Jumper block : Use the jumper block J25 to set the termination resistor on/off for the
MODBUS communication on the connector J1. For the first and last sensor adapter in
a series, their termination resistors must e set to ON. If not, communication between
sensor adapters is not possible.
2.11 LAN Signal Converter Kit (option)
The LAN Signal Converter allows the use of existing antenna cable RW-9600/6895/
4873 for TR-UP radar.
If the LAN Signal Converter is not attached in the antenna and power supply units, the
LAN Signal Converter Kit (optional supply) is required.

2.11.1 Application overview
The LAN Signal Converter has two applications.
Application 1: Use with existing antenna cable (retrofit)
Method 1: Using existing antenna cable
Use with existing antenna cable (RW-9600) in case of retrofit. The maximum length of
the antenna cable is 100 m for RW-9600, 50 m for RW-6895/4873.
The white, red, and green wires are not used. Attach a single crimp-on lug (FV5.5-
S4(LF), yellow) locally to the wires. (These wires will be connected together with the
shield of the power line, in the next section.)
