Overview

The EIA-530 standard pinout provided on the CDM-425 Advanced Satellite Modem is becoming more popular in many applications.
However, there are still many occasions – especially for existing EIA-422/449 and V.35 users – when a conversion is required. For these
situations:
Figure A-1 depicts the cable required for EIA-530 -to- EIA-422/449 DCE conversion.
Figure A-2 depicts the cable required for EIA-530 -to- V.35 DCE conversion.
Figure A-3 depicts a standard EIA-232 cable for connection between the CDM-425 Advanced Satellite Modem Rear Panel
Remote Control port and any serial port on the User PC.
1. The Electronic Industries Association (EIA) designations supersede the Recommended Standard (RS)
designations. References to the old designations may be shown when depicting actual text (e.g., RS-232)
displayed on Web Server pages, serial remote interfaces, Telnet Command Line Interfaces (CLIs), or unit rear
panels. All other references in the manual refer to EIA designations.
2. All dimensions, where specified in the illustrations featured in this appendix, are in inches.
