Subject

The GP Gate software now supports the Yokogawa VC100 3G test set. Since the testset
does not support GPIB, a 9 pin RS232 serial cable is used to communicate with the
testset. The serial cable is a female to female null modem cable (pins 2 & 3 cross over).

During the development of the driver for the VC100 we have experienced a “Protocol

Error” message that the testset generates when an unexpected error occurs in the

signaling. This causes the GPGate software to stop and the application needs to be
restarted. Yokogawa has found resolutions to all of the issues which caused this error
condition so far (they are still in the process of implementing one of these resolutions into

their released software). In the event that you experience this “Protocol Error” message,

please contact Yokogawa immediately. They will require the model and software version
of the phone that caused the testset to error.

The VC100s firmware can be upgraded by loading the new testset software (provided by
Yokogawa) onto a USB flash drive and plugging the flash drive into the available USB
port on the front panel of the testset.

Currently, the VC100 only supports 3G Region 1, and is scheduled to support 3G Region
2, 3G Region 3, GSM 850, GSM 900, GSM 1800, and GSM 1900 in December 2004
(this will require a software and hardware upgrade to the current box).
