Thumbwheel Port Digital Inputs and Outputs

The inputs and outputs on the thumbwheel multiplexer port of either the Acc-1P or the Acc-2P boards may be used as discrete, non-multiplexed I/O. In this case, these I/O lines can be accessed through M- variables that are defined according to the setup of the address selection jumpers. Jumper E6 on the Acc-

1P or E5 on the Acc-2P determine which set of the following M-variables are used:
