GU01 GPIB to UART Module is a GPIB device interface to UART adapter module. It is designed for equipment. If you have a UART port on your system and you would like your system to be controlled by GPIB controller, then this is for you. The module can be Listener and talker, not controller.
GU02 is similar with GU01 GPIB to UART Module but it is a compact design. It has only one UART port on the module(GU01 has two UART ports on the module). It is also designed for equipment.If you have a UART port on your system and you would like your system to be controlled by GPIB controller, then this is for you. The module can be Listener and talker, not controller.
