modes will be discussed in more detail in section 9.0. Enabling and
disabling a channel can also happen on the fly in all modes except Burst
Mode. In Burst mode, enabling/disabling the channels is not available and
Channel 1 and 2 are enabled, Channel 3 and 4 are disabled automatically.
When the mode is switched from Burst mode, the enable/disable settings
will return to where they were previous to Burst mode. The trigger can be
set to internal or external in pulse generation and pulse count modes.
Note that the unit will “lock up” until it has finished it’s pulse count in
external mode so the external triggering device must give it AT LEAST as
many pulses as is entered. If this does not occur, the device can be
“released” by switching modes. The sync can also be run off any channel
except under Burst Mode. This is especially useful in Divide By N mode
and pulse count mode. Not that in Burst mode, the sync is a packet period
limited by at most 95% duty cycle regardless of this setting.
OUTPUT MENU2
OUTPUT MENU2 is where the unit can change the trigger, adjust the
contrast settings of the unit, and set the logic applied to the output of all
Channels. The operating modes will be discussed in more detail in section
9.0. The trigger can be set to internal or external in pulse generation and
pulse count modes. Note that the unit will “lock up” until it has finished it’s
pulse count in external mode so the external triggering device must give it
AT LEAST as many pulses as is entered. If this does not occur, the device
can be “released” by switching modes. The sync can also be run off any
channel when the unit is not in Burst mode (Note that in Burst mode, the
sync is a packet period limited by at most 95% duty cycle regardless of
this setting and outputs on Channel2 as well as the SYNC output.
The contrast setting can also be changed in this menu. If the contrast is
adjusted by using the encoder knob or using the x10 button, a ‘?’ will
appear at the end of the setting. This means that while the unit is powered
this is the setting that the unit will retain but when powered down and
powered up again the unit will revert to the last saved contrast. By
depressing the ENTER button the contrast will be saved in non-volatile
memory and the unit will come up under this contrast setting. The contrast
is has numerous settings, and a coarse and a fine adjust. The letter is a
course adjustment and the number is the fine adjust. The course adjust is
manipulated with the x10 button and the fine adjust is set by the encoder
knob. Logic allows the user to logically AND or OR outputs OUT1 and
OUT2 with each other and OUT3 and OUT4 with each other. LOGIC1 will
output on the OUT1 channel (note: the invert function will invert the
channel AFTER the logic has been applied – this is shown in the LOGIC
AND POLARITY FUNCTIONAL DIAGRAM below). LOGIC2 will output on
the OUT2 channel, LOGIC3 will output on the OUT3 channel, and
LOGIC4 will output on the OUT4 channel.
