Serial Com Port Reset
If a Trip-Wire device is installed then it must be removed. Have a new replacement as the removal requires destroying the Trip-Wire.
Connect the RJ45 from the serial cable assembly into the RS232 comm port and the other end into your PC.
From the Toolkit main menu select Device/Select
Select the appropriate com port for your PC. ie COM3
Select the same com Port used by the PC
Cycle power when prompted.
The com port should reset and allow normal operation.
If the com port still doesn’t reset after repeated attempts then the unit should be returned to the manufacturer and reflashed.
