PRT-RDE2-PCB Protege Ethernet 2 Reader Expander Installation Manual | June 2017
2.11 RS-485 Biasing Settings
The Protege Reader Expander has biasing settings for the module network. Biasing can be configured for either
high or low (L indicates a low bias and H indicates high bias configuration). Both jumpers MUST be set to the
same bias type.
i

Biasing shall only be set to LOW on ONE point on any single segment of the RS-485 network. All
other devices on the same segment shall be set to the middle position which is no biasing.

By default, the PRT-CTRL System Controller has the jumpers for the biasing set to low and the
EOL jumper on. This is also the same default configuration for the slave communication port on
the PRT-RDI2 Protege Intelligent Reader Expander.
