Connecting Audio Clock Cables in the PDR 100
The procedure that follows describes step by step how to make audio clock cable
connections to the your ASPB in the PDR100. 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 as shown in Figure 13. Follow this rule
throughout the procedure.
Connecting ASPB audio clock cables in the PDR100:
1. To connect the first audio clock cable to the ASPB:
a. Connect one end of an audio clock cable to the ASPB Audio Clock1.
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 15).
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.
(See Detailed Explanation Of ASPB Cabling on page 59.)
2. To connect the second audio clock cable to the ASPB:
a. Connect one end of an audio clock cable to the ASPB 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 or to Channel A of
the video input board in the next higher numbered board slot
(
Ë in example Figure 15). (Remember, if a board has two Channel A
connectors use only one of them.)
3. To connect the third audio clock cable to the ASPB:
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 15) or to
Channel B of the same video input board to which the previous clock
cable was attached. (Remember, if your board has two Channel B
connectors use only one of them as shown in Figure 13 and Figure 15.
