SOURCE/SINK DIGITAL I/O CONFIGURATION
The digital inputs and outputs are configured by moving two IC’s on the
control circuit board located directly behind the front panel. Be sure that the
power is OFF and then remove the top cover. The components may be
moved using a small screwdriver to pry the IC’s from the socket strips.
Select the “Source” or “Sink” location and reinstall the components. They
are not required to be set the same – one may be “Source” and the other
“Sink” to best match the required interface signals.
The optical isolator for the Digital Outputs (DO) is shown in the default
“Source” configuration.
The outputs may be switched to “Sink” by moving this IC to the alternate
location as shown below.
The digital inputs
may be
reconfigured in the
same manner.
They are also set
for “Source” as the
factory default as
shown above.
Digital Inputs
shown configured
for “Sink.”
