FAQS about this product

What is the best way to power on my system/network for the first time?

When powering on your system for the first time you must follow the below order of start up:

1. Coordinator/SALH
2. Repeaters (if any)
3. IRT Nodes

The coordinator/SALH and the repeaters share the same MAC address so they both could act as coordinators*. If the repeater is powered on BEFORE the coordinator/SALH, that particular repeater can take the “lead” and act as the coordinator.

* This only applies to the older version, 2B, radio chips.

How many IRT's can I have on one network?

The Dynamax IRT Coordinator Module handles up to (10) wireless IRT sensors directly, or add routers to expand the network and include up to (27) IRT sensors.

The Dynamax SALH System handles up to (10) wireless IRT sensors directly, or add routers to expand the network and include up to (25) IRT sensors.

How do I check the battery voltage on an IRT?

To check the battery voltage you will need a voltmeter. Place the negative lead (black) on the ground terminal, located at the top of the enclosure near the LED lights, and the positive lead (red) on the terminal where the red wires meet at the bottom of the enclosure. The battery needs to to read at least 5 V to properly run the IRT unit.

Some IRT's are not being detected by my coordinator/SALH.

This is the most common problem customers encounter and is usually one of two issues. One, the IRT has a low battery (see above FAQ for how to check the batery level). Two, the IRT does not have the same network settings as the coordinator/SALH (Pan ID and Scan Channel). Please refer to the manual on how to check/change network settings.

My computer does not have XCTU, where can I download this?

XCTU

What is the size of the area my IRT is reading?

The IRT sensor has a very narrow 20 deg field of view. It has a 1:3 ratio target.

For example; at a 20 degrees FOV one would have a complete coverage of 95%. So, for a 1 meter wide target, the customer would have to place his or her IRT 3 meters above the item or surface being measured.
