[amsat-bb] TNC settings for Kenwood TM-D700

Hi all,


Was just wondering if there is anyone out there with any experience setting up a D700 for Packet operation. I do not seem to be able to get my terminal program to speak to the TNC. I can't even get a cmd prompt or any semblance of a connection. It seems to be physically connected fine but still no luck. I have set the baud rate for the port to match the TNC (9600) but am not having any luck. I am just using HyperTerminal. Any ideas?


Thanks
Jordan

Hi Jordan!

Make sure you're using a straight through serial cable (2-2, 3-3, etc).

Then, confirm that the PC and D700 are using the same parameters: 9600
baud, No parity, 8 data bits, 1 stop bit and hardware flow control. If
your settings aren't the same as this, make sure both the PC and D700
agree.

Thanks for your very comprehensive reponse Rich (and everyone else who
replied). All of the settings match and the radio is in packet mode. I am
starting to think that the culprit is the serial cable. I thought it was
straight through but it may not be. I shall do everything you suggest again
but try it with a new serial cable this afternoon.

Thanks for your efforts.


Regards,
Jordan

I just received my TM-D700A also & followed your cable instructions.
When I powered up my 700A I get the following data;
TASCO Radio Modem
AX.25 Level 2 Version 2.0
Release 03/Dec/99 3Chip ver 1.08
Checksum $04
cmd:DA 070327210135
cmd:

Trouble is now it won't accept data when I try to type in the commands.
Have you guys been successful in inputting data from the keyboard.

Hi Bruce and Jordan...

If you're receiving the data from the TNC, but cannot send, it is likely
that you're cable isn't wired for hardware flow control and the D700 isn't
expecting hardware flow control.

You can try software flow control (some software calls it xon/xoff flow
control) or no flow control.

Good point. I keep having to relearn that every time I make a
cable for my D700. It must have pins 7 and 8, RTS,CTS connected
together. Or it wont work... Bob
