Configuration
The configuration of GFU30 modems is made by using the SATEL Configuration
Manager. Please use GEV171 programming cable to connect the GFU30 modem to the serial
interface of the PC.
SATEL Configuration Manager software and user guide are available on the CD for GFU30
radio modem or from
www.satel.com

Programming
The settings of GFU30 are fully configurable. The most recommendable set-up is GEV171
programming cable, a power supply and the SATEL Configuration Manager software.
Programming can be done in any data speed as long as terminal speed and GFU30 data speed
match.
In Service Mode it is simple to create a connection with a matching data speed. Once the
GFU30 is set to Service Mode GFU30 uses fixed settings 38400 bps, N, 8,1 (data transfer
speed 38400 bps, no parity, 8 data bits and 1 stop bit).
GFU30 will shift into the Service Mode by setting the Lemo connector pin 7 to +12 V. When
using the GEV171 cable this can be accomplished by setting the Prog mode switch to ON
position.
