I have it working!
Thanks to Joe (W4TV) for the help. I'd have never found menu #20 had he not
said it had to be set to "LIN". I was quite familiar with the menues but
didn't recall one that said CAT/LIN/TUN. On closer inspection I didn't have
a menu 20. I figured that it was probably something simple and turns out it
was, but not exactly apparent. An e-mail from Yaesu Tech Support said to go
to menu #1 and turn it ON. Menu #1 is "Extended Menues". Turning it on found
menu 20 visible and the default was CAT. Changing that to LIN and the auto
band switching now works. Now I can change the "-" in the menu # (for menu
20) to a "." and when Menu #1 is off Menu #20 will still be visible.
First for any one interested the pinout on the Yaesu 5-pin DIN connector on
the back of the HL-1.5HFX is as follows:
When looking at the 5 pin socket on the amp starting to the left of the gap
in the pins: NOTE the "gap is up" on the amp!
DATA, A, B, C, and D are sequential, with A being the upper left pin and
going counter clockwise around the socket. The last pin (upper right) would
be transmit inhibit. which ties to pin 3 and 8 in the 8-pin mini DIN
connector on the 897D
In the data cable there are no connections to pin 1 (+13V) and 2 (Amp
keying)
You do have to connect pin 2 of the mini-DIN and ground to a short cable
with a RCA plug for keying the amp. Pin 1 is not used.
I found two 10' Apple printer cables and a 5 foot APC cable on Amazon for a
total of $7.72. These have wires to all 8 pins and they are color coded IF
you start with black = 1 instead of 0.. They have the molded computer
connectors and require shaving/sanding/filing (or what ever) to remove the
corners so the plugs fit into the openings on the back of the 897D. Sanding
an all they still make a nice looking cable.
The best price I found on the male, 8-pin mini-DIN connetors was just shy of
$7.00 and I'd still have had to make the cables. I cut 2'6" off one of the
10' cables. I used that to make the auto-band switching and amp keying
cable. The other piece is now an amp keying cable for my Henry 2K4 just in
case I need the extra heat in the shop this winter.

Menu #20 solved this as the socket is switched between CAT, LIN, and TUN.
Now I can move on to adjusting the antenna which works great on 6-meters as
well as the very bottom of 40.
