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 17 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
Plug the SCC-CTR01 general purpose counter timer module into socket
J19 or J20 of the SC-2345. Socket J19 connects to the DAQ device
general-purpose counter timer channel 0. Socket J20 connects to general
purpose counter timer channel 1.
