ11 to the jack on the “S9” 9-pin female D-sub adapter.
Connect the 9-pin female D-sub “S9” adapter to the COM port of the controlling PC.
The default protocol is as follows: 9600, N, 8, 1 (other baud rates are user selec-
table). Select the desired unit ID address for each unit using the configuration DIP-
switches, zero is the factory default setting. Never duplicate addresses.
Note: If your PC does not have a built-in RS-232 serial port but does have USB,
then a USB-to-serial adapter cable is a good way to add serial capability. We
recommend USB-to-serial adapter cables that use the FTDI chipset and have
had good results with the model “SBT-FTDI” from Sabrent.
