A.1 Introduction

The EIA-530 standard pinout provided on the CDM-Qx/QxL is becoming more popular in many applications. However, there
are still occasions, particularly with existing EIA-422/449 and V.35 users, when a conversion must be made.
For situations where such conversions are required, refer to the following table to select the appropriate cable.
In addition, the standard EIA-232 cable used for performing Flash Upgrading is depicted. This cable connects the
CDM-Qx/QxL Remote Control Port to the serial communications port of an external PC.
