7720P PROGRAMMING TOOL JUMPER SETTING
7720P programming tool's manufactured before January of 1999 will not work on our new
GSM communication module due to a jumper setting in the device. The symptom to expect is no
power to the 7720P programming tool. The screen will be blank. There is no other symptom for
this particular problem. The Internal jumper will have to be moved before the unit will work on
a GSM radio.
A new version 7720P programming tool (made after January 1999) would have the same
symptoms as well if...
You don't have enough power to support both the GSM module and 7720P programming tool
• Make sure your GSM module has transformer (9VAC 15VA) and backup
battery power (6V 3.1 AH).
Faulty four pin cord
• Make sure your cord is plugged in all the way.
• Try unplugging your tool and plugging it back in.
• Leave your tool plugged in and try powering the GSM module down and then
back up.
• Try reversing your programming cord.
Maybe the internal software of the programming tool is bad
• If all of the above checks do not correct the problem your 7720P programming
tool may have an internal problem and you will need to try a second tool at this
point.
