Connecting Audio Clock Cables in the PDR 200/300
The procedure that follows describes step by step how to make audio clock cable
connections to the ASPBs. If you want more detailed information on audio clock
cabling refer to “Detailed Explanation Of ASPB Cabling” on page 59.
NOTE: Before making connections, check to see if any of your video input
boards have two Channel A or two Channel B connectors. (Refer to
Figure 4.) Use only one of the Channel A and one of the Channel B
connectors on these boards. Follow this rule throughout the procedure.
Connecting ASPB1 and ASPB2 audio clock cables:
1. To connect the first audio clock cable to ASPB1:
a. Connect one end of an audio clock cable to the ASPB1 Audio Clock1.
(ASPB1 is the ASPB in the lower numbered slot.)
b. Connect the other end of the cable to Channel A of the video input board
in the lowest numbered slot ( Ê in example Figure 12).
NOTE: Do not connect any audio clock cables to the four channel Composite
Analog Video Output board. These connectors are not used with the ASPB.
2. To connect the second audio clock cable to ASPB1:
a. Connect one end of an audio clock cable to the ASPB1 Audio Clock2.
b. Connect the other end of the cable to Channel B of the same video input
board to which the previous clock cable was attached (
Ë in example
Figure 12) or to Channel A of the video input board in the next higher
numbered board slot. (Remember, if a board has two Channel A
connectors use only one of them as shown by
Ë in Figure 13 on page 48.)
3. To connect the third audio clock cable to ASPB1:
a. Connect one end of an audio clock cable to the ASPB1 Audio Clock3.
b. Connect the other end of the cable to Channel A of the video input board
in the next higher numbered board slot ( Ì in example Figure 12) or to
Channel B of the same video input board to which the previous clock
cable was attached. (Remember, if a board has two Channel B connectors
use only one of them as shown by
Ì in Figure 13 on page 48.)
