SRC-32 Installation and Operation Manual
INSTALLATION
Pair Mode
The SRC-32 can be used to transmit the outputs from one unit to another over a seri-
al connection. The logical sense of the inputs is inverted when written to the outputs
of its corresponding unit. Normally inputs are high and when closed go to a logic 0
when in pair mode. When logic 0 is received, it will write logic 1 to the output.
This allows the relays connected to outputs 1-8 to come on if its corresponding input
is closed. Multiple units can also be set up to communicate with the same number
of units on the other end of a data link. All units must have DIPswitches 5 and 6
turned on and the unit addresses must have a corresponding unit on the other end of
the link set to the same address. For example, if you have two units on each side set
to address 0 and 2, then the two units on the other side of the data link must also be
set to 0 and 2. All units will automatically transmit the states of their inputs on
power up, every ten seconds and when any input changes states. If a unit does not
receive an update from its corresponding paired unit for a period of 20 seconds, its
LCD display will begin to flash “COM - FAILURE”. As soon as communications
is restored, the “COM – FAILURE” message will clear.
