Position 8 has no function
SW7 and SW8
These two switches enable the RollCall
network
address to be set. SW7 sets the MSB (most significant
bit) and SW8 sets the LSB (least significant bit)
Both of these switches are used to define the Unit
Address code for the equipment. They are only read
at power-up.
Position ‘0’ on SW7 will disable the RollCall
function
on the unit; all other positions on these switches may
be used to set the Unit Address code in Hex. (SW7 in
the range 1 to f, SW8 in the range 0 to f)
If a code is already in use the RollCall
receive and
transmit LED’s will flash alternately at a 1 second rate.
The unit must then be powered-down, the code reset
and the unit powered-up again.
Note that in a RollCall
segment, all units must have
different unit address codes.
