Z21
®_
Booster
The Z21
®
-Boosters is connected to the black Z21
®
by inserting the enclosed CAN-Bus cable in the “CAN“
socket. Which of the two CAN sockets are used is unimportant. Not only does the CAN-Bus transmit the
track signal that is to be boosted, it also provides for a comfortable configuration and firmware update of
the Z21
®
-Boosters via the Z21
®
maintenance tool. The received RailCom
®
data (RailCom
®
channel 2) are
also transmitted from the booster to the Z21
®
via CAN by means of a ZCAN20 protocol. This makes it pos-
sible to read out a vehicle decoder using the POM read command not only at the main track of the control
centre, but also in the booster section (Z21
®
FW V1.30 and higher is recommended). The track voltage
and the RailCom
®
settings can also be automatically taken over by the control centre (Auto-Settings).
Please also refer to Chapter: Configuration and Firmware Update via CAN and Z21
®
Maintenance Tool.
CAUTION:
The Z21
®
CAN-Bus can be set up with a linear and star-shaped combination. There-
fore, please never connect the Z21
®
-Boosters behind a 10808 occupied detector. Two examples
of a valid CAN-Bus cabling:
Connecting the Boosters
The Z21
®
-Boosters can be connected in one of three ways:
▪
CAN
▪
B-Bus
▪
CDE port
Please always keep to the selected connection form when connecting additional boosters.
