How to make your own serial cable to connect PC to CTS-PHD1080P4XS1 a.k.a. Sangam camera


Sometimes it is required to investigate  camera problems by connecting a serial cable from a DB9 PC/MAC serial  port  to the RJ45 camera connector. This article describes the pinouts  used on the camera RJ45 and pinouts used on DB9 PC/MAC side so people  can make their own cable.

DB 9 pin layout

A PC/MAC with a normal DB9 serial connector presenting itself as a DTE is shown in the picture below.


Camera RJ45 pinout

The camera RJ45 pinout can be found in this PDF file. Copy of the layout is below. It shows the normal cable we use to hookup  camera to the codec. The DB9 side of the connector is standard DTE  presentation. The RJ45 side is non standard.


How to make your own cable

Using above information we can build our own cable using RJ45 to DB9 connector wired as follows :

RJ 45                            DB 9
   7     GND           GND         5
   6      TX            RX         2
   3      RX            TX         3
