Commands for Serial
Port Control
Change TM-D700A's TNC Mode Remotely via the Serial Port
Thanks for visiting my D700a page. This page is still going strong
after all these years, getting close to 300 visitors a month from all over the
world. I haven't had time to work on this data much over the years, with
family and job obligations, but this information still remains current. If
you have any additional information or corrections for this page, please email
them to me.
Thanks,

The following information was submitted by Steven
S. Dick <ssd@nevets.oau.org>:
I have discovered some additional serial
commands missing from your
page at http://jgav.com/ham/tmd700a.htm
1-7-3 Repeater
REP 1 locked band repeat
REP 2 cross band repeat
1-A-3 Remote control
RC 1 remote control on
These do not require a power cycle to change, but may require other
things to be set first, and enabling either repeater or remote control
disables almost everything else (except disabling them).
menu 1-3-1 programmable VFO (pg 64) (only available in VFO mode)
default values on my radio:
PV 1,00118,00135
PV 2,00136,00199
PV 3,00136,00174
PV 4,00200,00299
PV 5,00300,00399
PV 6,00300,00399
PV 7,00400,00523
PV 8,00400,00469
PV 9,00800,01299
Non menu items (I have more, but here's a few):
AG B,XX set volume (B=0,1 XX=00-3F) (canceled on knob change, not saved)
SQ B,XX set squelch (XX=00-1F) (not sure this is effective)
[note from Jim:] The work I originally did way
back in 2000 only focused on the commands to control settings on the radio via a
computer, that would normally be done on the front panel or microphone buttons.
I never did take the time to experiment with or document the commands to enter
frequencies, channel memory contents, etc. That information should be
easily located with a Google Search. 73 N0RMO

This content was finally put back online thanks
to the generosity of the folks on the
TMD700A Group
at Yahoo. I had lost this information long ago due to a hard drive crash,
and I discovered that someone had archived it at the Group. Thanks to Ken
N5EQT for alerting me to it!
So here is the data, back in its original glory!
Thanks

The following was discovered by Bob Bruninga
about the TMD700A. This will allow his software (and those typing manually) to
command the TNC in the radio to switch between any and all modes without
touching the radio! Here it is, I will be "cleaning it up" and moving it to a
separate page soon, just wanted to share the good news.
I have to thank BOB B for finding the Missing
Link - The Golden Nugget.... how to change to remote control mode when in the
TNC PACKET mode!!! This is the key to making that fabulous all-in-one satellite
ground station with total remote control ability.
Your serial port on
your computer must be 9600,n,8,1. First, enter AI 1 to get the radio to be in
"Command Echo" mode when in radio remote control mode. That way you can see the
LIST data and so forth coming back to you while you are in APRS mode. This
would be handy for an "ALL IN ONE" software program that did memory control,
freq change, packet sending and monitoring, APRS sending and monitoring, etc.
"The Works".
Update 4 Feb 2000:
Some additional experimentation has clarified the control abilities for the
radio - I am now defining four seperate "modes" that the serial port/TNC can be
in: OFF, Radio Control (hereinafter referred to as RC),
APRS, and PACKET. Definitions:
OFF: The TNC is not on, and the
radio will not send/receive data over the air. Note that in this mode the radio
will still accept control commands over the serial port.
RC:
The radio shows on the display TNC PKT (Packet) mode, but the TNC
is not able to actually Tx or Rx data. This is a quick, temporary mode used to
change band or frequency, etc. You would normally then jump right back into
Packet mode to continue receiving data.
APRS:
The radio shows on the display that it is in TNC APRS mode. The radio can Tx/Rx
APRS formatted data on its own without any outside software, like you would
normally do as you drive around using the radio's internal APRS software. Note
that in this mode the radio will still accept control commands over the serial
port to change band, freq., etc.
PACKET: The
radio shows on the display TNC PKT (Packet), and the TNC is at the "cmd:" prompt
like you are used to with most TNCs. You can Tx/Rx AX.25 data with the data
coming out of the serial port - the internal APRS software is not active.
Enter AI 1 (Alpha India space One) while
in OFF, RC, or APRS mode to turn on the "monitoring" feature. This will "echo"
or "return" the control commands for what the radio is doing at the time.
Enter AI 0 (Alpha India space Zero) to turn off this "echo", but the
radio will still accept commands while in this state. However it might be
easier to enter your commands while in AI 1 mode so you can at least get
responses from the radio when you enter your commands.
Update 5 Feb 2000: Another
problem I discovered, which should have been obvious, is that to switch from TNC
PKT (Packet mode) to any other mode, you must remember to drop to cmd: (command
mode) on the TNC if you are in converse mode. It's easy to forget that this is
still a TNC, and if you enter a command while in packet mode, you might end up
having it go out over the air, since your TNC may likely be in CONVERSE mode.
So, remember to send a CTRL-C if necessary! So much to remember and check...
but I will share everything I find if the rest of you do the same!
The following commands should be sent in
UPPERCASE:
TNC/Serial Port

TO GO TO

APRS |
TC 1 then
TNC 1 |
YES |
* Don't forget to send a Ctrl-C
(alt-3 on keypad, hex $03, etc) to get out of converse mode on the TNC if
necessary!
*
You can enter any Radio Control (RC) commands while
in the OFF or APRS modes.
Once in PACKET mode at any time, you may need to
enter HB 1200 or HB 9600 to set the proper packet speed after switching modes.
To switch speed while in APRS mode, use PKSA 0 for 1200, PKSA 1 for 9600.
I tried to make the above chart as clear as
possible, email me if you want to correct something.
Thanks to Bob B as always for his research and
assistance. |
