a Warning
The Personnel Alert Base Station must be
powered down before removing the outer
cover. If it is in a classified area, either remove
the base or declassify area.
MODBUS Switch Configuration
There are two sets of dip switches (S1 and S2) on the main
board to set the MODBUS configuration. These dip switch
settings are loaded only upon start-up. If changes are
required, the base station must be powered down.
Note
Ensure that each unit has its own unique address.
Figure 13. S1 and S2 Dip Switches for

Address 0 is forbidden. A minimum of one switch must be in
the 1 position. Valid addresses range from 1-255.
Set the Address Dip Switches
Note
Switches for A7, A6, A5, A4, A3, A2, A1, and A0 set the
local address of the Personnel Alert. An address is selected
by setting the binary equivalent of the address of the dip
switches, where A0 is the least significant bit.
The Personnel Alert is set to address 01 as the
default.
