Pelco Manual C539M-A (12/01) 5 IMPOR T ANT SAFEGUARDS AND W ARNINGS Prior to installation and use of this product, the following W ARNINGS should be observed. 1. Installation and servicing should only be done by qualified service personnel and con- form to all local codes.
6 Pelco Manual C539M-A (12/01) 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 CXT A attachment to a CM9760-CC1. Refer to Section 3.
Pelco Manual C539M-A (12/01) 7 SECTION II: CXT A DEFINING CHARACTERISTICS A number of configuration and connection decisions are made at the CXT A level in order to interface it with one of three controllers, one of two protocol “flavors” and a large selection of receiver options.
8 Pelco Manual C539M-A (12/01) 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.
Pelco Manual C539M-A (12/01) 9 2.1.4 CONFIGURA TION 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.
10 Pelco Manual C539M-A (12/01) 2.1.4.2 Protocol T ype This bit is set to correspond to the protocol input of the associated controller (see Figure 7). Figure 7. Protocol T ype 2.1.4.3 Unused DIP Switch DIP switch position 1-4 is not used but is reserved for future use.
Pelco Manual C539M-A (12/01) 11 2.1.4.5 Channel or Address Select If DIP 1-7 is set to the OFF position, the translator responds to addresses 1-16. If DIP 1-7 is ON, the translator responds to addresses 17-32.
12 Pelco Manual C539M-A (12/01) SECTION III: CXT A INST ALLA TION 3.1 MOUNTING THE CXT A Installation of the CM9760-CXT A translator is relatively simple (refer to Figure 12). It is rack mountable in a standard 19-inch (48.26 cm) rack, using only one RU of vertical rack space.
Pelco Manual C539M-A (12/01) 13 3.2.2 9760 SYSTEM HOOKUP (P Protocol) T wo possibilities are: 1. Single or multiple translators hooked to unique Sercom ports on a system matrix switch, or 2. Item (1) with the addition of cascaded translators added to the mix.
14 Pelco Manual C539M-A (12/01) Flowchart 1. Installation Decision T ree The following flowchart might prove helpful as an aide in configuring the different systems mentioned above with CXT A translator(s). The flowchart does not include direct mode using the CM9760-KBD.

Pelco Manual C539M-A (12/01) 19 3.3 SOFTW ARE CONSIDERA TIONS Despite the considerations given in this section to highlight aspects of required software setup, there is no substitute for consulting the respective manuals for both the controller chosen and for the receiver to be used.
20 Pelco Manual C539M-A (12/01) 3.3.2 CM9760-KBD DIRECT MODE Consult the required manuals for setting up direct mode operation. The KBD manual (C540M) is the most important. In particular , see section 3.2.7 Direct Camera Control/Serial Port Speeds in the KBD manual.
Pelco Manual C539M-A (12/01) 21 SECTION IV : CXT A OPERA TION 4.1 POWER-UP At power up, the system microcontroller reads the configuration switch, dip switch posi- tions, sets up the internal UART with the requested baud rate and stores the configuration settings in internal RAM.
22 Pelco Manual C539M-A (12/01) SECTION V : APPENDIX 5.1 COMMUNICA TION P ARAMETERS There is only one basic set of signal interface rules that you must consider when wiring two 9760 communication devices together . Those rules are given in step 3 below .
Pelco Manual C539M-A (12/01) 23 If a cable is “straight”, then pin 1 at one end of the cable goes to pin 1 at the opposite end of the cable. If the connecting plugs on this cable interface two devices, then pin 1 on de- vice one would physically be connected to pin 1 on device two.
24 Pelco Manual C539M-A (12/01) 5.2 CABLE P ARAMETERS Data communication cables are used in the CM9760 system to connect required equipment to appropriate data communication ports on the CC1, which are either RS-232 or RS-422 driven. The characteristics of the cable chosen (if not supplied) depends, first of all, on the driver type it interfaces.
Pelco Manual C539M-A (12/01) 25 Most of the time, connection cables are supplied with the device. As long as the supplied cable is appropriate, no problem arises. If the cable length needed is greater than that sup- plied, a problem arises for the installer/specifier as to the type of cable to use.
26 Pelco Manual C539M-A (12/01) Although the communication link can be as far away as 4,000 feet (1,220 m) (per Figure 20), this is theoretical. Pelco recommends that for distances greater than 2,000 feet (610 m) a CM9505UPS-422 power supply , with data repeater, be used.
