J2 Pin DB-15 (Female) Description
1 Single Strobe
TTL output signal used to pulse a strobe that is high at the start of each
integration period.
2 Continuous Strobe
TTL output signal used to pulse a strobe that is divided down from Master
Clock signal.
3V
CC
The positive supply voltage +5VDC.
4
External Hardware
Trigger
TTL trigger signal (rising edge trigger input) used in the External Hardware
Trigger mode.
5
External Synchronization
Trigger
TTL signal used to define the integration time (time between rising edges)
when using the External Synchronization Trigger mode.
6 Channel 7 The analog input for spectrometer slave channel 7.
7 Channel 6 The analog input for spectrometer slave channel 6.
8
D3 or External Software
Trigger
Active high TTL input signal used to trigger the acquisition system in the
External Software Trigger mode. The input from J1-8 is passed unbuffered
to this line.
9 Channel 1 The analog input for spectrometer slave channel 1.
10 GND Ground (supply voltage return) or case ground.
11 Channel 4 The analog input for spectrometer slave channel 4.
12 Channel 5 The analog input for spectrometer slave channel 5.
13 S0 and S1
TTL inputs used to determine the triggering mode:
S1 S0 Mode
L X Normal or Continuous Scan
L X External Software Trigger
H L External Synchronization Trigger
H H External Hardware Trigger
X = does not matter
In the first 2 modes, S0 is also used to enable/disable light sources.
14 Channel 3 The analog input for spectrometer slave channel 3.
15 Channel 2 The analog input for spectrometer slave channel 2.
