For Optec IFW or TCF-S. Hand control cable, RJ-45 to DB-9.
Custom length cost is $20 plus $1.95 per foot, so $21.95 is the minimum charge, which will show in your shopping cart ($20 handling fee and $1.95 for a foot of cable). Change the quantity in your shopping cart to whatever length cable you desire, and when you update your cart, the new price will be present. Make sure of this before you check out. Just to make sure we know your wishes, I would also put a note in the comments section that I ordered such-and-such feet of custom cable. Hey, you can't be too careful!
Note: Photo shows the 6-foot cable...yours would be longer :>)
