2. Getting Started

2.1 Cable Connection

In order to start operating a TWN4 transponder reader, it simply has to be
connected to a host.
2.2 Power Up
Once a TWN4 reader is connected to the host, it detects the type of
communications cable (USB or RS232), with which it is connected to the
host.
Additionally, the RS232 is sending a version string via RS232 to the host.
2.3 Enumeration (USB Only)
This is only applicable for the USB version: Once the device has been
powered up, it is waiting for completion of the enumeration by the USB host.
As long as the device is not enumerated, it is entering a minimum power
consumption mode, where both LEDs are turned off.
