Mini Usb; Alarm Output And 4-Wire Audio - GE MDS Master Station Technical Manual

Mini USB

The Mini USB port can be used to management the radio through a scriptable command line in-
terface (CLI) using the proper USB drivers available at www.gemds.com. Connect to the man-
agement PC using the included Mini USB Cable. Once the PC registers the device driver, the
port will auto baud. The USB port provides CLI management only and cannot be used for net-
work diagnostics or for payload data.
