COM ports RS-232 and RS-485

The COM Ports RS-232 and RS-485 support several operational modes:

•Generic TCP/IP - enables the video server to receive status/data and send com- mands via TCP/IP

•Generic HTTP - enables the video server to receive status/data and send com- mands via HTTP

•Pan Tilt Zoom (PTZ) - for controlling a PTZ device. A PTZ device requires a driver for its function. Drivers can be obtained from www.axis.com. Please see page 33 for information on how to connect PTZ devices.
