L100 Pass-Through Mode

On some products, the L100 Pinpad interfaces directly with the unit. Normally, the L100 would be controlled by the NEOII device as needed, for example, collecting a PIN during an EMV transaction. But there may be instances where sending direct commands to the L100 is required by the integrator. For this, we have a L100 Pass-Through Mode.

Enabling L100 Pass-Through Mode
Pass a value to TRUE to IDTechSDK::IDT_NEO2::device_enablePassThrough()
You then send IDT_L100.SharedController commands according to the commands available in the IDT_L100 class. For example, to reboot device, you send:
IDT_L100.SharedController.rebootDevice();
Disabling L100 Pass-Through Mode
Pass a value to FALSE to IDTechSDK::IDT_NEO2::device_enablePassThrough()
You now resume sending all commands to the IDT_NEO2.SharedController
