Motorola MTR-2000 pre-emphasized / demphasized settings
Hi all,
I would like to know if the RX and TX audio on the MTR2K Wireline connector is pre-emphasized or de-emphasized according to the configuration of the "Audio" section of the "Channel information" or if it is always de-emphasized / pre-emphasized or always flat.
Considering that our MTR2K will not operate the remote control via Wireline, I would like to know if, after configuring "Remote control type" to "NONE" in the wireline settings, there is any importance of the parameters "Tx notch filter", "Rx notch filter" and HLGT/LLGT frequencies on the audio.
Thank you very much for your help

Jeff, F5BCB

Re: Anyone here familiar with a Zetron model 42 controller?
Also, the last 10 pages of the Model 25 Technical Manual describe that unit's serial port pinout and signals. It might be similar to what the Model 42 has. At least it's a starting point.

Re: Anyone here familiar with a Zetron model 42 controller?
This page:
has some info about a serial port that's close to but slightly different than what was posted above. Maybe it'll work better.

Re: Anyone here familiar with a Zetron model 42 controller?
Mine are next to my BFH, just in-case I shed? a tear or two for the piece of equipment, electronic or otherwise, that I pounded the bejeezus out of to make it work, and it didn't.?
Randy's Rules #1, If it still doesn't work after hours of repair, Hit the thing with a Hammer, if it still doesn't work after that, see Rule #2.
Randy's Rules #2, If it still doesn't work after all that, wack it with? a? bigger hammer, then It's either fixed or F**ked.
(These rules worked very well on CHEAP C.B. Radios and some types of consumer electronics)

Re: Anyone here familiar with a Zetron model 42 controller?
Looks like it is wanting to talk to a modem with the AT commands. May need to simulate one or assert other leads.?

I agree, though it may be a bit OT. An offshoot of many technical people not being good spellers, no doubt.

Yeah, that was a common issue with early Zetron products that were designed prior to any real RS-232 standard existing for DE-9's.? If memory serves, they used pins 3 and 4 instead of 2 and 3 for data.? And I think pin 2 was either +5V
or +12V for powering external equipment.? I forget what ground was...should be able to ohm it out to chassis if nothing else.

Zetron did not use the standard pin out of db-9 connectors. Check in any of their manuals for the pin outs (don’t have a manual handy here now or I’d post it)
