The I/O Terminal Block

Axis Blade Video Servers connect to an I/O terminal block used for transmitting data over
multi-drop communication lines:
• RS-485 Pan Tilt devices
• RS-232 Pan/Tilt devices
• External triggering (typically associated with CCTV equipment) COM1 is internally multiplexed
with the RS-485 port via the Terminal Block Connector. COM2 can also be used for connecting
a modem or the AXIS 2191 Audio Module.
The Axis Blade Video Servers support several Pan Tilt device drivers that are selected from
the Administration Tools in the video server's internal web pages. Please see
www.axis.com for a complete list of supported devices.
