Isolated Serial Converter RS232 / RS485 or RS422 - DAT3580

Product Overview

The DAT3580 is a versatile and robust isolated interface converter designed to bridge asynchronous serial communication lines RS232 and RS485 or RS422. This device ensures complete isolation between the power supply and the RS-232 and RS-485/422 serial lines, effectively eliminating potential ground-loop issues. This makes the DAT3580 ideal for use in demanding environmental conditions. The converter supports both RS-422 full-duplex (4-wire) and RS485 half-duplex (2-wire) operations, with a transmission speed of up to 115.2 Kbps. Notably, the transmission is asynchronous, which means there’s no need for protocol, data format, or baud rate configuration. Additionally, RS-232 connections do not require handshake commands (like RTS, CTS) to manage the baud rate.

Installation Guidelines

To ensure optimal performance and longevity of the DAT3580, follow these installation instructions:

• Mounting Position: The device is designed for vertical installation on DIN rails.
• Spacing and Ventilation: If the panel temperature exceeds 45°C or if a high power supply value is used (>27Vdc), maintain a minimum spacing of 5 mm between devices to allow for proper airflow. Avoid placing the device near heat-generating equipment.
• Vibration and Shielding: Install the DAT3580 in a vibration-free area and use shielded cables for signal connections to avoid interference from power signal cables.

Visual Indicators (LEDs)

The DAT3580 is equipped with LED indicators to provide real-time status updates:

• PWR (Green):

• ON: Indicates the device is powered.

• OFF: Indicates the device is not powered.

• FAST BLINK: Indicates data is being transmitted from the RS232 port (blink rate varies with baud-rate).

• TX (Red):

• OFF: No communication in progress.

• FAST BLINK: Indicates data is being received on the RS485/422 port (blink rate varies with baud-rate).

How to Order

When ordering the DAT3580, specify the required interface type (RS485 or RS422) and, if necessary, the optional 24Vac power supply.
