BASE UNIT AND MODULE CONFIGURATION

____________________________________________________________________________

1. Select the V79 PDI-1 from a config port by sending a select

sequence which consists of the port select code ($BT - default), the

appropriate unit number followed by a colon (01: to 30: - for

cascaded units only), the desired module number (2 to 16), and a

terminating character for <cr> (0D Hex). For example, to select a

V79 PDI-1 Module installed as Module 15 of a non-cascaded unit

using the default port select code, send $BT15<cr>.

2. Once the V79 PDI-1 is selected, it enters Command Mode and

allows you to send dynamic configuration commands. The V79

PDI-1 configuration commands begin with two capital letters

designating the specific command and are terminated with <cr>.

Most configuration commands require a number between the

command letters and <cr>. This number represents the desired

configuration parameter.

3. After you have sent the desired configuration command(s) to the

V79 PDI-1 module, you may disconnect by sending $BT<cr>. You

may disconnect from the V79 PDI-1 and select a different module

or the base unit by sending $BTn<cr>.

NOTE: Multiple configuration commands may be sent while the V79 PDI-

1 is in command mode. Each command should be terminated with <cr>.

For example:

RM1<cr>TT2<cr>

DEBOUNCE DELAY COMMAND

The Debounce Delay (DB) command programs the PDI Debounce Delay time. The

Debounce Delay command has the following format:

DBn<cr>

where n = 0 to 65535 milliseconds.

REPORTING METHOD COMMAND

The Reporting Method (RM) command programs the PDI Reporting Method. The

Reporting Method command has the following format:

RMn<cr>

where n = 1 to 3. 1 = Command, 2 = Immediate and 3 = Schedule.
