Description
With the VS board, first the input PC frequency and full line number are measured. Next, if there are preset
models which have three matching measuring data, it is determined that these models are connected and they
are set into the autolock state.
In the autolock state, 01 AUTO is displayed by the STS command.
If there exists no preset model data corresponding to the measuring data, all models are autolocked to Mode 99.
(Refer to “MODE 99”.)
Take note that there are DOS/V personal computers which have 640 effective dot number and 480 effective line
number but a different full line number (526 or 524) from the standard VGA 525. In this case, their models are
autolocked to Mode 99.
As the frequency is close to the VGA, when the VS board is forcible locked to the VGA by M01 and data is output,
the image frame, etc. will be optimum. In this way, the M command is used when using the preset data as
substitute data.
13. USING METHODS OF HFQ, VFQ, VLN
There is a need to autolock unpreset models without using the Mode 99 accoridng to the state in which the VS
board is used.
The procedure is as follows.
1. Input a PC without the preset data.
2. Autolock to 99.
3. Check the frequency and full line number using the FRQ command.
4. Forcible lock using the M command to the model with a similar frequency.
5. Input the checked data using HFQ, VFQ, and VLN.
6. Execute M00 and check that it has been auto locked.
Unpreset models can also be autolocked using the above procedure. To set back the original state, use the F
command.
