Pin assignments

Pin assignments for the I/O Connector of the AXIS 291 1U Video Server Rack

Pin Function Description

1 +12V out, 100mA

2GND

3 Channel 1, Configurable I/O 1 Digital input - Connect to GND to

activate, or leave floating (or

unconnected) to deactivate.

Digital output - Uses an open-

drain NFET transistor with the

source connected to GND. If used

with an external relay, a diode

must be connected in parallel

with the load, for protection

against voltage transients.

Min input = - 40V DC

Max input = + 40V DC

Max load = 100mA

Max voltage = + 40V DC
