Installation and commissioning.
GCLR-I 2000/GCLR-O 2000
DIP switch 6-12: BUS addresses
Up to 128 addresses can be set using DIP switches 6-12. Max. 2 addresses
are required for connection to the GCDU 200.
Address "0" = DIP switch 12 "OFF"
Address "1" = DIP switch 12 "ON"

Transponders
4.5.1 Transponders with keys
Standard transponders transmit their "electronic keys" automatically to the
reader as soon as they enter the LF scanned field.
In addition, there are transponders which have 2 additional keys.
These keys can be used to transmit the "electronic key" by wireless techno-
logy (HF) to the reader from a distance of up to 50 m.
The function of the keys must be activated via the configuration software
(see Chapter 5.2.2). Here it is possible to select which keys switch which
output or whether both outputs are to be switched when one of the keys is
activated.
4.5.2 Transponder battery monitoring
The transponders have a battery as their energy source.
If the battery voltage approaches a critical value, the red LED on the reader
housing or on the transponder with keys flashes as long as the transponder
is within the scanned field.
4.5.3 Multiple teaching of transponders
A transponder is touched to the reader only once and stored with its ID
number. If the transponder is touched to the reader a second time, this has
no effect and no further memory space is occupied. This guarantees that up
to 300 transponders can be taught.
4.5.4 Several transponders in the scanned field during teaching/deletion
If there are several transponders in the scanned field during teaching/
deletion processes, it is possible that only one (or none) will be taught or
deleted, since the transponders can override each other in learning mode.
4.5.5 Operation of several transponders in the scanned field
The system works with intelligent anti-collision functions in order to com-
municate with many transponders at the same time. If there are several
transponders within the scanned field during scanning, one valid
transponder is sufficient to trigger the switching processes. In networked
operation, all the transponders within the scanned field are reported via the
