Moxa Opt8-RJ45 +, 8-Port RJ45 connection box RS-232 content_copy

The Moxa Opt8-RJ45+ is an 8-port RS-232 connection box that enables the connection of serial devices to multiport serial cards in industrial environments. It serves as an interface adapter, simplifying the cabling between a computer or control system equipped with a multiport serial card and multiple serial end devices. The box features eight RS-232 interfaces on the device side, implemented via 8-pin RJ45 connectors. On the card side, a VHDCI 68 connector is integrated, enabling direct connection to the multiport serial card. The connection box is designed for use in industrial applications where reliable and structured cabling is required.

Applications
The Opt8-RJ45+ is suitable for applications requiring the connection of multiple serial devices such as sensors, measuring instruments, industrial controls, or communication modules to a central system. It is commonly used in automation systems, machine building, process control, and industrial communication. The RJ45 connectors provide a standardized, robust, and easy-to-handle interface that integrates well into existing network infrastructures.

Functions and Features in Detail
Each of the eight ports features separate LED indicators for data transmission (TxD/RxD), visually displaying the communication status. This facilitates quick diagnosis of connection issues, as active data transmission is immediately visible. The box supports baud rates from 50 bps to 921.6 kbps, ensuring broad compatibility with various serial devices. The Opt8-RJ45+ model does not include integrated surge protection; this feature is only available in the OPT 8S model variant.

Technology Explained Simply
The RS-232 interface is a standard for serial data transmission used in many industrial and technical devices. The Opt8-RJ45+ acts as a bridge between the multiport serial card in the computer and the serial end devices. The RJ45 connectors provide a mechanically stable and electrically reliable connection, well-suited for industrial environments. The connection is made via a 1.5 m cable included in the delivery, linking the VHDCI 68 interface of the box to the DB62 (m) interface of the multiport serial card.

Compatibility and Accessories
The Opt8-RJ45+ is compatible with multiport serial cards featuring a VHDCI 68 connector. The RJ45 connectors allow connection to devices that also have RJ45 interfaces. The box is part of a series that also offers variants with DB9 and DB25 connectors, enabling flexible adaptation to different devices. The cable connection is model-dependent and specified for the VHDCI 68 variant as DB62 (m) ↔ DB62 (m/f).

Mounting and Installation
Installation involves connecting the connection box to the multiport serial card using the included 1.5 m cable. The RJ45 connectors are attached to the serial devices. The box is compact, with dimensions of 152.8 × 32.8 × 32 mm, and can be mounted, for example, on an enclosure or near the devices. The LED indicators allow for easy verification of connections during installation.

Operational Advantages
The Opt8-RJ45+ reduces cabling complexity by consolidating multiple serial connections into a central box. The visual indication of data transmission via TxD/RxD LEDs simplifies maintenance and troubleshooting. The use of RJ45 connectors provides a standardized and robust interface, proven effective in industrial environments. The box is designed for industrial applications and supports a wide range of baud rates, enhancing compatibility with various devices.

Manufacturer's Warranty
The connection box is delivered with a 1-year manufacturer's warranty, underscoring the product's quality and reliability.

Scope of Delivery
The delivery includes a Connection Box (model Opt8-RJ45+) and a 1.5 m connection cable. The cable connects the VHDCI 68 interface of the box to the DB62 (m) interface of the multiport serial card.
