[TenTec] Model 311 Schematic or info?

[NZ8J]

Does anyone have a schematic of the Ten Tec model 311 band data converter or
the pin out for the DB 25 output connector on the 311?  I just bought a new
one from Ten Tec and it came with very limited instructions.  It works super
to auto bandswitch my Hercules II using the Orion with the supplied cable,
but I would like to see if I could  also control an antenna switch box using
the second  plug on the "Y" cable going to my Hercules.

Thanks
