When all the controllers are connected via TCP/IP, then the RS485 network becomes local (from Reader 1 to the Controller then
to the Reader 2).
Connect the readers directly to the Rs485 terminals in each controller.
If the distance Reader-Controller is high (50meters) and if the communication with the reader can not be established, then
terminate the RS485 network by closing the jumper in the EWS Controller or as described in chapter 5.1.
5.2 CONNECTING BIOMETRIC READERS WHEN ALL THE CONTROLLERS HAVE TCP/IP COMMUNICATION
5.3 RS485 TUNING
- Terminate both ends of the line with 120 Ohm resistor. If end of line is EWS, use built in resistor (120 ohm) by closing
the jumper.
- If the communicaon is not established and stable, use the external resistors provided in the hardware kit.
When using CAT 5 compable cable, in most of the cases, terminaon made with 50 Ohm external resistor or combinaon
of 50 Ohm external and terminaon resistor from the EWS (120 Ohm) should be the soluon.

NOTE: This is recommended configuration when you have multiple biometric readers in the same network. In this
configuration, NO TERMINATION resistors are required.
When all the controllers have TCP/IP communication the biometric readers are easily wired. When the controllers have RS485
communication, it is difficult to maintain the daisy chain of the RS485 network. Wiring the biometric readers in that formation
is a challenge. See the schematic diagram bellow.
