Troubleshooting Offline Transmitter(s)

OVERVIEW:

The Tehama transceivers have 2-way communication in the form of an LED status light on the front of the device. This will change color based on the reception levels and lag time that it takes for the radio signal to reach the DCAP. If your Transceiver is stating it is offline, the first step would be to verify the transceiver is not in a sleep state or down state due to poor reception. Below is the basic reset guide for each type of transceiver and the steps to reset the connection to the DCAP. 

Tehama Reset Guide:

This guide is to help show you the difference between a soft reset and a hard reset, and when to use which. A hard reset is the best option when resetting transceivers, where a soft reset is mainly used for storing purposes.

Soft Reset/Sleep mode

Hold the power button (Small red Tehama logo on the front of the device), or magnet (Ceramic square magnet) to the Transceiver for 6 seconds. The LED will be lit up while you are doing this. At 6 seconds the LED will turn off and then on again. When this happens, release the button/magnet.

Sleep mode - LED flashes twice and turns off

Normal Mode - The LED will flash slowly until it connects to the DCAP. When this happens, it will stay solid for a few seconds before turning off.

Hard Reset

Hold the power button/magnet to the Transceiver for 12 seconds. At 6 seconds you will see the LED flash on and off, at 12 seconds the LED will turn off and stay off. When this happens, release the button/magnet. The Transceiver will then attempt to reconnect to the DCAP.

When to use a Soft Reset vs. Hard Reset

A soft reset allows you to put the Transceiver in and out of sleep mode. This is good for when you are storing Transceivers when not in use or when you first set up the Transceiver after connecting them to a meter.

A hard reset is used when the status light of a Transceiver becomes yellow or red. This forces the Transceiver to reset internally and usually resolves connectivity issues as well as latency issues. This is the preferred method to use when Tehama transceivers are not checking in as it will not accidently put the Transceiver back into sleep mode by mistake.

Tehama Transceivers not checking in after reset:

If the Transceiver is on but still is having issues connecting to the DCAP, it may need a little help. If the unit this Transceiver is attached to is far away from the DCAP, remove the Transceiver and walk it next to the DCAP. Do the steps above to force the Transceiver to connect (if you are near the DCAP there will be no signal interference and this should connect). After the light goes solid green, walk it back to the location it will be installed. This should make it so the Transceiver and the DCAP shake hands. This usually resolves any connection issues that may be occurring due to distance or for pit meters having the signal get above the ground initially.

If unable to resolve:

If after you have followed these steps and haven’t gotten equipment online, the next step is to set up a time with one of our technicians to troubleshoot over the phone. It is critical that the person talking with our team is on-location with the equipment during the call. We will not be able to troubleshoot further without direct access to the equipment.
