Trouble Tx'ing APRS packets/mgs with FTM-400 ??

[VK3DQS]

Hello,
Here is the message on screen i receive when trying to transmit a message/packet thru my pc to FTM-400
Any suggestions how to fix?
...........Could not send !
3626.14S/14525.88E-/A=000394PinPointv2.1 to TNC.Error. The write time out

7/03/25 10.05PM Could not send l to TNC.Error:the write timed out

Cheers

I don't have an ftm-400 but it is a communication error

Verify COM Port (check Device Manager if unsure)
Baud Rate: 9600 or 1200 depending on settings (check what baud is being used on the radio)
Ensure KISS mode is enabled if needed.

baud rate was incorrect

baud rate was incorrect on radio , error message is still there but thanks for your tips.

Serial comms can be one of the most frustrating things to debug

I assume this is something that has never worked previously?
Check cable connections, make sure Rx and Tx aren't reversed, check voltages is it TTL or +-12V RS232?

Yes, new connection,hasn't worked before..Can receive from APRSdroid but not from radio to HH.
will check your suggestions Ray thankyou.

Something weird, there are different cables for 1200 baud and 9600 baud. Connects to different pins?
Might be worth checking which cable you have and set baud rates accordingly.

Some more info on this forum might be helpful in identifying which cable.

Yaesu FTM-400 cable capabilities

I bought the original “Yaesu MiniDin10 Cable for Digirig Mobile”. Just to clarify, it does NOT support a 9600 baud connection"??? I thought part of the 10 pin design is that is supports both 1200 & 9600 baud operations in Yaesu radios? That said, I am interested in the CAT control for future...

Ray, you would assume that the 10 pin cable in the box on purchase would suit either baud rate but anyway l will check tonight and let you know

Ray ,FYI ...have changed the baud rate in Pinpoint and on radio with no change..

I still think it's weird that they have different cables for different baudrates, I can only imagine that they are wired different internally, maybe feeding the 9600 baud higher speed data direct into the discriminator direct and bypassing any audio filtering, that might not affect the 1200 baud data.

Do you have an Oscilloscope? Something to look at the Rx Tx lines and see if the data is actually being sent correctly.
Alternatively you could hook if the Tx Line to the Rx line of a serial port on a PC running a terminal program like Terraterm or Hyperterm, or even Putty in serial mode.
