IMUX 2000 DS-562NC RS-449 INTERFACING
WITH OTHER RFL PRODUCTS
This section describes timing configuration settings when interfacing the IMUX 2000 DS-562NC
with other RFL products using RS-449 communications. The IMUX 2000 DS-562NC can be
interfaced with the RFL 9300, RFL 9700, RFL 9700A, RFL 9720 and RFL 9745. It is highly
recommended that clock and data transitions are confirmed with a scope to insure proper system
operation.
IMUX 2000 DS-562NC AND RFL 9300 (RS-449, RS-530)
Interfacing an IMUX 2000 DS-562NC with an RFL 9300 can be accomplished as follows:
A. The programmable jumpers on the 9300 Direct Digital I/O module shall be positioned as follows:
J2 (Send Timing): “A” Position
J3 (Receive Timing): “A” Position
B. The configuration of the IMUX 2000 RS-449 Channel Card shall be as follows:
1. DS-562NC with MA-406IA I/O
MA-406IA I/O: J2 jumpers in DCE mode
J3 in any position
DS-562NC, Switch SW6-5 (Receive Clock Polarity): Normal - OFF (DOWN)
DS-562NC, Switch SW6-7 (Transmit Clock Polarity): Normal - OFF (DOWN)
2. DS-562NC with MA-600 short haul fiber I/O
MA-600 I/O: No jumpers to set
DS-562NC, Switch SW6-5 (Receive Clock Polarity): Normal - OFF (DOWN)
DS-562NC, Switch SW6-7 (Transmit Clock Polarity): Normal - OFF (DOWN)
C. Confirm Clock and Data Transitions to Insure Proper System Operation as follows:
1. RFL 9300 CCM: The positive edge of the RxClock (TP5) must be in the center of the
RxData bit (TP4).
2. IMUX 2000: DS-562NC - The positive edge of the TxClock (TP16) must be in the
center of the TxData bit (TP15).
