Cabling

1. Continuous Mode

Requirements

Submode 1:

• IMG-7W2-TO-1BNC required

• Video input BNC of IMG-7W2-TO-1BNC cable should be connected to VIDEO OUT

BNC connector of camera

• Camera must be configured in interlaced mode

Submode 2:

• IMG-7W2-TO-1BNC and PLS-TTL-CABLE required

• Video input BNC of IMG-7W2-TO-1BNC cable should be connected to VIDEO OUT

BNC connector of camera

• Camera must be configured in interlaced mode

Cabling
Requirements

• The following connections should be made between the DB-37 connector of the

PLS-TTL-CABLE and the 25-pin sub/D connector of the camera:

PLS-TTL-CABLE PHILIPS FTM12
(DB-37 connector) (25-pin sub/D connector)
Pin name Pin no. Pin name Pin no.

TTL_HSYNC 26 ← HDB 22
TTL_EXPOSURE1 9 → TRIGR 18
TTL_VSYNC 11 ← VDB 23

• Note here that the trigger input of the camera is tied to the exposure output of the

Pulsar, though the exposure output itself is not used; this precaution prevents the
trigger input from picking up stray signals that might lead to unwanted triggering of
the camera

Submode 3:

• IMG-7W2-TO-1BNC and PLS-TTL-CABLE required

• Video input BNC of IMG-7W2-TO-1BNC cable should be connected to VIDEO OUT

BNC connector of camera

• Camera must be configured in non-interlaced mode

• The following connections should be made between the DB-37 connector of the

PLS-TTL-CABLE and the 25-pin sub/D connector of the camera:

PLS-TTL-CABLE PHILIPS FTM12
(DB-37 connector) (25-pin sub/D connector)
Pin name Pin no. Pin name Pin no.

TTL_HSYNC 26 ← HDB 22
TTL_EXPOSURE1 9 → TRIGR 18
TTL_VSYNC 11 ← FVDB 20

• Note here that the trigger input of the camera is tied to the exposure output of the

Pulsar, though the exposure output itself is not used; this precaution prevents the
trigger input from picking up stray signals that might lead to unwanted triggering of
the camera

2. Trigger Mode

• IMG-7W2-TO-5BNC cable and PLS-TTL-CABLE required

• Video input BNC of IMG-7W2-TO-5BNC cable should be connected to VIDEO OUT

BNC connector of camera

• Camera must be configured in non-interlaced mode

• The connections between the DB-37 connector of the PLS-TTL-CABLE and the 25-pin

sub/D connector of the camera are the same as those in Continuous mode: Submode 3.
The connection between the trigger input of the camera and the exposure output of the
Pulsar is now used to send asynchronous reset and exposure signals to the cameraTTL
external trigger source should be connected to the TTL Trigger Input of the IMG-7W2­TO-5BNC cable

continued

• Video input BNC of IMG-7W2-TO-5BNC cable should be connected to VIDEO OUT

BNC connector of camera

• Camera must be configured in non-interlaced mode

• The connections between the DB-37 connector of the PLS-TTL-CABLE and the 25-pin

sub/D connector of the camera are the same as those in Continuous mode: Submode 3.
The connection between the trigger input of the camera and the exposure output of the
Pulsar is now used to send asynchronous reset and exposure signals to the camera

• TTL external trigger source should be connected to the TTL Trigger Input of the IMG-

7W2-TO-5BNC cable

4. Continuous Mode:

• A table of integration time settings for the Continuous mode can be found in appendix 2 of

the User Manual for the FTM12 camera

5. Trigger Mode:

• Once it has received the external signal to trigger, the Pulsar sends a TTL exposure signal

to the camera. The camera awaits the rising edge of the signal, at which point it initiates
exposure. The exposure time is set on the camera by using the camera control software

• A table of integration time settings (for both ranges 1 and 2) for the Trigger mode can be

found in appendix 3 of the User Manual for the FTM12 camera

• An exposure pulse going high before the integration period has ended will result in a

charge reset; the integration time counter resets and starts again from zero

• Minimum duration of an exposure pulse must be 3.2µs

Special
Considerations

3. Control Mode:

• Once it has received the external signal to trigger, the Pulsar sends a TTL exposure signal

to the camera. The camera awaits the rising edge of the signal, at which point it initiates
exposure. The exposure time is set by the Pulsar; the camera will expose for as long as the
exposure signal is high

• When the exposure pulse goes down, frameshift will start. If there is an exposure pulse

before the complete storage part is read out, the rest of the image will be lost and the
sequence starts again. Using this feature it is possible to get a higher frame rate if part of
the image is not needed

Considerations

• Exposure time can be modified using Matrox Intellicam. Consult the Matrox Intellicam

User Guide for more information

• Default exposure time is 10ms
