family controllers do not have the connector using the programming key code PCO201KEY0. To
program the controller, use the new Smart Key (PCOS00AKY0) available from September 2005. Otherwise
use WinLoad ver. 3.35 and higher:

Contact REHAU for the availability of the latter.
Procedure for setting the address of the controller and terminal
Setting the address of the controller
The pCO
3
controller does NOT have dipswitches for setting the pLAN address. The address must be set by
software, as for the pCO
1/XS
.
The procedure is as follows:
switch the pCO
1.
3
off;
prepare a standard REHAU terminal with the address set to 0 (not necessary if the pCO
2.
3
Built-In terminal is
used). For this operation, see the following paragraph;
connect the terminal to the pCO
3.
3
;
disconnect any other devices connected in the pLAN from the pCO
4.
3
(terminal J11);
switch the pCO
5.
3
on, pressing the UP + ALARM buttons at the same time. This combination of buttons is the
same on the built in terminal. Alternatively, on the PCOT terminals, use the combination of the
menu
and
buttons.
after a few seconds, the following screen will be displayed:
6.
PLAN ADDRESS: 0
UP: INCREASE
DOWN: DECREASE
ENTER: SAVE & EXIT
to modify the address simply use the UP and DOWN buttons and then press ENTER to confirm.
7.
now set the pLAN address of the terminal and configure the pLAN network.
8.
Setting the address of the terminal
pCOI/pCOT terminal
The address of the terminal is set using the DIPSWITCHES on the rear of the terminal.
pGD0/1/2/3 terminal
The default value of the address is 32.
The address of the terminal can only be set after having connected the power supply via the telephone
connector.
To enter configuration mode, press the
↓↑
џ
buttons at the same time (even when the terminal is already on), in all
the versions, for at least 5 seconds; the following screen will be displayed, with the cursor flashing in the top left corner:
Display address
setting.........:nn
I/O Board address:xx
to modify the address of the terminal (display address setting) press the
џ
button once: the cursor will move to the address field (nn).
