Module codes of EMA-4/4 AND EMA-4/16 Devices and the Corresponding Digital I/O Channel Numbers

Digital I/O channel numbering rules:

  • The Digital I/O channel numbering system is based on module codes. In a synchronized multichannel AE diagnostic system formed from EMA-4/4 and/or EMA-4/16 devices, all Digital I/O channels have different channel number.

  • All EMA-4/16 devices have 8 Digital I/O channels. For any of these devices the starting Digital I/O channel number is: (Module_CodeEMA-4/16 – 1)*16 + 1.

  • All EMA-4/4 devices have 3 Digital I/O channels. For any of these devices the starting Digital I/O channel number is: (Module_CodeEMA-4/4 – 1)*4 + 1.
