Appendix A.
CABLE DRAWINGS
The EIA-530 standard pinout (provided on the CDM-550T) is becoming more popular in
many applications. However, there are still many occasions when, especially for existing
EIA-422/449 and V.35 users, a conversion must be made.
For these situations, the following two cable drawings show EIA-530 to EIA-422/449
DCE conversion, and EIA-530 to V.35 DCE conversion.
The third drawing shows a standard EIA-232 cable for use with the Remote Control Port
of the Modem. This should also be used for performing Flash Upgrading via an external
PC.
