Product information

Description

The TRENDnet TI-M42 Industrial Modbus Gateway with 4 Serial Ports and 10, 100 Mbit/s Ethernet LAN is a robust networking solution designed to bridge traditional serial equipment with modern Ethernet infrastructures. Engineered for demanding industrial settings, this Modbus gateway enables reliable serial-to-Ethernet communication, ensuring seamless data transmission across your automation network.

Advantages

This industrial gateway features a rugged IP30-rated housing that offers protection in harsh operating conditions, combined with high resistance to vibration and shock as well as ESD, EMI, and surge protection. It supports flexible deployment through wall or DIN-rail mounting options. With a wide operating temperature range, it functions reliably in extreme environments. The device allows you to connect up to four serial devices simultaneously while supporting multiple serial interface types and flexible configuration options via web management or telnet.

Suitable for

  • Connecting legacy RS-232, RS-422, or RS-485 serial devices to an IP network
  • Industrial automation and process control environments
  • Modbus RTU and Modbus ASCII network integration
  • Factory and warehouse machinery communication

When it may not be suitable

This device is not designed for standard consumer or home networking use where industrial-grade physical protection and multi-port serial connectivity are unnecessary. It also does not support gigabit Ethernet speeds, making it unsuitable for applications requiring high-bandwidth data transfers.

Key specifications

  • 4 x Serial DB-9 ports supporting RS-232, RS-422, and RS-485 interfaces
  • 10, 100 Mbit/s Ethernet LAN interface with RJ45 connector and Auto-MDI/MDIX
  • Complies with IEEE 802.3, IEEE 802.3u, and IEEE 802.3x networking standards
  • IP30 rated industrial housing in black
  • Serial port baud rate ranging from 50 bps to 921.6 Kbps
  • Input voltage of 48 V with a maximum power consumption of 3.84 W
  • Compact dimensions of 103.5 x 81.5 x 32 mm

How to use

Mount the gateway securely onto a DIN rail or wall within your designated industrial setup. Connect your power source supplying the required input voltage. Attach your serial devices to the DB-9 ports using appropriate cables, and connect the Ethernet port to your local network using standard cabling. Access the device management interface via a web browser or telnet to configure network settings, IP addresses, and serial parameters according to your network requirements.

What to consider before purchase

  • Verify that your serial equipment utilizes RS-232, RS-422, or RS-485 interfaces
  • Ensure your network infrastructure matches the 10/100 Mbit/s Ethernet capability
  • Check power supply availability for the required input voltage
  • Confirm operating environment conditions align with the industrial specifications
Ensure proper grounding and follow all local electrical codes when installing industrial networking equipment in demanding environments.
All features
Interface: Interface ports to connect pieces of equipment. USB (Universal Serial Bus) has become the most popular wired interface to connect peripherals. USB 2.0 supports speeds up to 480 Mbit/s (USB 1: 12 Mbit/s). The interface FireWire is also known as the IEEE 1394 standard. Enhanced IDE (EIDE)is sometimes referred to as Fast ATA, Fast IDE or ATA-2.
4 x Serial (DB-9) ports
Weight: Weight of the product without packaging (net weight). If possible, the net weight is given including standard accessories and supplies. Please note that sometimes the manufacturer leaves out the weight of accessories and/or supplies.
0.512 kg
Operating relative humidity (H-H):
0 - 95
Operating temperature (T-T): The minimum and maximum temperatures at which the product can be safely operated.
-40 - 75
Serial interface type:
RS-232/422/485
Height: The measurement of the product from head to foot or from base to top.
32 mm
Input voltage: The voltage (V) which is required to power the product.
48
LED indicators:
Y
Width: The measurement or extent of something from side to side.
103.5 mm
Depth: The distance from the front to the back of something.
81.5 mm
Product colour: The colour e.g. red, blue, green, black, white.
Black
Networking standards: The way in which the network is working, e.g. IEEE 802.11a, IEEE 802.11b, IEEE 802.11g.
IEEE 802.3x, IEEE 802.3u, IEEE 802.3
MAC address filtering: Security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists.
Yes
RS-232 ports: The number of sockets (ports) for RS-232. An RS-232 serial port was once a standard feature of a personal computer, used for connections to modems, printers, mice, data storage, uninterruptible power supplies, and other peripheral devices. Now it has been largely replaced by USB and other ports.

Ethernet LAN data rates: The different speed levels of the Ethernet LAN connection.
100, 10
International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
IP30
Power consumption (max): The maximum amount of power used by the device.
3.84 W
