7.3 RF interface
The GFU30 has a single TNC female connector with impedance of 50 Ohm.
The output power of the transmitter is adjustable between 0.1, 0.2, 0.5 and 1.0 W. The greatest
allowable power depends on limits set by local authorities, which should not be exceeded under
any circumstances. The output power of the transmitter should be set to the smallest possible level,
which still ensures error free connections under variable conditions. Large output power levels
using short connection distances can, in the worst case, cause disturbances to the overall
operation of the system.
NOTE!
Setting the radio data modem output power level to that which exceeds the regulations set
forth by local authorities is strictly forbidden. The setting and/or using of non-approved power
levels may lead to prosecution. Satel and its distributors are not responsible for any illegal use
of its radio equipment, and are not responsible in any way of any claims or penalties arising
from the operation of its radio equipment in ways contradictory to local regulations and/or
requirements and/or laws.

8.2 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
8.3 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.
