The ACC port pinouts for the IC-746Pro are on p21 of the PDF manual.
If you actually have an IC-746 you'd need the correct manual (which I
assume is online if you google hard enough). I expect the ACC ports
are the same because they are pretty much the same across Icoms, at
least the pre-USB models. VSEND had to go to ACC(2) because HSEND was
on pin 3 of ACC(1) already. A better question might be "why did they
need two PTT lines" but I don't have an answer.
If you use the 6-pin mini-DIN "DATA" port there appears to be only a
single PTT. It's truly a pity that the industry never got behind this
standard (see http://www.wa8lmf.net/6-Pin-MiniDin-Data-Connector/index.htm).
The IC-746Pro dates from about 2001. I don't believe the non-Pro was
out for more than a year or two before the Pro came out. The only
difference that I know of is that the Pro has DSP filtering while the
non-Pro requires a fleet of FL filters.
