5.2 DYNAMIC CONFIGURATION PROCEDURE AND
COMMANDS
PDI-1 or PDI-2 dynamic configuration commands are issued through a host
module. Some configuration commands apply to all types of DAC modules, while
others apply to specific modules. The PDI will recognize dynamic configuration
commands only when Dynamic Configuration is enabled (see Section 5.1.5). Use
the following procedure to send dynamic configuration commands to the PDI
from a host module:
1. Select the PDI from the host module 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: - only if using cascaded units), the
desired module number (2 to 16), and a terminating character of Carriage
Return (0D Hex) or Line Feed (0A Hex). For example, to select an PDI
Module located in slot 15 of a non-cascaded unit using the default port
select code, send
$BT15<cr> .
2. Once the PDI is selected, it will go into Command Mode and allow you to
send dynamic configuration commands. The PDI configuration
commands begin with two capital letters designating the specific
command and are terminated with a Carriage Return. Most configuration
commands require a number between the command letters and Carriage
Return. This number represents the desired configuration parameter.
3. After you have sent the desired configuration command(s) to the PDI
module, you may disconnect from the PDI, by sending
$BT<cr> . You
may disconnect from the PDI and select a different module or the base
unit by sending
$BTX<cr> , where X is the desired module number or 0
for the base unit.
Section 5.2.1 and Section 5.2.3 provides detailed information on the functionality
of each configuration command supported by the PDI. Appendix A provides these
commands as a quick reference.
