Installation and Power-Up

Serial Communication Tool Interface (RS-422 or Optional RS-485)

All SENTRY TIM-100/120s support an RS422/485 serial communication link for
communication with a process equipment or host computer. The TIM-100/120 can be
configured to operate using either a four-wire RS422 link (typical configuration) or a two-wire
RS485 link. This is factory set based on the configuration ordered. The communication
interface is the same regardless of which communication link is used.

For compliance with

CE

EMC standards when using the serial communications interface, PTI

cable P/N W020-50 should be used. The serial cable includes a ferrite core for suppression of
conducted RF energy. The user may also supply their own cable and ferrite. The ferrite core
suggested is PTI P/N #12282 with casing P/N #12283. A ferrite of equivalent specification
may be used.

RS-422 Link (Two Differential Pairs)

The RS-422 communication link uses a four wire (Tx+, Tx-, Rx+, Rx-) connection. Two wires
are used to send from the host; two wires are used to receive by the host. The serial
communication interface cable is a six-wire cable. The TIM-100/120 end of the cable is
crimped with a RJ-12, 6-pin male connector. The other end is maintained with labeled flying
leads.

RS-485 Link (Single Differential Pair)

The RS-485 communication link uses a two wire (Tx/Rx+, Tx/Rx-) connection. Two wires are
used for bi-directional data transmission. The serial communication interface cable is a six-
wire cable. The TIM-100/120 end of the cable is crimped with a RJ-12, 6-pin male connector.
The other end is maintained with labeled flying leads.
