Comtrol RM i PCI V.90 - Manual (Page 3)

8. Press D to test the serial I/O and IRQ. (The T and M
options are discussed under Terminal Mode, below.)
The diagnostic tests each RocketModem card’s serial
I/O, IRQ, and telephone type, and displays the
results.
9. Press any key to continue. If you have more than one
card installed, the diagnostic repeats until all cards
have been tested.
10. Press any key to continue. The diagnostic displays a
summary of the test results.
11. Press any key to continue.
The diagnostic resets all modems and reinitializes
all RocketModem boards.
12. Press Y to restart the diagnostic at Step 3 (for
example, to enter Terminal Mode), or N to quit.
If you select N, remove the diagnostic diskette from
the drive, then press the spacebar or Enter key to
boot the system. Do not use the CTRL-ALT-DEL
reboot command. Use of this command may result
in CMOS errors on some systems.
Note: The Terminal Mode option is used to test modems
by dialing out using AT commands. For an
example of how to use this option, see Terminal
Mode, later in this Installation Card.
Troubleshooting
If an ISA-bus modem card fails to initialize, check to
make sure you have selected the correct I/O address and
IRQ. If that does not solve the problem, try removing the
card and reseating it in another slot.
If you have tried any “short cuts” in running the
diagnostic, try rebooting your system from the floppy.
The diagnostic WILL NOT WORK in a “DOS over
Windows” session.
Terminal Mode
If you select either the T or M Terminal Mode option
while running the diagnostic, the diagnostic starts a
simple terminal emulation program. The T option
selects terminal mode at 9600 baud, while the M option
selects terminal mode at the maximum baud rate
supported by your RocketModem model.
1.
If there is more than one RocketModem installed,
you are asked to select a card. Do so.
2. A numbered menu listing the ports on the selected
card displays. You may also press H for help with AT
commands, R to reset a single modem, T to reset all
modems on the selected board, or X to exit.
3. Enter a port number to select a modem. The
Terminal Mode screen displays.
4. Type AT commands to communicate with the
modem.
5. When you are done, press Esc to return to Step 2.
For example, follow these steps to test two modem ports.
This example requires that phone lines be connected to
both Ports 1 and 2.
1. Select Port 1.
2. Enter AT&F0 to initialize the modem to factory
default parameters.
3. Enter ATS0=1 to direct the modem to answer the
phone on the first ring.
4. Press Esc to return to the port menu.
5. Select Port 2.
6. Enter AT&F0 to initialize the second modem.
7. Enter ATDxxx xxxx (where xxx xxxx is the phone
number of the line connected to the first modem).
Watch and wait. The Port 2 modem should dial the
Port 1 modem and you should eventually see the
CONNECT message.
8. Press Esc.
9. Select Port 1. You should see RING and CONNECT
messages.
10. Any keys you press while looking at Port 1 display
when you look at Port 2. Likewise, any keys you
press while looking at Port 2 display when you
return to the Port 1 display.
11. To exit, on either of the ports enter the escape
sequence +++. This enables you to enter ATH to
hang up, or any other valid AT command string.
If you do not hang up, you can return to the still-
active connection by entering ATO.
12. To exit terminal mode and return to the port menu,
press Esc.
Modem Cables
RocketModem ports use standard telephone-type
unshielded twisted-pair cables with RJ11 modular
connectors. These can be purchased anywhere
commercial telephone products are sold.
If you choose to build your own cables, use the following
information. When building cables, use Category 3 (or
better) unshielded twisted-pair wiring.
The connector pinouts are as shown below:
Safety Notices
Installation of inside wire may bring you close to
electrical wire, conduit, terminals and other electrical
facilities. Extreme caution must be used to avoid
electrical shock from such facilities. Avoid contact with
electrical current by following these guidelines:
•
Use tools with insulated handles.
• Do not place telephone wiring or connections in any
conduit, outlet or junction box containing electrical
wiring.
Note: Do not work on your telephone wiring at all if you
wear a pacemaker. Telephone lines carry
electrical current.
• Telephone wiring must be at least 6 feet from bare
power wiring or lightning rods and associated wires,
and at least 6 inches from other wire (antenna
wires, doorbell wires, wires from transformers to
neon signs), steam or hot water pipes, and heating
ducts.
• Before working with existing inside wiring, check all
electrical outlets for a square telephone dial light
transformer and unplug it from the electrical outlet.
