3.10.6 SETTING CALLOUT FUNCTIONS
The callout functions will only have to be set if you want the device connected to the port to dial out through the
RFL 9660. An example of this would be a digital fault recorder (DFR) that would dial up a specific phone number
when a fault is detected. The callout functions include the following:
o Call Out
o Call Request
o Call String
o Call Priority
If the Application Note or device manual indicates that any of these functions should be reset, use the following
procedure; otherwise, go on to the next procedure.
1. Press the [C] and [ENTER] keys.
The following prompt will appear on your display:
Request Enable (Y/N) _
This selection lets you control whether the DTE connected to the port can call out
through the RFL 9660.
2. Press the [Y] key to enable callout requests, or the [N] key to disable it. Once you have entered your
choice, press the [ENTER] key.
3. Press the [B] and [ENTER] keys.
The following prompt will appear on your display:
0 None
1 RTS+DTR
2 DTR+RTS
3 RTS
4 DTR
Enter Mode (0 - 4): _
This selection lets you specify the call request method. This controls how the port
device request lines will request connection to the RFL 9660.
4. Select the call request method you want from the list on the screen, enter the number next to it, and
then press [ENTER].
5. Press the [E] and [ENTER] keys.
The following prompt will appear on your display:
Enter new dialback string (<=40 chars.): _
This selection lets you store a call string for the port. This is a character string containing a telephone
number and modem commands that the port can use to dial out. The following control codes may be
embedded in the callback string:
\H Hang up and pause 30 seconds.
\N Insert a carriage return.
