Network Termination

When building a Lonworks system the network must be properly terminated by positioning
the BTK-8102 Lonworks terminator in the DX8200A master reader and the BTK-8100
Lonworks bus return in the last DX8200A slave reader.
The BTK-8100 bus return provides a connector to be inserted in the Lonworks 17-pin female
connector of the last slave reader in the network; while the BTK-8102 Lonworks terminator
provides a different connector to be inserted in the Lonworks 17-pin male connector of the
master reader:

Two cables are also provided as accessories to terminate and power the network: CAB-8605
and CAB-8305.
CAB-8605 is a power and Lonworks termination cable to be used for connecting the
DX8200A master to an external power unit within the network; while CAB-8305 is a power
and bus return cable to be used for connecting the last DX8200A slave to an external power
unit. These two cables must only be used for VDC models.
