Using the Parallel Port 7-3

Selecting BCD or Binary Data

Format

The parallel port will accept data and message triggers in either a binary or

Binary Coded Decimal (BCD) format or in non-coded discrete form which

allows the DL5 to easily replace pilot lights as described in Chapter 10.

Each numbering system, binary or BCD, has its own merits. Your choice

will often be based upon the format used by your controller. Both the

binary and BCD numbering systems allow you to address all 999 possible

message numbers but vastly different maximum variable values. The

maximum variable value that can be input in binary or BCD run modes is

shown below:

You must select which format best suits your needs and then select the run

mode as described in Chapter 8.

Run Mode Maximum Message # Maximum Variable Value

BCD 999 3,999

Binary 999 16,383

1 2 ... 48 49 50 51 52 53 54 55 56 57 58 ... 118 119
