DTN Seriel Cable Question

[Bob Hunt <RHunt.066@xxxxxxxxxxxxxxxx>]

A friend of mine has a DTN D7000 unit. We want to do a bit of
experimenting with the output from that box, but we don't want to be
cutting up the DTN supplied cable.

Would anyone happen to know if this is a standard cable that can be
purchased from other suppliers, or is this something specifically
wired for DTN purposes. If its specific to DTN, would anyone happen to
know where we might get a wiring schematic?

Thanks in advance,
Bob Hunt
