6. TRIGGER SIGNAL BOARD
The oCam-1CGN-U-T can be used with any signal source as long as it meets the input signal
specification. It is recommended to use the mTrigger, however, which is a trigger signal board
supplied by the WITHROBOT Inc. for full compatibility and verified operation.
The mTrigger signal board supports the following 4 signal modes which are all user
programmable to set the detailed signal parameters.
