Using a PC as a CIT
6
In addition to CIT functions, a PC is required for software downloads and
facilitates software program updates. Any
MS-DOS
*
PC can be used to emulate a
traditional CIT through a variety of low-cost terminal emulator software packages;
thus, an
MS-DOS
PC can serve DDM-2000 FiberReach Multiplexer needs very
efficiently. In addition, the DDM-2000 FiberReach Multiplexer user interface can
be accessed from within
MS-Windows
* (Version 3.0 or later) on an
MS-DOS
PC.
The DDM-2000 FiberReach Multiplexer uses flash erasable program memory
(EPROM) devices that can be upgraded through direct download from an
MS-
DOS
PC. Upgrades are made available through the distribution of floppy disks
compatible with the recommended PCs.
NOTE:
The DDM-2000 FiberReach Multiplexer CIT interface supports data rates
up to 19,200 baud but does not provide flow control. Some terminals and
PCs when set for higher data rates will not work properly at these rates with
equipment like the DDM-2000 FiberReach Multiplexer that does not provide
flow control. The system may appear to stop working when reports or long
prompts are displayed. If this happens, try setting the terminal to a lower
data rate. The data rate of the DDM-2000 FiberReach Multiplexer is
automatically set to match the data rate of the terminal (autobaud).
Remote Access Using the DCC
6
The DDM-2000 FiberReach supports CIT remote access from the local terminal
to a remote DDM-2000 using the DCC. The DDM-2000 FiberReach supports one
incoming remote login session and one outgoing login session over the DCC at a
time. For example, a local user can gain remote access to a remote system in
their same subnetwork at the same time as a remote user at another DDM-2000
in the subnetwork can gain remote access to the local system.
