Actisense OPTO-4 Opto-Isolated NMEA 0183 to RS232 Adapter

The Actisense OPTO-4 is an opto-isolated, bi-directional NMEA 0183 (RS422) to RS232 interface cable, also called an NMEA to RS232 adapter. It gives you a safe way to connect an NMEA 0183 system to a laptop PC or any device with a standard 9-pin RS232 port. The isolation protects the connected device, so potentially hazardous voltages on the NMEA 0183 bus do not damage the PC hardware, and it helps guard against ground loops.

The OPTO-4 suits noisy or commercial environments and gives system builders a fully shielded solution. It is port-powered from the PC, so installation is quick and simple. The over-moulded case provides excellent water resistance, and its small footprint makes it easy to fit into tight spaces.

Key Features:

• NMEA 0183 and RS232 compliant
• Full duplex (two-way) communication
• Supports all baud rates up to 115200 baud
• Over-moulded case with a narrow profile for small spaces
• Transient protection on the PC output line
• Opto-isolation providing 2000 volt protection on the PC input line
• Reverse voltage protection on the PC input line
• Current limited to protect against cable faults
• Port-powered, taking power from the PC port
• Fully shielded for superior noise rejection
