DMC-3425 Appendices• 181
For example, if block 8 is configured as an output, the following command may be issued:
OP 7,,,,7
This command will set bits 1,2,3 (block 0) and bits 65,66,67 (block 8) to 1. Bits 4 through 8 and bits
68 through 80 will be set to 0. All other bits are unaffected.
When accessing I/O blocks configured as inputs, use the TIn command. The argument 'n' refers to the
block to be read (n=0,2,3,4,5,6,7,8 or 9). The value returned will be a decimal representation of the
corresponding bits.
Individual bits can be queried using the @IN[n] function (where n=1 through 8 or 17 through 80). If
the following command is issued;
MG @IN[17]
the controller will return the state of the least significant bit of block 2 (assuming block 2 is configured
as an input).
Connector Description:
The DMC-3425 controller with DB-14064 has two 50 Pin IDC header connectors. The connectors are
compatible with I/O mounting racks such as Grayhill 70GRCM32-HL and OPTO-22 G4PB24.
Note for interfacing to OPTO-22 G4PB24: When using the OPTO-22 G4PB24 I/O mounting rack,
the user will only have access to 48 of the 64 I/O points available on the controller. Block 5 and Block
9 must be configured as inputs and will be grounded by the I/O rack.
