Programming the MCU
The MCU programs is by way of the follwing method:
Host communication interface: RS-232 •
Support buad rate: 57600/ 8N1 •
Communication protocol: ANSI terminal. •
The MCU commands:

Example
1. Set the delay time for power-on delay:
>SET POWERON_DELAY 4 (Set powe-on delay to 4
seconds)
>OK (System response)
>GET POWERON_DRLAY (Get the power-on delay time)
in seconds
>POWERON_DELAY=4 (System response)
The above command sets POWERON_DELAY =10
The above command sets SHUTDOWN_DELAY=10
2. Read the current power state
GET POWER_STATE (Get power state command)
POWER_STATE=STARTUP (System response)
The above command reads the current power state.
3. Read/write digital output state
>SET DIGITAL_OUT 3 (set digital_out bit 0=1 and digital_
out bit 1=1)
>OK
