of extended I/O on the controller. Each bank is individually configured as an input or output bank by inserting the appropriate integrated circuits and resistor packs. The hardware configuration of the IOM-1964 must match the software configuration of the controller card.

All DMC-2x00 series controllers have general purpose I/O connections. On a DMC-2x10, -2x20, - 2x30, and -2x40 the standard uncommitted I/O consists of: eight optically isolated digital inputs, eight TTL digital outputs, and eight analog inputs.

The DMC-2x00, however, has an additional 64 digital input/output points than the 16 described above for a total of 80 input/output points. An 80 pin shielded cable connects from the 80 pin connector of the DMC-2x00 to the 80 pin high density connector on the IOM-1964 (J5). Illustrations for this connection can be found on pages 10 and 11.

Configuring Hardware Banks

The extended I/O on the DMC-2x00 is configured using the CO command. The banks of buffers on the IOM-1964 are configured to match by inserting the appropriate IC’s and resistor packs. The layout of each of the I/O banks is identical.

For example, here is the layout of bank 0:

All of the banks have the same configuration pattern as diagrammed above. For example, all banks have Ux1 and Ux2 output optical isolator IC sockets, labeled in bank 0 as U01 and U02, in bank 1 as U11 and U12, and so on. Each bank is configured as inputs or outputs by inserting optical isolator IC’s and resistor packs in the appropriate sockets. A group of eight LED’s indicates the status of each
