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.
