Command mode selection :( figure above) M0 disconnect is MODBUS command mode. M0 Connect is AT command mode.
Output level selection : ( figure above) M1 disconnect is Low level output. M1 Connect is Hight level output
Slave ID: Different ''Sliver ID'' can be set by command, the maximum number is 247
Under the MODBUS command mode,the slave ID must be correct
command Description, Please refer to '' TL19A08 8-channel TTL output module commamd''

Typical applications:
1 AT command mode (M0 Connect), in this mode can be through the serial HyperTerminal (serial assistant) enter a simple AT command control relay. AT command mode time up to 9999 seconds
2 MODBUS command mode (M0 disconnect), 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
It can control 1-8 channels 5V/6V/9V/12V/24V Relay Module
With RS485 interface and RS232 (TTL) interface
