Answer:
Overview
L80 units generate two logs: one when enabling PINPads and one when disabling PINPads. Enabling and disabling PINPads multiple times will cause an L80's log to fill up, resulting in the L80 beeping rapidly and disallowing PINPad activation. To clear the L80's log, use pass-through mode and a Spectrum Pro to communicate with the L80.
If you are using a VP5300 (the Spectrum Pro II with a silver bezel), consult this guide instead: Clearing the Log Files in an L80 Using a VP5300.
Before You Begin
Download and install the latest version of uDemo: uDemo (USDK_DEMO)
Clearing Logs
Connect your L80 to the Spectrum Pro and connect the Spectrum Pro to the PC running uDemo. Make sure the L80 is connected and in awake mode for the following:
- In uDemo, under the Device tab, select Send Data Command option in the commands list.
- The results window should display Send Command Response ASCII: ?'F ??.
- To clear the L80's log files, enter the command 78 52 01 51 and select Execute Command.
The results window should display the response from the log file dump. If you receive a "Send Command Fail Error Code: 0x3: time out for task or CMD" response, make sure your L80 is powered on and awake.
