iRn IR Driver Interface
The iR5/iR10 is a specialized interface for up to five or ten infrared sensor beams. This module has built-in power and logical connections to drive external IR sensors. It sends TTL events whenever the subject crosses the beam, without the need for any external signal processing. Manual trigger buttons for each IR port simplify testing and debugging Status lights for each IR beam monitor subject movement during sessions. For information on software control of the iRn, see the Synapse Manual.
Manifolds
The iRn connects to a manifold via a DB25 cable.
iRSD38
The iRSD38 is an IR driver and sensor that connects to the iR5m-RJ / iR10m-RJ
manifolds to form a beam break. The drivers have a red band around them and
the sensors have a blue band. The modules have two mounting holes for flathead
4 screws. The standard cable length is 42″.
Output Power
The IR LED output power is adjustable through Synapse software configuration (1-8). This adjusts an in-line resistor value from 4 kOhm to 500 Ohm. Power output depends on this power setting and the voltage drop of the LED. The table below shows the supply current for a typical IR LED with a 1.4 V voltage drop.
Sensor Input
The sensor power output has a 10-ohm resistor in line. The output voltage changes with the current draw is as follows:
Receiver Pinout
When the Sensor output is pulled low, it triggers the event.
