- Analog output associated with any MP module (DA100C, ECG100C, etc.) that is sending data to an MP System on analog input channels 1-16.
- Analog output coming from the MP system via one of its D/A converters on analog output channel 0 or 1.
- Threshold View—shows the Threshold (Trigger) Level
- Trigger View—shows the Trigger Output as sent to the external equipment.
- Signal View—shows the analog input signal as sent to the DTU100.
Connect a TTL line with BNC female connector between the DTU100 and your trigger device.
The DTU100 incorporates an optional Automatic Level control circuit. The Automatic Level control circuit will expand or compress the analog input signal to fit inside of a ±5 V range.
- If the analog input signal is clearly defined, run the DTU100 in Normal mode.
- If the analog input signal has a widely varying baseline or significant change in amplitude from one desired trigger point to the next, consider operating the DTU100 in Auto Level mode, or try to improve signal definition.
The Trigger LED (green) will light up whenever the Trigger Out signal goes high.
If analog data is above the threshold setting, the DTU100 output can be set to either high (+5 V) or low (0.0 V). When analog data drops below the threshold value, the output will be the opposite level.
Select a trigger level (or threshold) that will fire when analog data reaches that threshold.
High-level output transducers and adapters connect to the AMI100D/HLT100C via standard 6 pin RJ11 type connectors. Transducers and adapters that presently require the AMI100D/HLT100C module are:
- TSD109C3/J1 Tri-axial Accelerometers
- TSD111A Heel/Toe Strike Transducer
- TSD115 Variable Assessment Transducer
- TSD150A/B Active Electrodes
- INISO Adapter – Input Signal Isolator
- OUTISO Adapter – Output Signal Isolator
- DTU100 Digital Trigger Unit (MRI Synchronization)
