Includes all compatible devices, such as an MTS 407 Controller. A maximum of only nine transducer
interfaces can be connected, because the addresses are limited to 1–9.
Maximum cable length
For RS-232 host:
50 ft from host to the first (nearest) TI,
and
300 ft from the first TI to the last SWIFT TI in the RS-
485 multidrop chain
For RS-485 host:
300 ft from host to the last (furthest) TI in the RS-485
multidrop chain
