ETC Unison DRd Dimming Rack Enclosure - Manual (Page 42)

38 DRd Enclosure Installation Manual
DRd Left I/O Data Termination
The Left I/O board is not included with the DRd enclosure when shipped from the factory.
Instead, the appropriate board is provided in the Paradigm DRd Termination kit or Echo
ACP Network Option kit when ordered separately. The Left I/O board should be installed
by the installing contractor or field technician. Follow the instructions provided with the Left
I/O board for installation and wire termination.
The left I/O board supports the Echo Architectural Control Processor and Paradigm
Architectural Control Processor data terminations including:
• Ethernet on a RJ-45 female connector.
• RS-232 on a male 9 pin (D style) connector (P-ACP only).
• Contact closure input terminations on a 8 pin pluggable connector (P-ACP only).
• Terminations available for 4 inputs and 4 common wires.
• Contact closure output terminations on a 8 pin pluggable connector (P-ACP only).
• Terminations available for 4 normally open relay outputs and 4 common wires.
Connect to Serial RS-232
Integrators or users of advanced systems can interface with the Unison system through the
RS-232 connector on the left I/O board. This connection provides an interface with external
devices capable of sending or receiving RS-232. This connection can also receive serial
commands from a transmitter and provide DRd and system status when queried.
Connect to Ethernet RJ-45
Network interface to the DRd is made through the RJ-45 connector (labeled Ethernet)
located on the left I/O board.
N o t e : Data terminations to the left I/O board are specific to the processor used.
SmartLink does not support a left I/O option.
N o t e : The RS-232 cable (not supplied) should follow common RS-232 pinout for a DB9
receptacle (pin 2 is RS-232 Rx, pin 3 is RS-232 Tx, and pin 5 is ground).
N o t e : All Ethernet terminations must follow IEEE 802.3 and be terminated to the T568B
standard.
