6.2
The RCP-201-01-x utilizes one (1) 15-pin connector for electrical
connections. This connector provides power, data bus control, infrared
input, and three (3) infrared strapping pins for alternate configuration of
infrared digital command codes.
6.3 Standard configuration requires no infrared strap pins to be connected.
Each different type of AI source equipment can be configured to accept
one (1) of four (4) different sets of infrared codes. To change the code
settings, connect one (1) of the strap pins to the strap common (never
connect more than one (1) strap pin to the strap common). Three (3)
strap pins are available to allow the infrared codes to be configured.
6.4
The infrared input provides a ground reference connection (-). For
optimum infrared signal transmission, this ground reference connection
should connect along with the chassis ground reference connection (pin 2)
to the same ground termination location as that of the IFR-9A or IFR-485
module being utilized. If this is not possible, then the infrared ground
reference connection for the RCP-201-01-x shall be made within 12" of the
unit.
