Setting up a Modem Environment

VPort 2140 Video Server provides 2 modem modes: Modem and Null Modem. The null modem mode can be used for point-to-point connections in a local environment. Although the baud rate can be set up to 115.2 Kbps, the actual data rate depends on the Modem connection. For dial-up connections, the VPort 2140 Video Server waits passively for a phone call to establish a point-to-point connection.

The Modem and Null Modem dial-up connections are for initial usage of Video Server. If you have already used an Ethernet connection, reset Video Server to factory defaults before using a dial-up connection. In addition, when using a dial-up connection, the Ethernet socket must be disconnected.

The Modem and Null Modem connections for VPort 2140 Video Server only support the dial-in function, which means that you can access the VPort 2140 Video Server, but VPort 2140 Video Server cannot send alarm messages to you automatically via the Modem and Null Modem connection.
