3.6 VCR CONTROL SIGNAL OUTPUTS

3.6 VCR CONTROL SIGNAL OUTPUTS

An IRC has up to 32 D9 female output connections numbered J1 to J32, each able to control four VCRs (refer to Figure 6). Every DB9 output supports four IR control cables. Each IR control cable controls the functions of a single VCR.

The wiring for each DB9 output is shown below in Table D.

NOTE: Once installation has been completed, the appropriate program- ming must be made in the 9760 Con- figuration files (ie: SCP/.GPI/.CAM).

3.6.1 Transmitting VCR Commands

Connect an IR control cable to one of the DB9 infrared output connections on the IRC. Run the cable to the target VCR.

For best results in transmitting the VCR commands (play, record, stop, fast for- ward, rewind, pause), the IR LED at the end of the IR control cable must be placed directly over the receiving port on the front of the VCR.
