TP-5700/5800 series Technical Manual 5 - 3

application program to COM1 under the protocol: 9600 bps, parity none, 8 data bits, 1

stop bit.

• Change to power on only switch – the command string is <1B> <19> <01> or

alternatively <1B> <00> <00> <00> <00> <00> <00> <18> in hexadecimal format.

• Change to power on/off switch -- the command string is <1B> <19> <00> or

alternatively <1B> <00> <00> <00> <00> <00> <18> <00> in hexadecimal format.

(default status)

In case the power switch status has been changed from the default status, the

switch function will remain after power off. However, if the AC power has been

disconnected during the power off stage, such change will be discarded. Therefore, it is

advisable for the application program to reinstate the switch function every time the

system is rebooted or every time the program is executed to ensure the proper action of

the power switch. This function can also be achieved by use of the Posiflex Touch

Terminal Manager.

SOFTWARE SWITCH OFF

An easy method for software control to turn the system off is the software off

switch. The hexadecimal command string for software switch off function is :

<06> <16> <19> <1D> <n>.

In the above, the “n” indicates the time delay in seconds for actual power off

after the command string given to COM1. However, an alternative command string

<1B> <00> <00> <00> <00> <00> <00> <00> can be used instead to turn off the

system power immediately.

Some operating system or software may require complete termination of

application programs before system power off for the sake of system maintenance. In

that case the programmer has to program the command to close the application

programs (just like “Alt+F4” in Windows), and then at the end of the closing operation,

the application program should issue the above mentioned software switch off

command string to COM1 under the protocol: 9600 bps, parity none, 8 data bits, 1 stop

bit.
