Glossary:
NO         : Relay normally open contact
COM       : Relay common contact
NC         : Relay normally closed contact
Open       : NO connection COM, NC disconnect COM
Close       : NO disconnect COM, NC connection COM
Momentary : Enter the Momentary command, the Rreceiver Relay is Open, delay of 0.5 seconds after, Relay is Close;
Toggle  : Enter the Toggle command, the Rreceiver Relay is Open, Enter the Toggle command again, Relay is Close;
Latched : Enter the Channel 1 Latched command, the receiver Channel 1 is Open, the Channel 2 is Close.
Enter the Channel 2 Latched command the receiver Channel 2 is Open, the Channel 1 is Close.
Enter the Channel 3 Latched command the receiver Channel 1 is Close, the Channel 2 is Close.
Delay : Enter the Delay command, the Rreceiver Relay is Open, delay of 0-9999 seconds(MODBUS command is 0-255 seconds )after, Relay is Close;
During the delay, Eter the Close command, immediately close the relay
Slave ID: A0-A5 is the slave ID, you can choose 64 different slave ID.
Under the MODBUS command mode,the slave ID must be correct
1 This version has 2 Command modes, MODBUS RTU Command and AT Command.  2 The default Command is the MODBUS RTU Command, compatible with older versions.
3 Switch to AT command by shorting the M0 pad.
4 The default baud rate is 9600BPS. You can also select the baud rate by shorting the M1 and M2 pads.
command Description, Please refer to “8 Channel Rail RS485 Relay commamd”
Typical applications:
1.When controlling a module, you can use the MODUBS RTU instruction or the AT instruction. In AT command mode, the dial switch (slave address) is invalid and can only control one module at a time.
2.MODBUS command mode (HEX), you can control a variety of ways: Serial Hyper Terminal Control (need to manually add the CRC), Modbus Poll software control (software automatically add the CRC), PLC or MCU process control
