Isolated RS-232 or RS-485 remote host connection
Isolated RS-485 TI to TI connection
32 with RS-232 remote host *
31 with RS-485 remote host
* 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
