The LILIN PIH-931D keyboard is designed to work with the LILIN Navigator software.
In order to utilise the PIH-931D keyboard with the Navigator software you will most likely require a USB to RS485 convertor or a USB to RS232 convertor and then an RS232 to RS485 convertor. This will allow you to add an RS485 device to your PC.
For help wiring your PIH-931D please refer to the link below or the document attached at the bottom of this section.
