Cyrus PSU-XR

User Instructions

Firmware

From time to time there may be a requirement to check 

the firmware version installed in the PSU-XR. This may be 

necessary to ensure compatibility with connected Cyrus 

products or to assist with technical or service questions.

Checking the version from the PSU-XR

The PSU-XR firmware version is displayed as a code on 

the Standby/Status indicator when mains power is first 

connected. The version is read as follows -

•  Connect mains power.

After a short delay the Standby/Status LED will indicate 

the firmware version with a sequence of red flashes (the 

first digit) followed by a sequence of green flashes (the 

second digit). The absence of green flashes indicates the 

second digit is 0.
The sequence ends with the Standby/Status indicator 

lighting red continuously to indicate standby mode is 

now set.

For example -
1 x red flash followed by 2 x green flashes followed by 

continuous red (standby) indicates V1.2. 
2 x red flashes followed by continuous red (standby) 

indicates V2.0.

Checking the version from a connected Cyrus product

The PSU-XR firmware version may also be read directly 

from any connected Cyrus product which has a front panel 

display screen.
• 

Open the settings menu of the connected Cyrus 

product.

• 

Select the PSU-XR menu option.

Firmware and hardware version information will be 

displayed for the PSU-XR.

Updating the firmware

If an updated firmware version is available, this may add 

new features, further enhance compatibility with the Cyrus 

range or fix operational issues.
If new firmware is available from the ‘Support’ pages of the 

Cyrus website www.cyrusaudio.com, this will be packaged 

with other documents including -

•  Firmware version change log.
• 

Latest firmware update procedure.

• 

Revised handbook (if required).

NOTE: Updates to the PSU-XR firmware may also require 

a firmware update to be made to the connected Cyrus 

product. When updating the firmware in a PSU-XR always 

check if there is an update available for the connected 

Cyrus product at the same time and update if necessary.
