GO-5000M-PGE / GO-5000C-PGE- 17 -6.2.6 Line FormatIndicates the format of the line item selected in Line Selector.(No Connect, TTL, LVDS, Opt Coupled or Internal Signal)Note: In the GO-5000-PGE, TTL and LVDS interface are not equipped.6.2.7 Action ControlAction control settings allow the use of unicast or broadcast Action Commands as defined in theGigE Vision 2.0 specification. ACTION_CMD messages received via the GVCP port can control thecamera’s internal action signals provided the camera’s action control settings match the settings ofthe message received. This function is useful for triggering an action in multiple cameras at roughlythe same time. There are two action control inputs on the GO-5000-PGE and they are connected tofour triggers, counter reset, counter, and timer.When action control is used, the trigger input source should be set to Action 1 or Action 2 inadvance.6.2.7.1 ActionDeviceKeySets the device key value for the camera in a 32-bit register. This value must match the device_keyvalue of the ACTION_CMD message in order for the message to be acted upon. .6.2.7.2 ActionSelectorSelects Action 1 or Action 2 for setting the action control values.6.2.7.3 ActionGroupKeySets the group key value for the selected action signal in a 32-bit register. This value must matchthe group_key value of the ACTION_CMD message in order for the message to be acted upon.6.2.7.4 ActionGroupMaskSets the mask value for the selected action signal in a 32-bit register. This value is compared againstthe group mask value of the ACTION_CMD message to determine if the message should be ignored oracted upon. A logical AND operation is used and must produce a non-zero result or else the messageis ignored..6.2.8 GPIOThis is a general interface for input and output and controls input and output for trigger signals orvalid signals and pulse generator. By using this interface, you can control an external light source,make a delayed function to input a trigger signal or make a precise exposure control with PWCtrigger.
