NOTE:
For those familiar with device attachment to 9760 systems, a convenient
reference box is provided in the margin that lists the COMMS communication file
parameters for CXTA attachment to a CM9760-CC1. Refer to
Section 3.3 Software

, for additional information.
SECTION I: CXTA OVERVIEW
1.1 DESCRIPTION
The CM9760-CXTA (Coaxitron
®
translator) is a peripheral product of the CM9760 family of
Pelco matrix switches. The previous CXT model interfaced Coaxitron capable receivers with
the 9760 System (P Protocol). The current CXTA unit still supports that function. In addition,
it can be used to interface appropriately configured systems that utilize D protocol for PTZ
control. This allows the CXTA to be used with the DX7000 (Digital Video Recorder) and the
MPT9500 (Transmitter/Controller), as well as the CM9760 system, if desired.
The CM9760-CXTA (Coaxitron translator) obsoletes and replaces previous models of the
Coaxitron translator.

1.3 CONTROL AND RECEIVER OPTION COMPATIBILITY
The current mix of controller and receiver “types” that the CM9760-CXTA can interface is il-
lustrated in Figure 1 below. On the receiver side, note that Intercept
™
and Spectra
®
occur
in the same box separated by an “OR” statement. The “OR” conjunction refers to con-
straints associated with the use of these two receivers on the same translator. The rules
addressing these limitations are discussed in the
BNC Input Grouping
and the
Equipment
Type
subsections in the
Configuration Switch
portion of section

nections – CXTA
