The I/O Terminal Block; Connector Pinout - Axis 250S Blade Installation Manual

6 AXIS 250S Blade - Rack Solution Installation Guide

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)
The Axis Blade Video Servers support several Pan/Tilt device drivers that are available
from the Axis Web site at www.axis.com

Transistor Output 1 With a maximum load of 100mA and
maximum voltage of 24V DC, this output
has an open-collector NPN transistor
with the emitter connected to GND. If it
is to be used with an external relay, a
diode must be connected in parallel with
the load for protection against any volt-
age transients
Digital Input 4 Connect to GND to activate or leave
floating (or unconnected) to deactivate
