SRC-4 Installation and Operation Manual
INSTALLATION
Outputs 1-4 represent the string data that will be sent over the serial port when
inputs 1-4 are activated. Each output channel can have a custom ON and OFF string.
Special characters may be entered as ASCII HEX characters, to do so enter a “/” fol-
lowed by the hex value. For example, if you want to send 12345(CR/LF) enter as
the string: 12345/0D/0A and hit the ENTER key to terminate. Each string may be up
to 14 characters long.
To enter strings for an output channel first type the channel number (1-4) followed
by the desired ON string, press enter to complete the string, then type the desired
OFF string, press enter to complete the string. The settings will be saved and you
may enter strings for another channel.
Inputs 1-4 represent the strings that control relays 1-4. Each input channel can be con-
figured for custom ON and OFF (latching) strings or for a custom ON (pulse) string.
To enter strings for an input channel first type the channel number (5-8) followed by
0 for Pulse mode or 1 for Latch mode, then enter the desired string(s) and press enter
to complete each string. The settings will then be saved and you may enter strings
for another channel. Each string may be up to 14 characters long.
Once you have finished programming the SRC-4 you can power the unit down,
switch it to the Data operation mode and begin using it.
