Extending IR and RS-232 Control
➔
rS-232
»
You can use the KD-CATHD300Lite to send RS-232 commands for controlling
remote equipment.
»
Requires the use of a null-modem cable on one (either) side.
➔
ir
»
You may transmit IR information in either direction. The IR input can be from
a dedicated control system or a standard distribution block’s emitter outputs.
Use a fixed 5v input signal with a 3.5mm mono mini jack.
»
The sleeve of the 3.5mm Male connector must have good physical contact
with 3.5 mm Female input/output on the KD-CATHD300Lite.
»
Some 3.5mm Male plugs feature a plastic sleeve that extends longer than an
average sleeve. This may cause poor grounding
contact. See the example to the right of a sleeve
that may cause poor contact.
