[Elecraft] KPA3 / KAT500 Remote Question

[WB9JPH]

Question . . . .

My station is in a 2nd floor loft.

The antenna coax cables come into the basement utility room and then up behind the plasterboard walls to my shack.

Will I be able to put the KAT 500 and KPA 3 in the basement utility room and control them by snaking an RS232 cable from the shack to the utility room through the PVC pipe that contains my coax?

If this will work are there any special considerations I need to be aware of?
