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.
Alarm Output and 4-Wire Audio
Alarm and audio signals are provided on the Alarm or Alarm/Relay module. Refer to Table 6-15
for details on pinout and signal descriptions. Audio signaling and alarm outputs are software
configurable. Refer to Section 5.0 Device Management for more information.
