Q: How is the 9-pin cable from the SE-2200, SE-2800 and SE-2850 keyboard control panel wired to the rack processor?
A: The SE-2200, SE-2800 and SE-2850 uses a 9-pin female to female straight through cable.
Datavideo only sells 1.5M replacement cables, part number G07690090016.
The cable is untwisted and unshielded.
Longer lengths may work up to 20M, but note that the cable carries power, so longer lengths can cause stability issues with voltage drop.
