KPA1500 Wake On Lan not working

[Peter W2IRT]

Wake On LAN is not functioning on my KPA-1500 using the remote software. I
have the Wake On Lan and DHCP boxes checked in the Network tab in the
configuration settings within the KPA1500 Utility program, and the LAN
settings (including the IP address) are correct.

 
The only condition in which the remote software (v1.27) can find the KPA1500
is when the amp is manually powered on, after which it operates fine. Once I
power down the amp there is no condition in which I can reattach the
software remotely-I must power the amp on from the front panel button. In
addition to this, just pressing the "connect" button won't do it either. I
have to press the TEST button, wait until it finds the amp, then press
CONNECT and it connects normally.

 

At the moment this isn't a deal breaker, but I intend to remote the amp next
week to a relatively inaccessible space in the basement so I'd like to get
this solved as soon as possible.

 

As a side issue, the DHCP IP address had changed at some point, and the
remote software did NOT pick up the change. I had to hunt in my router for
the MAC address and enter the new IPV4 address manually into the remote
software.

Please and thanks.

If needed, the KPA1500 can be remotely powered on and off by momentarily
grounding Pin 8 of the KPA1500 AUX port, however this will not work using
an unmodified KPAK3AUX cable, which has no connection to Pin 8.  However,
this "remote power on" feature is supported by the Y-BOX v2.x
<https://bit.ly/Y-BOX>, when connected to the amp with a straight 15-pin
cable (not the Elecraft KPA3AUX cable), as documented here:

https://www.kkn.net/~n6tv/Y-BOX/Features.html#Remote

However, I believe you have the original Y-BOX, v1.x, which doesn't have
this feature.

So in your case, follow the instructions for modifying the KPAK3AUX cable
to support remote power via a K3 macro, as documented in the section
titled *Using
a Remote Site KPA500 from the Control Site *in the *K3 Remote Owner's
Manual
<ftp://ftp.elecraft.com/K3-Remote/Manuals%20Downloads/K3%20Remote%20Owner's%20Manual%20%20Rev%20D.pdf>*.
However, the macro in the manual has an major error:  it omits the last
semicolon.  The correct macro is documented at the link above.
Electrically, you just have to connect KPAK3AUX cable Pin 11 (DIGOUT1) to
Pin 8 in the female end of the cable (the end that plugs into the amp. AUX
connector).

This assumes you're not using the DIGOUT1 line to activate an external
pre-amp like the Elecraft PR6-10.

As a final note, the KPA1500 won't work properly if you connect all 15 pins
between the K3 ACC and the KPA1500 AUX (same applies to KPA500).  And of
course, *never* connect a VGA monitor cable to any Elecraft connector (way
too many lines shorted to ground).  So your best bet would be to use a
15-pin M/F extension between the Y-BOX and the KPAK3AUX cable (after
modification).  Connect the AUX cable to the amp, and the extension to the
Y-BOX.  Then program the K3 macro as documented in the link above.

Assuming you remembered to click the "Apply" button in the KPA1500 Utility
after checking the Wake on LAN box, the KPA1500 Remote software still may
not connect to the amp *if the KPA1500 Utility is running at the same time*,
and still connected to the KPA1500 USB port (even if the KPA1500 is OFF).
So, exit the KPA1500 Utility first, or click the "Close Port" button.  Turn
off the KPA1500, then launch the KPA1500 Remote software and the Wake On
LAN feature should work OK, using either the "Local Connect" or "Host
Remote" tabs, and the *Ethernet* secondary-tab.  Either the TEST button or
the CONNECT button should wake up the amplifier if it is powered OFF.

I could only replicate that when the KPA1500 Utility was running at the
same time as the KPA1500 Remote software.  And it didn't always occur.

In addition to this, just pressing the "connect" button won't do it either.

I cannot replicate that.  Either button wakes up the amp once the IP
address and MAC address are stored.

I don't think the KPA1500 software can automatically find the amplifier's
new IP address by poking around your entire LAN, if that's what you're
thinking.

I had to hunt in my router for the MAC address and enter the new IPV4

The KPA1500's new IPV4 address is displayed on the amplifier's LCD display
(MENU:NET IP ADDRESS), so there's no need to look at your Router.  Of
course MENU:TECH MODE has to be ENABLED first, to see this entry.  The
KPA1500 Utility can also be used to see the same menu, using the OPERATE
tab.  Just remember to close the KPA1500 Utility before trying to use the
KPA1500 Remote software to wake up the amplifier.
