Actisense OPTO-4 NMEA 0183

Isolate an RS232 (PC) port to protect against ground
loops.

The Actisense PC Opto-Isolator Cable (OPTO-4)
provides an easy way to link an NMEA® 0183 device to an RS232 (PC)
serial port. Providing the necessary isolation to allow a PC (or
any other device with a standard full RS232 9-pin port) to meet the
latest NMEA 0183 input specification.

Actisense OPTO-4 NMEA 0183 Features:

• NMEA 0183 & RS232 compliant
• Full duplex (two-way) communication
• All baud rates up to 115200 Baud
• Overmoulded case with a narrow profi le for installing in 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; takes power from the PC port
• Fully shielded for superior noise rejection
