Receiving and Sending Serial Data (RS-485)
The encoder receives and sends serial data (duplex) as shown in the illustration below.
Required Settings for RS-485
Perform the following settings to receive and send serial data.
• Enter the desired size of the packet to be sent in the "WAITING DATA SIZE TO SEND PACKET (1 - 1024 byte)"
input box on the RS-485 DATA PORT page.
The packet will be sent when its size reaches the entered size.
• Enter the desired waiting time to send in the "WAITING TIMER TO SEND PACKET (10 - 1000 ms)" input box on the
RS-485 DATA PORT. The packet will be sent when the entered time has passed.
• Enter the desired port number to be used for receiving UDP packets from the network in the "RECEIVING PORT
No." input box on the RS-485 DATA PORT page.
When the receiving serial data size reaches the entered size in the "WAITING DATA SIZE TO SEND PACKET" input
box on the RS-485 DATA PORT page or when it has reached a waiting time for receiving data longer than the entered
time in the "WAITING TIMER TO SEND PACKET" input box on the RS-485 DATA PORT page, the encoder will attach
MAC, IP and UDP to the packet and send it to the network.
The received packet from the network will be converted to serial data by deleting MAC, IP and UDP, and then it will be
sent to an RS-485 device from the RS-485 data port of the encoder.

page or when it has past a longer waiting time for 
receiving data than the entered time in the
