POWER ON/OFF CONTROL
EXTERNAL POWER SWITCH
This switch is originally an “ON” only power switch. It can be programmed
into a power “ON/OFF” switch through software command. To program this switch,
the programmer needs to issue the following mentioned commands in the 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> in
hexadecimal format. (default status)
•
Change to power on/off switch -
- the command string is <1B> <19> <00> in
hexadecimal format.
SOFTWARE SWITCH OFF
An easy method for software control to turn the system off is the software off
switch. Usually the position LP of the 6 position key switch (or any other key or key
combination or any other position of the 6 position key switch as may be preferred) is
selected for this purpose.
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.
The programmer has to program the answer back code of position LP of the
programmable keyboard to some command to close the application program (such as
“Alt+F4”). At the end of the closing operation, the application program should issue
the following mentioned software switch off command string to COM1 under the
protocol: 9600 bps, parity none, 8 data bits, 1 stop bit. Or, as an alternative, the
programmer may program the answer back code of position LP to contain:
The closing command of the application program;
A certain period of hold on time to allow a safe closing;
The command to call for a program which will send the
software switch off command string to COM1 as described.
