Perhaps this will help, not exactly the 850.

MY SETUP
The following information is specific to my current setup - connecting the
PK-232MBX ( and my DSP-2232) to the ACC port on the TS690S for AFSK AND FSK
OPERATIONS:
AFSK Operation:
----------------------------------------------------------------------------
----
TS690s PK232MBX Function (PIN Number)
ACC2 Pin
3 Receive Audio/AFSK IN (1)
8 Ground: Audio/PTT Common Return (4)
9 PTT (5)
11 Transmit Audio/AFSK OUT (2)
12 Cable Shield NC
----------------------------------------------------------------------------
----
Note 1:
I have NOT yet used the option to mute the microphone on data transmission
and the squelch option is not hooked up ( PK-232MBX PIN 3).
Note 2:
Ground pins 4 and 8 in ACC Port are directly connected inside the radio and
go directly to the rig's ground. PIN 12 on the other hand is connected to
ground via a 0.001 capacitor. Source: TS450/690 service manual.
FSK Operations:
I have these connection in place as well so that I can switch between AFSK
and FSK operation. You need to watch MARK POLARITY when connection to the
FSK jack on the PK-232MBX. If you connect up incorrectly, at least there is
a place in the KENWOOD MENU SYSTEM (menu 38) that allows you to change the
polarity sense of MARK so that you do not need to resolder the connection. I
did find that the MARK POLARITY in my PK-232MBX ( Menu 38 - ON for PK-232
using connection 4) was the REVERSE of that in my DSP-2232 (Menu 38 - OFF
for DSP-2232). Check your setup as it may be different than mine here! The
manual should tell you the polarity of MARK - if you have trouble finding it
let me know and I'll dig the info out for you.
