Connections

Three electrical connections and one optical connection are required to operate the MyoCam-S: AC to the
Power Supply, Power Supply to the camera, camera to the computer and and camera to the optical image
source.   There are also optional Auxiliary input and outputs and Synchronization connections.

Power

The AC power entry and associated fuse holder are accessible on the
back panel of the MyoCam-S power supply.  It is a NEMA standard
power entry that can be used with any compatible power cord. 

Note - The Power Supply will automatically adjust to any main voltage
between 100 and 240 volts AC.

Power entry

Camera Connections

The following connections are made to the camera:
1. The "CONTROLLER" plug connects to the the Power Supply using the

supplied DVI-I dual-link cable.

2. The "USB2" plug connects to the computer using a standard USB 2.0

cable. 

3. A standard c-mount microscope adapter connects the camera to the

microscope.

Camera connections

Auxiliary Connections

The following optional connections are available on the front of the
MyoCam-S Power Supply:
CLK OUT

50% duty cycle programmable TTL clock output for
providing a common time base to other devices.
The specific frequency of this clock is set in the 

Trigger/Outputs Properties

 page of the 

Camera

Properties

 dialog.

Auxillary connections

REP OUT

1µs positive-going TTL pulse that indicates start of each image frame.

PRE OUT

Programmable duration, positive-going TTL pulse that occurs a
programmable time after the the start of image acquisition.  The width and
delay are set in the Output Sync Pulse section of the 

Image Format/Timing

Properties - Advanced

 tab of the 

Camera Properties

 dialog.

 TRIG IN

(FUTURE USE - CURRENTLY DISABLED) 
TTL Input that synchronizes start of image frame acquisition to the rising
edge of the input signal. The trigger input must be enabled in the Trigger
section of the 

Image Format/Timing Properties - Advanced

 tab of the

Camera Properties

 dialog.

Sync Connections

To synchronize multiple MyoCam-S cameras in a master/slave relationship,
you need to connect the Sync Out (located on the rear of the Power
Supply) for the "Master" camera to the Sync In  (located on the rear of the
Power Supply) for the slave camera.  In addition to making the physical
connections, you must enter the correct settings in the 

Trigger/Outputs
