Summary 08059: deadconx, deadconxj: Dip switches are mislabled and misassigned.
Description Dip switches 2-7 and 2-8 are currently labeled "Number of Enemies 1/2 Player". The dip switches that control the kill count are actually 2-1 and 2-2. The relevant code for this starts at 0x015F46 in the main CPU - I've attached the disassembled code in a txt file.

The values of these dip switches are also incorrect. Currently, 0x01 is listed as 40/60, and 0x02 is listed as 25/45. These values should be reversed: 0x01 is 25/45, 0x02 is 40/60.
(The actual way this setting works is slightly more complicated than the static numbers listed and changes based on round - again, see the txt file.)

Dip switch 2-7 is unused, but dip switch 2-8 is the "Upright Controls" dip switch seen in other F2 sets. Setting it to "True" disables the second player.

Here's a dip sheet that seems to confirm this:, though it doesn't show the cabinet type dip. It seems it shows different values for the "life meter" dip than the ones in MAME.

There is Game Manual and Service Instructions for Dead Connection, but I don't see a scan of the originals online. You can see what they look like here:
I'm not sure where the handwritten table comes from.

This site has the DIP table copied from the Japanese manual.
The player life meter values match the numbers available in MAME, but differ from the handwritten table.
Note how it also lists DIP SW B - 8 for switching Double Control Panel - to Single Control Panel.

The sales flyer lists:
Players: 2 (2 can play at the same time, and a player can join in midway through)
Control Panel: 8, way . 2, buttons . double control panel

I would imagine that many operators in Japan would have wanted the option to install this board in a cocktail table with a single control panel. It would be interesting to see if the single control panel value would suppress the 2P select and join messages.

Fixed typos regarding switches 2-7 and 2-8 being listed as 2-6 and 2-7 respectively.

And yes, dip switch 2-8 suppresses the 2P Join message both at the top and on the push start button screen.
