For all switch configurations where the Data I/O is switched internally to the

configuration is used with the SDM-300/-300A Satellite Modems with 25-pin,
34-pin, 37-pin, and 50-pin Data I/O interfaces.

When the RS-301 Remote Switch option is used and the Data I/O is s witched in
a separate unit, refer to Appendix B for installation with RS –301 switch
installed. This configuration is used with the SDM-300/-300A Satellite Modem
with a
100-pin Data I/O (8-channel Mux).
Note: Refer to Appendix C for SDM-2020 cabling instructions to the switch.
