NexLog Recorder User Manual v2.2.0
Appendix B: Optional General Purpose
Input/Output (GPIO) Boards
Note:
The optional GPIO board feature requires an add-on license key from Eventide.
The following uses can be made of a GPIO board:
The start and stop of recording on a channel can be triggered by a GPIO
board input signal. (For more information, see 4.4.1 Boards and Channels.)
The logic of GPIO-triggered recording can be customized using the custom
script feature.
A recorder alert can trigger a GPIO output signal. Alerts of severity 3 or 4
(Error or Severe) will by default trigger a signal on the first output pair of the
board. Further customization is possible via a custom integration script
available from Eventide.
Eventide supports the following optional GPIO board for use with recorders:
National Instruments PCI-6503 Board (24-Channel)
Important!
The National Instruments specifications for these GPIO boards describe the
maximum ratings for their input or output signals. Connections that exceed
these maximum ratings can damage the board and the recorder. Neither
Eventide nor National Instruments are liable for any damages resulting from
signal connections that exceed these maximum ratings.
National Instruments PCI-6503 Board (24-Channel)
This board provides a 24-bit parallel, digital I/O interface with:
24 static digital I/O lines (non-isolated 5 V TTL/CMOS) in 8-bit ports, 2.4
mA
50-pin male I/O connector (for ribbon cable with IDC-type connector)
No switches or jumpers
12 Channels are used for Inputs, and 12 for outputs
Note:
1. The I/O ports are not optically isolated.
Eventide has adopted static port assignments on the PCI-6503. See
GPIO Board Pin Assignments (NI PCI-6503)
