Bay Technical Associates V79 PDI-1 - Manual (Page 23)

19
If you issue the RL1<cr> command (Report Event Latch Data for Channel 1), the
module will respond with a message showing the state of the input that started the
initial event. This will be "1" (closed) for LO to HI Latch Polarity or "0" (open) for
HI to LO Latch Polarity if using the PDI-1. This will be "1" (voltage detected) for
LO to HI Latch Polartiy or "0" (no voltage detected) for HI to LO Latch Polarity if
using the PDI-2. If time tagging is enabled, the time the initial event occurred will
be appended to the event sample.
5 CONFIGURATION
You may program the PDI-1 or PDI-2 using a menu-driven configuration
procedure from a host module or the M Series service port as described in Section
5.1 or by sending dynamic configuration commands from a host module as
described in Section 5.2. You may view the current configuration from the front
panel (see Section 5.3).
5.1 MENU-DRIVEN CONFIGURATION
To access the menu-driven configuration mode of the PDI-1 or PDI-2 from any
host module, use the following procedure:
1. Configure the host terminal's serial parameters to match those of
the host module. From the factory, the host module is set at
9600 baud, 8 bit word size, 1 stop bit, no parity, and XON/XOFF
disabled. If you do not have a dumb terminal or a terminal
emulation program, BayTech supplies a utility diskette which
includes software to put an IBM PC or compatible into a terminal
mode (TERM.EXE).
2. Connect to the PDI by sending the port select code, the
appropriate Unit Number followed by a colon (1: to 30: - only if
using cascaded units), the desired module number (2 to 16), and
Carriage Return or Line Feed.
3. Access configuration mode by sending $CONFIG<cr> .
