Code Operated Matrix Switch

30

Important Configuration Notes:

• Your COMS port, LINKUP, and DOS must be

configured exactly the same way (see the
instructions above for more details).

• The fastest data speed possible with DOS MODE

COM commands is 9600 bps.

• If you’re sending graphics data, you’ll probably

need to configure everything for an “8-bit” (data
bits) word length.

• DOS and many application programs use

hardware flow control (CTS input Pin 5). See
the COMS manual for how to configure the
COMS unit for hardware flow control.

• The attention string configured in LINKUP

must match the attention string for your COMS
port.

• The COMS unit’s BREAK DETECTION option

for your port must be set to “BREAK TO DIS-
CONNECT” in order for the LINKUP support
program to execute all of its menu options.

PROBLEM: I’m still having problems.

If you still need help, check these sources:

• Your COMS user’s manual for information on

hardware problems.

• LINKUP’s on-line help information.

• Your DOS manual for help on any of the DOS

commands, and also on EDLIN (the editing pro-
gram you can use to create or change your
AUTOEXEC.BAT file).

NOTE: You have to configure the COMS, LINKUP,

and DOS only once, not every time you run
LINKUP.

The COM port on your computer is connected to
the COMS with a serial communications cable. In
order for the LINKUP and DOS to successfully
communicate with the COMS, make sure you follow
these recommendations:

• Set the COMS DTE/DCE shunt jumper in the

DCE position.

• Connect the  PC COM port to the COMS port

with a straight-through cable (not a null-modem
cable).

• Make sure your cable supports these signals:

TXD, RXD, CTS, DSR, GND, DCD, and DTR.
