Interfacing to switches and other devices
The STB-26 terminal board provides a convenient way of interfacing switches or
other digital I/O devices to the I/O ports. I/O lines at the connector can be
connected to an STB-26 with a CMA-26 cable. Parallel I/O devices are then
connected to the screw terminals on the STB-26. The illustration on page 60 shows
an STB-26 terminal board connected to the digital I/O. Refer to the STB-26 product
sheet for more information.
Opto-module rack interface
You can interface digital I/O lines to an 8-, 16-, or 24-position opto-module rack.
One end of the CMA-26 cable plugs into the I/O connector and the other plugs into
an MPB–8, MPB–16, or an MPB–24 opto rack. Refer to the
MPB opto racks
data
sheet
for more information.
You can also use a CMA–26 cable to connect the I/O port to an STB–26 terminal
board and then to the opto rack. The STB–26 has two 26-pin connectors, one of
which connects to the I/O port, the other which connects to the opto rack. The
illustration on page 60 shows both of these configurations.
For either configuration, run a separate power line to +5V and ground on the opto-
rack.
Use the following table to determine the corresponding opto-channel position for
ports A, B, and C.
