[TimeWave-AEA] Best Way to Connect PK-232MBX to IC-756Pro2 ?

[Tony Hackenberg]

Hi,
 
I recently purchased a used AEA/Timewave PK-232MBX with upgrades.  What are
your recommendations on how best to connect this TNC up to my ICOM
IC-756ProII?
 
Based on my review of the pertinent documentation (Timewave manual, IC-756
ProII manual and various "how to" websites), I've decided that there are 2
basic ways to interface the PK-232MBX with the IC-756 ProII:
 

1.	Microphone connection.  Use a cable to connect the TNC to the
756ProII's microphone connector (8-pin round) and a audio cable to the
external speaker jack);
Same as above but avoid the separate audio cable by taking the RX audio from
pin #8 on the mic connector; or 

2.	ACC(1) connection.  Use a cable to connect the TNC to the 756ProII's
ACC(1) socket (8-pin);
Same as above but use a second cable to connect the TNC's FSK socket to
other pins in the ACC(1) socket;

My gut reaction is that the ACC(1) connection is probably the best way to
connect the TNC to the 756ProII.  What are your recommendations and why?
