COURIER HIGH SPEED MODEMS
6. The final step is to connect the modem to the computer's or
terminal's serial port with the RS-232 cable described earlier
in this chapter. Attach the appropriate connectors to the
modem and to the serial port.
NOTE: To prevent overheating, do not cover the vents on the
top of the modem case.
The modem is now ready to be tested and operated.
TESTING THE INSTALLATION
Use the following procedures to verify that your modem is
working properly.
1. Turn on your computer or terminal and clear the screen.
Then turn the Courier's power switch ON. The following
front panel indicators, or LEDs, will light up.
CD Carrier Detect, if you have set DIP switch 6 ON,
enabling the CD override
MR Modem Ready /Power ON
CS Clear to Send
TR Data Terminal Ready, if you have set DIP switch 1 ON,
enabling the DTR override
For more information on the front panel indicators, see
Appendix B.
2. Set your terminal or software to 19.2K bps or 9600 bps. In
addition, set a word length of either 7 bits plus 1 parity bit,
or 8 bits with no parity-it doesn't matter which now-and 1
Stop bit.
3. If you're using a personal computer, load your communica-
tions software. If your software allows, perform the function
that lets you send AT commands to the modem, that is, puts
the computer in Terminal Mode. Some communications
programs do this automatically upon loading. Others
require you to display a communications or terminal screen,
type a Function key, or perform some other operation.
If necessary, refer to your communications software docu-
mentation for instructions.
