6) This shows the time to finish processing serial port when there is no response after command
from COM port.
7) When the end code is CE or CR+LF, CR and CR+LF in the command are ignored.
8) In case of that the end code is none, it processes the data max 1460 byte per a IP packet.

Note1) You can select MODBUS TCP (RTU, ASCII) added to TCP for transport layer
protocol of Ethernet. (Firmware V1.03 or more)
2) “502” is recommended when connecting MODBUS TCP. When MODBUS TCP is set
to main COM port, set the other port to another port.
3) The time from when it comes no connection after establish TCP connection to cut
TCP connection when connect by MODBUS TCP. If set to “0”, KS1 Signal converter
keeps TCP connection until when MODBUS TCP client cut correctly. However,
without transmission for 2 hours, it cut TCP connection.
4) When it doesn’t cut correctly during TCP connection, KS1 Signal converter keeps
the TCP connection until the setting time. Considering read out cycle of using
application, set the timeout.
5) With serial communication conditions, when the end code is set to CR or CR+LF, it
cut the connection by receiving data 4k byte ore more.
When the end code is none, it proceeds by 1460 byte (max of one IP packet) or it
doesn’t cut TCP connection without proceeding to store the several packets.
