DB-15072 OPTO-22 Expansion Option
The DB-15072 is a version of the DMC-1500 that provides an interface to up to 72 OPTO 22 I/O
modules. The first 24 I/O points can be configured through software. I/O points 25 through 48 can be
configured as inputs or outputs (in groups of 8) and the I/O configuration options are shown below.
I/O points 49 through 96 are always inputs. Each group of 24 I/O points is brought out via a separate
50 pin cable which plugs directly into an H-style OPTO 22 rack.
Configuring the I/O for the DB-15072
The I/O on the DMC-1500 is organized in 8 bit increments known as blocks. The extended I/O is
configured as blocks 3-9. Blocks 3-6 can be configured as inputs or outputs, using the command, CO.
The command has one field:
CO n
where n is a 3-bit number represented in decimal. A 3 bit number ranges, in decimal, between 0 and 7.
Each bit in the 3-bit number represents one of the 8-bit I/O blocks. If the representative bit is one, the
corresponding I/O block will be configured as an output.

The simplest method for determining the proper value for n is to do the following: 1. Choose which
8-bit I/O blocks that should be configured as outputs. 2. From the table, determine the decimal value
for each I/O block to be set as an output. 3. Add up all of the values determined in step 2. This is the
value to be used for n.
For example, if blocks 4 and 5 are to be outputs, then n is 3 and the command, CO3, should be issued.
This parameter, and the state of the outputs, can be stored in the EEPROM with the BN command. If
no value has been set, the default of CO 0 is used (all blocks are inputs).
When configured as an output, each I/O point may be defined with the SBn and CBn commands
(where n=9 through 56). OBn can also be used with n=9 through 56.
