422 cable length
on Jul 29, 2008 at 7:02:19 pm

Hi,
I have to install a 422/9-pin cable between my two machine rooms. What would be the maximum length I could use? I think I have 150 feet between both patchbays.

Do you know where I could find a wiring diagram for that purpose because I will have to make the cables myself.

thanks

One thousand feet. 150' is NOTHING for RS422 transmission.

This is the wiring diagram - you need 2 9 pin Male D connectors.
You will wire them PIN TO PIN -
1 -- 1
2 -- 2
3 -- 3
4 -- 4
5 -- 5 (5 is not used)
6 -- 6
7 -- 7
8 -- 8
9 -- 9

Hope you are good with a soldering iron. The easier way is to get a CAT 5 cable, and RJ45-9 pin male adaptors.

If you are running digital video 150', if you don't use good video cable (like Belden 1505A, Gepco VPM-2000 or Canare L-4CFB), your SDI or HD-SDI video signals will never make that distance (if you use cheap crap old RG-59 video cable).

Thanks, it went pretty well. I only damaged one connector before I got it right. Both the SRW-5500 and DVW work fine on 160 feet of RS-422 to the offline station on the other side of the building.

I also installed a 3G ready AVP patchbay. All that's left to install is a RJ-45 patchbay to send the vectorscope/waveform VGA monitor output to the online rooms. I bought 6 eight inch iKan monitors. They work very well for that purpose.

Isn't AVP an amazing company. They are not well known in the US, and it's a little tough to get distribution (compared to ADC and Canare), but their patch bays are FANTASTIC (I like them much better than ADC).

Glad it all worked out for you.
