kaysadeya 0 Posted March 26, 2005 As part of an one-going Mad Science Experiment, I bought a used Kalatel/Digiplex KTD-125A PTZ Receiver on Ebay with the hope of getting it to work with my Kodicom KSR 516. As I had feared, my initial tests indicate that this DVR doesn't appear to support the RS-422 protocol used by this receiver. There are multiple variables involved, so I need to address these questions: Does the RS-422 decoder work? There are manual switches for checking the various PTZ operations and all of these test fine on my rusty Pelco PT unit and zoom lens. However, there is still a question on the operation of the decoder portion of the receiver. Does anyone know how to test this? Do I have the DVR configured correctly? The porocedures for setting up and using the PTZ operations are not very clear in the manual, so I'm not sure I've done everything correctly. But the biggest question is: Does the DVR support the correct protocol to communicate with this recevier. The DVR appears to support the following PTZ units: These are listed in the manual: KODICOM KRE-301 RX UNIMO KRX-3200 RX UNIMO KRX-2101 RX NIKO NK-97 SD SAMSUNG SPD-1600 SD SAMSUNG SCC-641 PANASONIC WV-CS854 DONG-YANG DRX-501A SUNG-JIN CCR-20G RX PELCO PELCO-D SD PELCO C1489M-D SD HONEYWELL GC-755 PHILIPS LTC SD TOA (CBC) C-CC554 SD I also found these in the setup menu on the DVR (I don't know the brand names): ITA_MPC1 Vision 360_v1 Fastrax SD SCC-931T DSC-230 Sensormatic SD HD-0670 Commax RX DY-255RXB DY-SPS360DSD CRX-1401 RX CRD-J6416 Yaan SD Does anyone know if the PTZ protocol used by any of these units are the same or similar to that used by the Kalatel/Digiplex KTD-125A? If not, is there are way to locate the code for the receiver and is there a way to input it into the DVR? Share this post Link to post Share on other sites
