Led lights
The 1541 Ultimate has several led lights located on the top and right on the board. The
description start from left to right, and then down.
Drive leds
(Green & Red)
Located between the left and middle button. The green led
is on if the 1541 Emulated drive is Enabled from the
Configuration menu and ready to be used.. The red led
flickers when the drive is accessed.
Board power led
(Orange)
The left most led located between the middle and right
button.
Network leds
(Green & Red)
Located between the middle and right button. When there
is an Ethernet link active the green led will light up
permanently (Link detected), even if the Ethernet interface
itself is disabled from the Configuration menu. The red led
will flicker while packets are detected on the network.
SDCard led
(Green)
Located directly below the SDCard slot. This led will
flicker when read/write operations are performed, but
strangely not when the directory is accessed.
When powering-up (or resetting) please keep your eye on the drive leds. They follow a
specific pattern, and each step may take a couple of seconds. Only start operating the
1541U or C64 once the cycle has completed (even when the cartridge menu is visible on
the C64).
Green led will start to burn
Red led will start to burn
Red led will stop burning
Green led will dim.
Also keep your eye on the SDCard led. While it is flickering, the 1541U is accessing the
SDCard, but at current I have no exact idea why it is accessing the SDCard. It probably is
doing a recursive search for the last used D64 image on the SDCard and mounting it.
This may take quite a while, depending on how many files and folders are present on the
SDCard. Please wait for it to finish, flickering will stop when it is done.
1541U buttons
The 1541 Ultimate has 3 red buttons which you can press to activate their predefined
functions. Based upon the mode of operation and settings in your Configuration screen,
the function they perform will vary, and details are covered in the appropriate section of
chapter ‘Modes of operation’.
