Your RF5xx Transmitter displays message ‘ErrOr 400’ on the LCD screen, similar to that shown here. This code is only seen on RF5xx Transmitters with Firmware Version 2.4.2 or lower.
This ‘ErrOr 400‘ indicates a user repairable fault with the Transmitter, in this instance there is an invalid programmed task on the device (flash read error).
To resolve this issue you will need to re-task the device. Unfortunately, if your Transmitter hasn’t sent any data since going into the error state, then that data will be lost when the unit is re-tasked.
To re-task a Transmitter, simply log on to the Gateway, locate the relevant Transmitter on the Homepage and click on the Summary Graph. Once on the ‘Summary’ page, click the ‘Task’ icon. You should double-check the settings for the task, before clicking on ‘Program Task’ (or ‘Program’).
Please allow up to half an hour for the Task to be successfully sent to the Transmitter, assuming a 15 minute radio rate. If required, you can speed the process up by ‘provoking’ the Transmitter using an RF525 Transmitter Activator.
If the ‘ErrOr 400’ message persists, even after re-tasking the Transmitter, then you should look to have it serviced.
Please click here for a copy of the Service Form which you will need to complete and include with any Transmitter(s) that you wish to return to the Service Department of Comark Instruments.
