IMPORTANT SAFEGUARDS AND WARNINGS
Prior to installation and use of this product, the following WARNINGS should be observed.
1. Installation and servicing should only be done by qualified service personnel and conform to all local codes.
2. Unless the unit is specifically marked as a NEMA Type 3, 3R, 3S, 4, 4X, 6 or 6P enclosure, it is designed for indoor use only and it must not be installed where exposed
to rain and moisture.
3. Only use replacement parts recommended by Pelco.
4. After replacement/repair of this unit’s electrical components, conduct a resistance
measurement between line and exposed parts to verify the exposed parts have not
been connected to line circuitry.
5. If the unit has fuses, replace fuses only with the same type fuses for continued protection against risk of fire.
The product and/or manual may bear the following marks:
This symbol indicates that dangerous voltage constituting a risk of electric shock is

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
Section 3.3 Software
The current mix of controller and receiver “types” that the CM9760-CXTA can interface is illustrated 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 constraints associated with the use of these two receivers on the same translator. The rules
addressing these limitations are discussed in the

SECTION II: CXTA DEFINING CHARACTERISTICS
A number of configuration and connection decisions are made at the CXTA level in order to
interface it with one of three controllers, one of two protocol “flavors” and a large selection
of receiver options. The next section lists connection and configuration options determined
at the CXTA level. For this purpose, the rear view of the CXTA is illustrated in Figure 2.

2.1 CONFIGURATION AND CONNECTIONS–CXTA
2.1.1 POWER
The CM9760-CXTA utilizes a 100V/240V@ 50/60Hz auto-ranging power supply. The external cord connection, power switch and fuse are located on the right side of the unit when
viewed from the rear of the unit. For fuse replacement, refer to Figure 3. A power cord and
Euro-plug adapter are supplied with the unit.

2.1.2 COMMUNICATIONS
The 8-pin, RJ-45 communication input connector located on the rear of the CXTA, and labeled IN, is the data connection to which all controllers must interface. This presents immediate disparities with respect to source (controller) and destination (CXTA) connections that
are spelled out in Table A below:

tivity are answered by means of controller-specific illustrations.
The 8-pin, RJ-45 communication output connector labeled OUT is located next to the input
connector and is used to connect, daisy-chain or cascade two CXTA units together, resulting in 32 ports addressable from one controller port. Not all controllers, however, can utilize
cascading and/or are capable of addressing 32 ports.

, questions related to controller/translator connec-
Pelco Manual C539M-A (12/01) 7
The breakdown, with respect to cascading for each controller, is as follows:
• For the 9760, cascading is allowed; addressing is no problem.
• For the MPT9500, addressing 32 receivers is no problem; it is not, however very prac-
tical as the controller itself is Coaxitron capable. See the remarks made in the
Controller Hookup
• For the DX7000, only 16 receivers at a time are addressable, therefore it can handle
only one attached CXTA unit. This constraint is also necessary because the DX7000
can interface only 16 loop back video inputs.
The data cable that runs between the labeled IN connector on the CXTA and the RJ-45
Sercom port connection located on the rear of the 9760 matrix controller (CM9760-CC1) is
provided. This is a reverse, 8-pin, flat cable (see Figure 4). Since this is the most often encountered configuration, the cable is provided.

Figure 4. Cascading
The provided data cable cannot be used (as is, out of the box) with the DX7000 or the
MPT9500. Each of these has different cabling requirements that are illustrated in the corresponding installation examples (see Figures 15 and 16, respectively).
2.1.3 BNCs
There are 16 pairs (32 total) of BNCs on each unit (see Figure 2). These are IN-OUT,
to-from, dual-function BNCs. The top or bottom row can be used as INPUTS or OUTPUTS.
If the top row of BNCs are used as OUTPUTs, the corresponding BNCs on the bottom row
are used as INPUTs, and vice versa. Characteristics and functions of BNC use are as follows:
• The BNCs are used for video input/output, command/control and in/out looping.
• Receiver access (by controllers) must correspond to the numbered BNC INPUT con-
nector to which the receiver is attached.
• The BNCs are numbered and addressed, left to right, 1-16. The BNCs on a cascaded
translator (the second unit) are addressed and numbered, left to right, 17-32. The address reponse for each controller is set via DIP 1-7 (see Figure 10).

2.1.4 CONFIGURATION SWITCH
The decode of configuration switch functions is indicated in Figure 5 and discussed in detail
in the paragraphs that follow.
This configuration switch configures the translator with respect to the following functions:
1. BNC Input Group (allocated in x8 groupings) and protocol “flavor” (15 or 32 bit Coax-
itron)
2. Choice of P or D protocol.
3. Communications channel baud rate (under P protocol only).
4. Cascade addressing (16/32 channel or translator address range)
5. Type of 32-bit protocol (Intercept or Spectra).
IMPORTANT:
If any x8
group combination is set to
32-bit, DIP switch 1-8 must
be set to restrict equipment
use for the entire translator
to ONLY one equipment
type (receiver): Intercept or
Spectra.
Figure 5. Configuration Switch
NOTE:
Configuration switch positions are read only at power-up time; therefore,
switch changes made after power is applied have no effect until power is recycled.
2.1.4.1 BNC Input Grouping (Receiver Side)
The sixteen BNCs to which Coaxitron receivers are attached are split into x8 groups (1-8
and 9-16). Each group is further defined as entertaining one of two protocol “flavors”: 15- or
32-bit (these are references to 15-bit standard Coaxitron or 32-bit extended Coaxitron, respectively). Therefore, a combination of 15- and 32-bit protocol “flavors” on the same unit is
possible. Conversely, if both x8 groups on the same translator are assigned the same protocol flavor, then the entire translator interfaces only 15-bit or only 32-bit Coaxitron receivers.
