1.
Unplug the device and make sure there is no power to the instrument.
2.
Unscrew the six screws on the top of the instrument and remove the top hatch cover to reveal the DI-8B back-
plane.
3.
Plug the DI-8B module firmly into one of the channel positions clearly labelled on the backplane and secure with
the set screw. Note: Be sure to completely screw the module into place or vibrations could short the system. DI-
8B modules are installed on (or removed from) the socketed DI-8B backplane (located on the circuit board) and
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.
