Microphones and Accessory Connectors

[HarrisonRHW]

2 questions for you guys...

About to do an install where the control head would be mounted on the headliner of a vehicle, and the customer wanted to place the mics on the center console. There is a visual obstruction/entanglement hazard associated with having the mic hang down in front of the windshield. I was planning to just make an adapter to plug the microphones into the accessory connector, and just use panel mount jacks to plug the microphones into the console. I have two questions related to this.

With the Waris series stuff, are there any issues associated with having no mic connected to the front panel? I would disable off-hook PL disable, but I just want to make sure that there are no other potential issues.

Motorola sells a microphone for Spectra/XTL stuff that is listed as weather resistant for motorcycle installs. It appears to have a DB15 connector (or possibly an RS-232 connector) based on photos in the catalog. Can this plug into the rear accessory port of Astro Spectra models or is it strictly for use with the motorcycle remote head data cable?

As usual, thanks for the help.

Let's slow down a bit and see if you can be more specific on just which radio your trying
to put a remote mic onto the rear accessory connector. Also if it is a remote mount
radio, then it would help to know just which head is being used.

On the XTL mobile, the accessory connector depends on if it is a low - medium or a
high power radio. The Spectra mobile also falls into this (I need more info) category.
There are a number of adapter face plates that go on this radio. If you have a
remote mount with a dual DB25 connector, there is no PTT line on the right hand one.
Depending on how this radio is being used, you might be able to move the remote cable
to the right hand connector and use the left one for your remote mic.

There are a bunch of other details that might come into play depending on the radio
and it's configuration.

Like I said, the Mic (that I am inquiring about the RS-232 connector looking mic) is for an Astro Spectra. I am referring to the connector on the back of the mid power radios. Unit is a W5.

The connector on the back of the Astro Spectra is a DB15 female. You should be able
to find all the pin connections on the site www.batlabs.com and then make the selection
for the radio information and then go to the mobiles. Select the Astro Spectra or Spectra
and your pin connection info should be there.

Just remember that there are some software settings that you may have to manage.

Not to mention hardware...the Astro Spectra by default comes with the accessory connector set-up for RS232 modem connectivity. Why on earth Motorola would do that when 99.9% of the radios in the field won't be used for that purpose is beyond me...but I digress. There are surface mount jumpers located on both sides of the command board which need to be moved in order to give you PTT & TX audio inputs on the pins. The exact locations on the board vary depending on the revision.

A search will bring up several threads, here is a couple of them:

Nope.. It's a DA15. (the second character indicates the connector shell size).
With the standard contact arrangements, there are DA15, DB25, DC37, DD50, and DE9.
Other configurations are available (double density, coax, hi voltage, high current)
