XTVA Transportable Base Station

[harley-birdman]

Hello everyone....I'm new to the forum and would like to say how impressed I am on the knowledge and set up of the forum. I found this board a couple days ago on a google search for the XTVA and probably spent a good 10 hours reading different posts of interest. So thank you for the information.
But what brought me here was some information on the XTVA. I've been tasked with removing the XTS Vehicular Adapter from the Transportable Base Station 'briefcase' and installing it in a vehicle. Everythings going good during the bench testing.....power hooked up good....antenna went fine with mini UHF.
Now the only problem is, I have no audio.
I tried everything...well, pushed every button on the radio and hand held mic and checked the menu's....nothing will work.
Now, the external speaker in the briefcase goes through the 25 pin Interface Connector....so I removed the connector and plugged it in. With the external speaker wires I touched some of the connector pins and all of a sudden we had audio coming from the internal radio speaker. I qued it repeatly and it all worked great. So I removed the connector, the radio from the adapter and disconnected power.....after reconnecting everything......no audio again...ugggg....??? Tried all the steps previously mentioned.....and no love. I'm thinking I shorted something in the 25 pin connector to avtivate the internal speaker.
Looking at this article at http://www.batlabs.com/xtva.html it shows different shorting procedures to activate different functions, but none for audio.
Has anyone gone through this install before?
Anybody have any idea's to try?
Also, since XTS was installed in the base station it didn't come with any proper wire harness'....does anyone know where to get the power harness and speaker harness for them?

Any help will be highly appreciated.
Thank you,
Randy

I do not know anything about the device you removed the xtva from - but go to the web page below and look at the speaker conn pinout list.

http://batlabs.com/xtva.html

Each xtva comes with a HSN1006A Amplified Speaker and a HKN6455A Speaker Interconnect Cable.

Comming out of the xtva pins 3 & 6 get shorted - this transfers the audio to the xtva amplified speaker and mutes the xts speaker.

Hopefully this should get you going. Good luck and post back if this does not do it for you(or even if it does).

EDIT: The interconnect cable molex connector on the xtva end has the short for pins 3 & 6. On the amplified speaker end
there is another molex connector to plug into the speaker and there is also a short in the molex conn on that end but I do
not know what that one is for.

Since when do XTVAs come with a speaker?

Since when do XTVAs come with a speaker?

Sorry about that - thats how we order them. I can not see purchasing an xtva without an amplified speaker
in a high noise environment(mobile operation).

ok I was a little worried there, recently sold a handful of these things and ordered the speakers separately....glad I didn't miss out on a free speaker

Randy,

The XTVA that is installed in the Transportable Base is a special version of the XTVA which is missing the volume knob which is normally located next to the two LED's which means that you have to use the HHCH to control the volume. The audio is routed out of the XTVA on the 25pin connector to a circuit board which is an audio amplifier. In the standard configuration the XTVA is connected via the 6 pin molex connector to an external speaker with the audio amplifier built into the speaker ( hsn1000 I think??? Mostar speaker). There is also a jumper that must be in place on the molex connector to route audio to the external speaker. I hope this helps.....

I think your going to find a few hurdles installing that and getting it to work easily. You won't be able to adjust volume without the HHCH, I am also skeptical about it working outside the environment it was designed for, i.e. the Zero case it is in. IIRC, the XTVA has a different firmware set, and it missing parts, i.e. a volume knob for starters. I have had a few of these in the shop, kinda perused over them and thought...... another SP project.

Good luck, let us know if you get it going. If you need one that is intended fr use outside of the case, I have one, maybe we can do some horsetrading.
