Tm-d710g manual query

bobsayers2000
 

Hi, All, 

I'm returning to APRS again after a break of a few years and trying to get to grips again with the amazing range of features and commands of the 710.

I'm doubtful if I shall use Packet again (any input from UK hams on the level of activity would be very useful) but am trying to understand an anomaly in the documentation.

Page 39 of the "basic" manual shows a serial cable connected from the PC port on the main radio unit to the serial port of a PC.

However, page PACKET-1 of the more detailed manual says "do not connect a computer to the PC terminal of the TX/RX unit" .

Or does this latter sentence mean not to connect in this way when there is also a connection to the PC from the DATA port to the PC?

Best regards, 

Bob, G8IYK
North Norfolk.

Wow, I figured it out.  Occam's Razor applied to Murphy's Law.  So I said to myself, "It's the cable stupid! "  Sure enough, using a new cable resolved the issue.  I can only assume that hardware flow control was shot and the data flow overran the buffer. I could not test the theory  as the lowest baud available was 9600 at the computer. So, this issue was a bad cable .Both cables we're FTDI, same driver.   Thanks for the input!

Re: GPS question

Depends on the version of the 710 you have.  The 710 does not have built in GPS.  This You will have to use a hockey puck type.   Byonics.com has them at a reasonable price.  Green Heron Labs used to sell a GPS that attached to the control head.  There also was a ham that sold a GPS to attach to the head.  The last option is to purchase a GPS module and install it in the Control head.  Directions are on the web.  

The 710G has  a GPS built into the control head.

Hi,
     The TM-D710 does not have a GPS built into it,   the TM-D710GA does have a GPS built into it.    You can plug an external gps into both models.

Thanks Jess..I am plugged into the com port on the head.  So I get GPS data in TNC mode fbut I did switch from APRS to TNC so possibly some GPS data in a buffer.

Are you by any chance plugged into the gps port (the little headphone jack looking one on the side)? The com port on the back of the heqd is what you want.

Re: TNC ERROR - D710GA

I received my Tm-d710ga back from Kenwood yesterday. $75 labor, $10.34 for the 2 batteries,  $19 return shipping costs.  Hmm, spent about $45 to ship it out there initially (w insurance), so about $150 overall in expenses.

The culprit was indeed the batteries (2) in the control head.

Re: TNC ERROR - D710GA

Dennis Yard
 

I had the same issue with my then new (3 years ago) D710G and had to send it back three times before the service dept finally came to the conclusion that the battery holder had a bad solder joint.   Its worked fine since that was fixed.

My 18 month old Kenwood TM-D710GA radio "decided" this past week that it didn't want to work in APRS12 TNC or PACKET TNC anymore.

I had never gotten around to using this radio in digital modes until I was getting ready for a large Ultra Run this weekend with nearly 1,000 runners.  We use RMS Express / Winlink packet to send CVS files (with runner bib numbers, times in & out) from 5 check points to net control.

I was able to get my TM-D700A working with 2 different cables (Null modem serial & RT Systems USB). But the RT Systems USB cable for the TM-D710GA appeared not to be working.  I wanted 2 radios working in case one failed. Redundancy. 2 laptops, 2 radios, 2 power supplies,  2 antennas, well you got my point.

So I bought another USB Data cable on eBay that turned out to be very similar to the RT Systems cable. It didn't work either.

Then suddenly the control head display started showing "TNC ERROR" any time I entered APRS or PACKET modes after status of "initializing TNC."

So, after trying a full reset at Kenwood tech support's advice, they asked me to send it in for repair.  They'll get it next Wednesday and we'll see what happens.

BTW, the run got relocated because of rainy weather affecting the trails and we're not going to be involved at the new location 150 miles west of here.  Oh well!

Thank you, Mike.  I've already shipped it off to Kenwood for evaluation and repair, so hopefully it will be inexpensive. But I will bookmark that website vendor just in case.

One cause of TNC Error message is a dead battery (very small ML-614) in the control head. Sometimes removing the battery for some period of time and replacing it will clear the error. If the battery is truly dead and will not take or hold a charge it will come back at some point.

What are the recommendations for APRS map display with the 710G?

Re: 710 head connection cable

Larry Sampas
 

I have used a 5-foot straight-through UTP ethernet cable for years on a TM-D710A and for several months on a TM-D710G. A network tester shows the factory-supplied cable for the TM-D710G  is a straight-through unshielded cable. 

 Prior to that, I tried an ethernet coupler (RJ-45) and had an issue where APRS beacons would transmit on the other side. e.g. APRS set up on the A band and would TX on the B band. I reviewed my config, and everything looked correct, so I swapped the cable. I didn't have any more issues after that.
