4.0 General Operation and Special Features
2. Enter the address or slot number—To enter the address or slot number
of the modem to be controlled, press pushbutton 3. If ADDR/C is
displayed on REMOTE screen 2, a screen showing ADDRESS: 000,000 on
the top line will be displayed. If SLOT/C is displayed on REMOTE screen
2, a screen showing SLOT NUMBER: 01 on the top line will be displayed.
Enter the address or slot number as follows: Use the right and left arrow
pushbuttons to go to the digit you want to change. Then use pushbutton
1 to decrease (DEC) a number or pushbutton 3 to increase (INC) it.
If SLOT/C is selected, only modems in the same rack as the controlling
modem may be specified (slots 1–16). However, if ADDR/C is selected,
you can specify any modem in the same rack with the controlling modem
or a remote modem connected to any modem in that rack (Figure 4-1).
The remote modem may be in a rack without a rack controller, or it may
be a standalone modem.
When the address or slot number you want is shown, press ENT. The LCD
will return to REMOTE screen 2.
3. Initiate control—After entering the address or slot number of the modem
to be controlled, select CTRL from REMOTE screen 2. “CTRL” will flash
on and off for about seven seconds until the connection to the specified
modem is made. When the connection is made, all characters on the LCD
of the controlling modem will be in lower case instead of capitals—this
indicates that the screens displayed are for the controlled modem.
Buttons pressed on the front panel of the controlling modem will affect
the controlled modem (and not the controlling modem).
If the specified modem is not present or is not working, the LCD will
display a “NO RESPONSE” message. If a rack controller is not installed
on the rack enclosure or is not working, “CTRL” will continue to flash
on and off indefinitely (until you exit from the address or slot control
mode).
Exiting from Remote Control Mode
To exit from the address or slot control mode, press the ENT button five
times in succession. (If the remote modem resets as a result of a configuration
change, the local modem will appear to have no control. To remedy this
situation, press the ENT button five times.)
