Switch Settings
There are two switches (SW1 and SW2). Each switch package has 8 individual switches
for a total of 16 switches. See
Figure 54 for details of the individual switch blocks, and
Figure 49 on page 148 for their locations on the transponder PCB.
The primary function of these switches is to set the address of the Model 620x. Each
Model 620x must have a unique address that is also known by the FSA Server. Each
station must have a primary Model 620x. If a station has another Model 620x, then that
one is considered the secondary Model 620x. Primary Model 620xs have addresses that
are less than 512 and secondary Model 620xs have addresses equal to the primary unit
address plus 512. Ten switches are used to select the Model 620x address in binary. Each
address switch in the “ON” position indicates a binary “1” while the “OFF” position
indicates a binary “0”.

Two of the switches on SW1 are associated with the serial port at connector J1. SW1-8 is
used to select the mode of operation for the port, and SW1-7 selects the Software
Configuration Program baud rate. The usual baud rate is 9600 (SW1-7 ON). See the
following table for the descriptions of SW2 and SW1.
