Interfacing an IMUX 2000 with an RFL 9700A can be accomplished as follows:
A. Configuration of RFL 9700A:
97A DIG RX: J2: “B” Position
97A DIG TX: J2: “B” Position
B. The configuration of the IMUX 2000 RS-449 Channel Card shall be as follows:
1. DS-562I with MA-406IA I/O
MA-406IA I/O: J2 jumpers in DCE mode
J3 in any position
DS-562I, Switch SW4-2 (Receive Clock Polarity): Normal - ON (Right)
DS-562I, Switch SW4-3 (Transmit Clock Polarity): Normal - ON (Right)
2. DS-562B with MA-406 I/O
MA-406 I/O: No jumpers to set
DS-562B, J1 (Send Timing Clock): Normal - Left (Middle and Front Posts)
DS-562B, J5 (Timing Mode): Internal - UP (Upper and Middle Posts)
