I am not familiar with the FT897D so I have just looked up the manual. I am an HRD enthusiast with the old TS570D.
You need two cables:
1) To control the rig you need a cable from a RS232 com port on a PC to the 8pin mini DIN CAT/LIN connector. The com port could be built in on an older PC or one of those USB to serial converters for a new PC. Make sure you match the bps (baud) setting in HRD and the rig.
2) To use the Digital Master 780 data / sstv software, you need to connect the 6 pin Data Jack to the sound card. On most rigs it is necessary to do this through isolating (audio) transformers (or opto isolators) to avoid hum earth loops otherwise you will radiate a very poor broad signal.
It is also usual to use the PTT line on the Data Jack to control the transmitter from one of the control lines on a PC com port (though it is possible to use Vox).
This means that cable 1 and cable 2 are not totally separate and cable 2 has transformers and a level converter in it! It just got more complex than a few wires and plugs.
So you end up making or buying an interface unit. It is not particularly complex but I would let someone else make those 6 and 8pin DIN cables
Names like G4ZLP, Rig Blaster, Tigertronics come to mind with varying prices and sophistication. TINAR.
Hope that helps.
