1.5 RS485 BIASING AND TERMINATION
The ONICON D-100-P1 does not provide biasing voltage or termination to the RS485 network. A
120W termination resistor should be used when the display is installed at the end of the line.
1.6 NETWORK ADDRESSING
Before the D-100 can communicate on the P1 network, the appropriate device address must be
programmed into the display. The P1 network address for ONICON D-100 Flow Displays may
be set to any address from 1 to 99. This address is set at the display. Section 1.6.1 details the
procedure for changing this address.
1.6.1 Changing the Device Address
Every ONICON D-100 is individually programmed at the factory with application specific
data provided by the customer during the ordering process, and this may include network
addressing information. If the device address information was provided, the display
will be programmed with that number. If no address is provided, ONICON displays are
programmed with a default address of 017. The address may be changed at the D-100
using the procedure outlined in the table below.
