2.8.2 RS485 Serial Network - Address
Switches and Termination
Resistors
The RS485 network is connected to the
Termination Board as shown in
The following must be set during configuration:
a. The IDR repeater address; this is set in the
range 1 to 31 in binary by using the first 5
switches (A) on the Control Board (address
0 - all switches set to 0 - sets the repeater
for ‘listen only’ and must only be used during
commissioning). The decode is given
below. Switch 6 must be set to 0 (it is set to
1 in applications which use addresses
above 31).
Note:
If the IDR repeater is used with an ID50
fire control panel, the address must be
set in the range 1 to 16.
b. Switch 7 must be set according to the type
of connection used by the
repeater
, in this
case 0 for RS485 (does not have to be the
same as in (c) below).
c. Set switch 8 according to the type of
network used by the
fire panel
; set to 0 if
an RS485 network (i.e. Master/Slave) is
used, or to 1 if an ID
2
net network is used.
d. If the IDR repeater is at either end of the
RS485 network, TERM ON jumpers JP2/
4/6 (B) on the Control Board must be fitted
to put the line termination resistors in circuit.
If the IDR repeater is not at either end of
the network, these jumpers must not be
fitted (the link supplied on the Control Board
should be placed across TERM OFF
jumpers JP1/3/5).
The IDR repeater must be associated with the
fire control panel it is to repeat; refer to the fire
control panel documentation for the procedure.
Each station address
MUST be unique. No
two stations may have
the same address.
For optimum performance
station address numbers
should be continuous.
