are secured with a non-removable mounting screw. Each channel position is labeled “CHANNEL 1,” “CHAN-
NEL 2,” etc. on the socketed backplane. The DI-8B modules can be mixed or matched in any combination suit-
able for the application and are identical in pinout and size, so it doesn't matter which module gets plugged into
which channel position

top hatch to indicate which module is installed at each channel position.
