Four-Pack Converter Adapters

The TRENDnet TI-S400 package supplies four RS232 to RS422/RS485 converter adapters. Each unit converts an RS232 port to an RS422/RS485 terminal block. The adapters are designed for use with TI-M12 and TI-M42 industrial Modbus gateways.

Industrial Gateway Installers

This pack suits engineers deploying TI-M12 or TI-M42 gateways who need multiple serial conversions in one purchase. It is not for buyers who require a single adapter, USB connectivity, or protocol support beyond RS422 and RS485 terminal blocks.

Plug-and-Play Terminal Blocks

Installation involves wiring the RS232 side to the host port and securing RS422/RS485 lines to the terminal block screws. No driver software is required. The most common issue is incorrect polarity on the differential pair, which prevents communication until the wires are swapped.

Questions about this item

What port must my equipment provide for the TI-S400 adapter to connect?

The adapter plugs into a DB9 RS232 serial port on your device.

Will the four adapters work with legacy RS422 or RS485 gear I already have?

Yes, each adapter converts the RS232 signal to an RS422/RS485 terminal block for older equipment.

How can I verify the TI-S400 pack is functioning after wiring it to a gateway?

Check that the gateway detects serial data on the RS422/RS485 terminals and that communication LEDs show activity.
