Chapter 2: Getting Started
2 – 13
ZVGTWEAK will start by reading and displaying the version information of the ZVG.
It will then begin displaying a Zektor logo on the vector monitor. Since the monitor
is not powered on, the only indication of anything being displayed is the status light
D4. This light should be lit, and may be a bit dimmer than the power indicator D3.
The status light D4 blinks each time a vector is being drawn, and so appears to be
dimmer than D3 which is always on.
Step 4: Powering on the Vector Monitor
Assuming all has gone well, turn on the Vector Monitor. You will possibly hear the
sound of vector chatter (depending upon you monitor), and upon power up you
should see the Zektor logo test screen.
The ZVGTWEAK Version 1.0 Command Set.
ZVGTWEAK allows one to “tweak” the internal timing values used by the ZVG while
drawing vectors. A frame of vectors will be continuously drawn. By pressing com
-
mand keys, the timing values can in incremented/decremented.
After the values are changed, the new values reside in RAM in the ZVG and are in
effect until power is cycled. On power up all timing values are read from an internal
EEPROM.
After changing the timing values, ZVG tweak allows you to write these values into
the internal EEPROM to allow them to remain in effect after power is cycled.
If one accidently writes bad values into the EEPROM, there is a Restore factory
default command which set the values to the generic values shipped with the ZVG.
These values are not automatically written back to EEPROM, the write to EEPROM
command must be issued separately if you wish to save the factory default values to
EEPROM.
Each monitor speed has its own internal EEPROM area, so changing values for a
15us G05 monitor will not effect the values of the WG6101 30us settings. ZVG
tweak only allows you to adjust the values of the current speed settings. The differ
-
ent speed settings are set by J3-SP1 and J3-SPD2. These jumpers must match the
settings of J4. (See Chapter on Monitor Settings.)
The program is menu driven, use the UP/DOWN arrows to select the desired param-
eter, then use the LEFT/RIGHT arrows to update the value.
