Pelco CM9760-CXTA - Manual

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 fileparameters for CXTA attachment to a CM9760-CC1. Refer to Section 3.3 Software Considerations , for additional in...

Pelco Manual C539M-A (12/01) 7 SECTION II: CXTA DEFINING CHARACTERISTICS A number of configuration and connection decisions are made at the CXTA level in order tointerface it with one of three controllers, one of two protocol “flavors” and a large selectionof receiver options. The next section lists...

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 Coaxitr...

12 Pelco Manual C539M-A (12/01) SECTION III: CXTA INSTALLATION 3.1 MOUNTING THE CXTA Installation of the CM9760-CXTA translator is relatively simple (refer to Figure 12). It is rackmountable in a standard 19-inch (48.26 cm) rack, using only one RU of vertical rack space.Once the unit is physically m...

Pelco Manual C539M-A (12/01) 13 3.2.2 9760 SYSTEM HOOKUP (P Protocol) Two possibilities are: 1. Single or multiple translators hooked to unique Sercom ports on a system matrixswitch, or 2. Item (1) with the addition of cascaded translators added to the mix. The second possibility (item 2) encompasse...

Pelco Manual C539M-A (12/01) 19 3.3 SOFTWARE CONSIDERATIONS Despite the considerations given in this section to highlight aspects of required softwaresetup, there is no substitute for consulting the respective manuals for both the controllerchosen and for the receiver to be used. You must take care ...

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. 3.3.3 MPT9500 TRANSMITTER/CONTROLL...

Pelco Manual C539M-A (12/01) 21 SECTION IV: CXTA OPERATION 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 configurationsettings in internal RAM. Subsequent protocol-spec...

22 Pelco Manual C539M-A (12/01) SECTION V: APPENDIX 5.1 COMMUNICATION PARAMETERS There is only one basic set of signal interface rules that you must consider when wiring two9760 communication devices together. Those rules are given in step 3 below. Frustration arises only if the information you are ...

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 endof 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. Straight cable is u...

24 Pelco Manual C539M-A (12/01) 5.2 CABLE PARAMETERS Data communication cables are used in the CM9760 system to connect required equipment toappropriate 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, f...
