1. Program the Call Back Telephone Number in Locations 159 to 174.
2. Select Option 1 and disable Option 2 in Location 180.
3. Program Ring Count in Location 175 as 1 – 13.
The control panel allows a connection of the first call without calling back the remote
computer to make contact. It allows the customer to initiate a modem call by holding down
[6].
Remote Connection with Callback Verification
Remote connect with callback verification offers the highest degree of data security by
incorporating a two-level security check.
The first level is provided because the Installer Code and the Password for A-Link Plus/RSC
must match those of the control panel. The sec level of security exists because the control
panel calls the programmed callback telephone number to establish the valid connection.
To program the control panel for remote connection with callback verification:
1. Program the Call Back Telephone Number in Locations 159 to 174.
2. Select Options 1 and 2 in Location 180.
3. Program Ring Count in Location 175 as 1 – 13.
Answering Machine Bypass Connection
Answering Machine Bypass allows a connection with the control panel for remote control or
Upload/Download when an answering machine or facsimile machine is on the same telephone
line.
To program Answer Machine Bypass Connection:
1. Connect the Modem to the computer.
2. Program A-Link plus Option in location 180 as 1.
3. Program Ring Count in location 175 as 14 or 15.
4. On the A-Link Plus Customer Information screen, select Answer Machine Bypass and set
Modem Dial Time and Dial Interval.
Modem Dial Time is from the start of the first call to the end of the first call. This value sets
the number of rings, noting that one ring is “Ring, Ring – Ring, Ring” and that one ring
represents approximately 5 – 6 sec. Number of rings = Modem Dial Time / 6 (remainder + 1).
Dial Interval is from the end of the first call to the start of the second call.
In A-Link Plus Customer Information screen, when Answer Machine Bypass 1 or 2 is enabled,
A-Link Plus dials two times. Set appropriate Modem Dial Time and Dial Interval for the twice
dialing to establish a successful answering machine bypass connection, preventing the
answering machine or facsimile machine from answering the call. Refer to Ring Count, page
75 for more information on Answering Machine Bypass.
Notice!
Setting or not setting a callback number does not affect Answer Machine Bypass connection.

lines and modems are not required necessary.

1. Connect a B426 or B426-M network module to the control panel using the SDI2 bus.
