TTL Setup from Software
The 15 way TTL interface on the rear of the unit can be used to trigger from 1 to 7
channels independently and simultaneously.
To choose which channels you wish to control remotely, you will need to ensure that
the relevant pins on the 15 pin connector are connected to a suitable signal
generator and to the 15 way TTL interface at the rear of the niji. A BNC breakout cable
is available from Bluebox Optics.
TTL settings can be found in the “Configuration” tab on the niji software. There are two
ways to activate TTL mode. With the physical connections completed, either check
the “TTL Light Control” in the niji software (Figure 10), or send a serial command (page
27).
Active High or Active Low
TTL triggering can be configured in “Active High” or “Active Low” mode (see Table 2
below). “Active High” mode turns the specified channels “on” when a 5V logic level
is applied to a channel pin (Table 3) and “off” when a 0V logic level is applied. An
“Active Low” configuration turns the specified channels “on” when 0V is applied and
“off” when 5V is applied. The level of emission of each channel is set either through
the niji software or through serial commands.
Those channels that are not connected to the TTL interface will remain in their “on” or
“off” state independent of the emission status of any TTL controlled channels.
Example: Setting the blue channel to deliver 50% max emission when TTL is at 5V using
the software interface.
1.
Connect pins 6,7,8,10 to the ground pin of your TTL generator
2.
Connect pin 12 to the 0-5VDC output of your TTL generator
3.
Set the emission level of the blue channel to 50% using the software interface
4.
Activate the TTL Light Control by ticking the box on the software (Figure 8).
5.
Select Active High Input from the drop down menu (Figure 8).
6.
Select “100k Pull Up Enabled” (Figure 8).
When the TTL output is at 5V, the blue channel will emit 50% of maximum output power,
and 0% when the TTL is at 0V. To increase or decrease the level of output emission of
the channel, simply adjust the output whilst in TTL mode, and the channel output will
change to the new setting in the next on/off cycle.
In this example, those channels that are not connected to the TTL interface will remain
in their current “on” or “off” state independent of the TTL and emission status of the
blue channel.
