The Firmware Wizard reports an
error when I attempt to upload
firmware.
The I/O or Voice Interface unit
loses its programming every time
the power is cycled.
The Voice Interface doesn't answer
incoming calls.
If the wizard completed all three
upload sections and the Remote /
Local LED is on, the firmware
uploaded successfully but Lynx is
unable to reset the unit.
The wrong PC COM port is
specified in the Firmware Wizard.
You are connecting your computer
to the wrong COM port on the
GSC3000 I/O or VRC2500 unit.
You are using the wrong cable to
connect to your unit.
The JP9 or JP1 jumper is engaged.
There is memory failure.
The phone line is not connected or
it is connected to the wrong jack
on the Voice Interface.
The Voice Interface firmware needs
to be cleared and reloaded.
The unit took a voltage surge that
overloaded the onboard
protection.
With the power on, engage the JP9
jumper to clear the memory (see
Appendix A). Then disengage the
jumper and try connecting. If the
connection does not succeed, retry
the firmware upload.
Make sure the COM port setting in
the Firmware Wizard matches the
COM port you are using to
connect to your unit.
See Appendix A: Uploading
Firmware for the correct port
connections.
Use the supplied null modem cable.
For normal I/O unit operation, the
JP9 jumper should be connected to
one pin only (for a Voice Interface,
the jumper is at JP1). Verify that
the jumper is connected correctly
(see the diagram in Appendix A).
Contact Burk Technology customer
support.
Use a telephone set to verify the
line you are using is functional.
Then make sure to connect the
phone cord to the LINE jack on the
Voice Interface or VRC2500.
Engage the JP1 jumper and power
cycle the unit (see Appendix A).
Remove the jumper and use the
Firmware Wizard to upload new
firmware.
Contact Burk Technology customer
support.
