Remote Programming

Connecting to the SVMi-8 system via the modem allows a remote administrator to monitor and provide routine
administration without having to be on site.
Connect an analog line to the modem line jack of the modem and connect the modem to the SVMi-8 serial port with
a 90-pin female connector.
The Cable
For the cable between the SVMi-8 serial port and the modem, the pin configuration should be a straight-through
cable with TXD and RXD wires crossed. This would be pins 3 and 2 respectively on the 9-pin connector, or pins 2
and 3 on the 25-pin connector.
To make this cable, start with the standard cable that comes with your modem. This will be a straight through cable,
because the cable design assumes that the SVMi-8 COM port uses pin 2 for RXD and pin 3 for TXD, when in fact
they are reversed.
To adjust for this, you must cross pins 2 and 3 in the modem cable. The easiest way to do this is use a null modem
adapter on one end of the cable.
Note that straight-through 9-pin to 25-pin cable does not mean pin 1 to pin 1, pin 4 to pin 4, pin 5 to pin 5, etc. The
pin assignments on a 9-pin connector are different than the pin assignments on a 25-pin connector.
To avoid dedicated line charges, you can connect the modem to a single line port from the phone system and use the
auto attendant to direct your call to the modem.
