Serial Connector

Connect up to four RS-232/RS-422/RS-485 serial devices to the network.

Graphic displaying two icons: temperature and IP30 rating.

Industrial Design

Designed with a rugged IP30 rated housing, resistance to a high degree of vibration and shock, protection against ESD/EMI/surge, and operates within a wide operation temperature range -40° - 75° C (-40° – 167° F).

The illustration shows a network setup where a computer is connected to the link/act port of the TI-M12. Another connection from the TI-M42 serial port is indicated, with icons for an LED display, alarm, sensor, and scale. The connection lines are labeled RS-232, RS-422, and RS-485.
The illustration shows two images of the TI-M12. The front angle view is labeled with Grounding point, LED indicators, two 10/100Mbps ports, and four serial (DB-9) port. The back angle view is labeled with a grounding point, 6-pin removable terminal block, DIN-Rail mount, and wall mount.
