You can send a signal using the old fashioned LPT port using an RS232 cable (this requires a physical LPT card.) to your third-party device:
▪Select the option Send signal to LPT port to activate the signaling.
▪Enter the decimal LPT-port-address to which you connected your signaling cable (convert a hexidecimal value first).
| TIP: | Read Identify LPT-port Address for details. |
▪Select the pins that should be set 'High' to create the required signal for your third-party device.
This allows you to send any number between 2 and 256 as a binary code.
▪If you want to activate the specified signal for the next recording, activate the options Send trigger on record start and Send trigger on record end.
▪Confirm your settings with OK.
Note: To activate the specified trigger for your current recording, the Send trigger on record start option must also be selected.
The Send trigger on record end option only applies to UDP and Keyboard triggers.
When using the Mangold Vision Recorder software to send signals, these signals are send per stimulus, not just per recording session.
It is possible to combine several trigger types.
To test the signal without starting an actual recording, click on 'Test Start and Test Stop.
The biggest challenge for this communication method often is identifying the correct ID that can be used for communication.
▪Use a tool like the Parallel Port Tester of Doug Brown to identify the correct LPT port address.
▪Select one of the available ports in the bottom right corner of of that tool:
▪Click on one or more pins to send a signal.
If a signal is received by your system, you have the correct port.
▪If no signal is received, select another port and try again.
▪If you managed to send a signal to your device, note down the value inside the brackets.
▪Use a hexadecimal to decimal converter to convert the port ID to a decimal number:
▪Enter the decimal value as the LTP address in the Mangold VideoSyncPro Studio signaling settings.
