Similar to the 1261B TECSource Cable, but adds wiring for both the 4-wire RTD connection as well as operation to 10A. The cable is terminated with a DB-15 connector on the instrument end and bare tinned wires on the mount end for connections to non-Arroyo mounts.

A version of this cable, the 1262B TECSource Cable, is available which features DB-15 connectors on both ends of the cable.
