Contents of the SS900FH package 

 

The package contains the following: 1- SS900FH, 1 - 18VDC Power Supply, 1- Manual and 1 Quick Start Guide.  
If ordered, there will be the reverse polarity SMA connector antenna. 
For antenna and power options please contact GDI Communications Technical Support. 

Configuration Switches 

As of the printing of this document, 232/422 is the only switch that is operational.  All other switches are 
non-functioning. 

 
 
 
 
 
 

 

Host/Controller Connections: 

 
The SS900FH comes from the factory configured for 

9600

 baud, 

8

 data bits, 

n

o parity and 

1

 stop bit. 

Other configurations can be programmed using either a terminal emulation program or the “GDI SS900FH.exe” 
program.  Host/Controller connection is made through the DB9 connector located on the rear panel.
