Probable Resolution #1:

Disable the INS on the Trimble R12i

Before using the base station, disable the INS. Once that is done POSPac will accept the base station file in either the .T04 or RINEX format.

How to disable the INS:

Information extracted from the Trimble R12i user manual, page 43.

Receiver Configuration menu
Use the Receiver Configuration menu to configure such settings as elevation mask and
PDOP mask, the reference station position, the reference station name and code, and to
enable or disable INS.

Probable Resolution #2

Convert the Trimble R12i .T04 file to RINEX

The second option is to convert the .T04 file to RINEX. Once that is done POSPac will accept the base station file.
