Configuring Hardware Banks

The extended I/O on the DMC-1415/1416/1425 and DB-14064 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:
Resistor Pack for
Resistor Pack for
inputs
Resistor Pack for
outputs
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
I/O point. The numbers above the Bank 0 label indicate the number of the I/O point corresponding to
the LED above it.

Digital Inputs

Configuring a bank for inputs requires that the Ux3 and Ux4 sockets be populated with NEC2505
optical isolation integrated circuits. The IOM-1964 is shipped with a default configuration of banks 2-
7 configured as inputs. The output IC sockets Ux1 and Ux2 must be empty. The input IC's are labeled
Ux3 and Ux4. For example, in bank 0 the IC's are U03 and U04, bank 1 input IC's are labeled U13
