So I am using a Trimble 4000ssi to do some static work. I have this unit on loan from a friend and colleague.
Anyway, last time I used this unit I had to install Data Transfer on my old desktop computer to download the data via the serial port. I had to add a Trimble 4000 series receiver, accept the defaults and everything worked great.
I used the unit again today and I am unable to get either the AUX or the PWR 2&3 ports to function for data transfer via serial cable. I have the correct download cable for the necessary ports, but I just can't establish a connection.
Does the 4000ssi need to be in a particular mode to transfer data?
I tried restarting the computer, tried both of my com ports on the computer, but to no avail.
If anybody has suggestions on how to get the data connection established please let me know.
P.S. This experience really reminds me how much I love downloading via a USB connection!

You should just need to power up the 4000ssi (power in PWR 2&3 and download cable in PWR - I/O 1). If the download software's port assignment for the serial cable is right, and the comms settings are good, it should recognize the receiver as a connected device. It seems to me that on rare occasions I've had a difficulty downloading from a 4000ssi when the battery was low.
Check the baud rates and other settings on both the 4000ssi and the PC. Some software will use different default settings than the 4000ss is set for.
The Trimble specs for the 4000ssi give maximum rate of 57,600 baud on Port 1.
Thanks Kent! That worked for me.
I really appreciate it.
I always make sure that the receiver has booted to the status screen before attempting to connect from the PC. Failing to do this, as I recall, results in a timeout and may require closing and reopening the transfer application.
You've probably already checked this because it would be so obvious, but is the 4000ssi booting all the way up such that you can control it via its front panel buttons? If not, then it may need its internal 1/2 AA axial solder lead lithium batteries replaced and its firmware reloaded.
