Wiring diagram for 9-pin RS-422 to RS-422 cable?
Hi folks,
Please can some kind soul point me in the direction of a diagram showing me how to put together an RS-422 to RS-422 cable (9pins at both ends) for controlling a DigiBeta deck from my Decklink HD Extreme card? I've searched the web for ages but there seems to be a lot of contradicting information out there. Many thanks, Jack |

Rs422
Normally the basic pins that are a must are:
Pin 2 TX or RX based on gender of the connector Pin 3 TX or RX based on gender of the connector and Pin 5 shield. Depending on specific equipment there are other pins that might be used, but for the most part these 3 being connected properly will get you basic control. |

Why not just spend a couple of bucks and buy an RS-422 cable?

Hi Jack.....
Could this be what you're after?
http://www.interfacebus.com/Design_C...IA449_Bus.html The "449" is the specification for using 422 differential driver/ receiver pairs with a 9 pin connector. Hope this helps. CS |
