Use of Terminal
Description
This paragraph describes which terminals are approved for use with the DDM-2000
OC-12, how to set up the terminal, and some DDM-2000 OC-12 command notes. The
use of a terminal is optional.
Compatible Terminals
The DDM-2000 OC-12 craft interface terminal (CIT) port will support rates of 300, 1200,
2400, 4800, 9600, and 19,200 baud, and should be compatible with most ASCII
terminals.
The DDM-2000 OC-12 will output information to fit in a display area of 24 lines (default)
by 72 characters. The number of display lines can be altered with the
set-link
command.
ASCII Terminal Setup
The DDM-2000 OC-12 provides a serial ASCII terminal interface through a 25 pin
female connector mounted on the user panel. The connector provides an EIA-232D
interface for use with most common terminals, provided that the following interface
parameters are set properly:
* The ASCII terminal can be set for baud rates of 300, 1200, 2400, 4800, 9600, or 19,200. However,
the baud rate of the DDM-2000 OC-12 (which is controlled by the switches on the SYSCTL) and the
ASCII terminal must agree.
DDM-2000 OC-12 supports data rates up to 19,200 baud, but it does not provide flow
control. Some terminals and PCs that can be set for higher data rates will not work
properly at these rates with equipment like DDM-2000 OC-3 that does not provide flow
control. The system may appear to stop working when reports or long prompts are
displayed. If this happens, set the DDM-2000 OC-3 and the terminal for a lower baud
rate.
