SCC Quick Start Guide
Digital SCC Modules
Sockets J9 to J16 work for digital SCC modules as well as for analog
inputs. Plug a digital SCC module into any socket J(
X
+
9), where
X
is 0 to 7,
and connect the P0. signal to the module. The SC-2345 routes the P0. signal
to the DAQ device channel P0.(
X
). Figure 18 illustrates a digital module
with an analog input module.

Analog Output SCC Modules
You can plug analog output SCC modules into the SC-2345 using sockets
J17 and J18. Each socket connects to both analog output channels of the
DAQ device although each is identified on the SC-2345 as being for either
channel 0 or channel 1. These designations indicate the primary analog
output channel each socket uses. Analog output channel 0 is the primary
channel for socket J17. Analog output channel 1 is the primary channel for
socket J18.
GPCTR SCC Modules
You can build GPCTR circuitry onto the SCC-FT01 feedthrough module.
Plug the custom GPCTR SCC module into socket J19 or J20 of the
SC-2345. Socket J19 connects to the DAQ device GPCTR channel 0.
Socket J20 connects to GPCTR channel 1.
