RS422 With Non-Isolated Power

The RS422 12V has a maximum power out of 200mA. Pins 2 and 4 receive serial data from an external device,
and Pins 3 and 5 transmit serial data to an external device. RS422 is used for both input and output and has
longer cable distance than RS232.

Installation

This section covers both the Rack Mount and CP2000 Pedestal (optional) installation.

2.5.1 Rack Mount Installation

Before installing Christie ACT in a rack mount, the following should be considered:
Elevated If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may
Operation be greater than room ambient, therefore consideration should be given to installing the equipment in an environment
Ambient compatible with the maximum ambient temperature (ThermoMechanical Analysis) specified by the manufacturer.
Reduce Air Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the
Flow equipment is not compromised.
Mechanical Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven
Loading mechanical loading.
Circuit Consideration should be given to the supply circuit equipment and the effect that overloading of the circuits might
Overloading have on overcurrent protection and supply wiring. Appropriate equipment nameplate ratings should be used when
addressing this concern.
Reliable Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply
Earthing connections other than direct connections to the branch circuit (e.g. use of power strips).
