Legacy biomet packages

Here we describe how to connect sensors and enter calibration information for the four legacy sensor packages from LI-COR. Although we show how to connect the Stevens HydraProbes, they must be connected and configured one after the other until each one has a unique address.

Biomet Package 1

Part number 7900-101

Biomet Package 1 supports sensors listed in Table C‑1.

Wiring table

Wiring assignments are given in Table C‑1 and Figure C‑1.

Table C‑1. Wiring for Biomet Package 1. If a sensor has wires that are not mentioned here, those wires are not used and can remain unconnected.

Connecting the optional CNF4

If you have two DAqMs, the CNF4 wires connect to the DAqM. The CNF4 is controlled by the DAqM's switched power supplies. The green and gray wires for the tachometer are not used.

Connecting the optional CNF4

For Sensor Package 4, you'll need to install two relays and wire leads, which are required to actuate the relays and provide the timer-controlled power to the CNF4. The CNF4 wires connect to the relays and DIN terminals. The green and gray wires for the tachometer are not used.
