Bowman Marconi Selex H4855 PRC-343 connection

[DutchieD32M]

Hello everyone, I am hoping there is someone that can help me out with this dilemma.

I am soon receiving a Bowman/Marconi?Selex (take your pick) H4855 Prc-343 Personal Role Radio. There seems to be a lack of information on this unit on the internet that is useful for someone that has not been able to made himself familiar with this unit. There is no user guide or manual to be found, nor any reasonable how-to's. My problem is as follows:

I am getting a dual PTT version and I would like to connect it to a secondary radio (PRM446). Will I have to fashion my own connector cable of some sorts? (usually other commercial radios dont come with LEMO connectors). I will probably be looking at a Kenwood or Motorola connector. If I do have to make my own cable, does anyone have a schematic of the H4855's pin wiring?

Other question: who has a manual?

And on a final note: how in darn-it's name do I program this thing...? Hmm, maybe with the answer provided to my question above



NB: since there are so many topics, I kind of got lost to where this thread belongs, so moderators and admins, feel free to move this post around as you see fit and accept my apologies.

70 people look at it and no one has anything to say? Can't believe my luck...

Something like manual

Hi Dude,
If you are still looking for some data, Take a look on this site : Bowman - H4855 - PRC-343 - Personal Role Radio That is all what i have found about it.

P.S. If you are still here. Where did you bought it and how much did you paid for it.

Regards !

I have since found the information needed, also with help from the above website and other sources. I bought it for 130 euros from a friend who was a dutch KCT operative.

First I saw this thread, I have several single and dual PTT versions and am familiar with the radios if you need more info.

Well, I am looking to connect my dual PRR to a secundary radio, probably a PMR 44 type, so if you have any information on the connector that runs out of the dual ptt module, that would be appreciated, i.e. what is the name of the connector, are there any impedence requirements etcetera. I have already found a picture telling what each pin is (if it is correct).

I think the extra connector on the bottom of the duall PTT is for connection to a vehicular repeater/retrans.
Here is a link to info with details on pinouts: Bowman - H4855 - PRC-343 - Personal Role Radio

so how in fact does one go about connecting a secondary radio to the dual PTT? I have seen pictures of units connected to other radios using this bottom connector, but that might as well have been in error. If the bottom connector is just to connect to a repeater, must the secondary (command net) radio be connected to the 5 pin lemo connector on the top as well?
