Description

The GBS-USBR1 allows a PC or Apple Mac to control a single external device using a relay contact attached to the USB port.

Simple for the programmer to use, the GBS-USBR1 appears as an additional COM port (network port on the Apple Mac) and can be easily interfaced into your code.
The relay is controlled by issuing commands to the port as if it was connected to a conventional serial (or network on the Mac) port. No technical knowledge of USB is required, and no new driver interfaces need to be learnt.
The GBS-USBR1 is available as an OEM PCB or in an enclosure and is supplied with a USB and external power cable. Volume pricing available.

Device drivers and full documentation are available on-line. Additional options for configuration include some additional digital I/O and choices for communications protocols/command sets which can be adapted for specialist uses. In addition a legacy serial based device could be directly replaced by the GBS-USBR1 without having to change existing software.
