Description

OPTO-4 Serial Opto Isolator Isolate an RS232 (PC) port to protect against ground loops. The OPTO-4 provides a safe and low cost way of connecting an NMEA 0183 system to a PC or any other device with a standard RS232 9-pin port. As a bi-directional NMEA 0183 to RS232 interface cable, the OPTO-4 utilises OPTO-isolation to protect the PC input and spike protection for the PC output, providing comprehensive isolation of PC hardware when connecting to an NMEA 0183 bus. If isolation in both directions is required, the Actisense USG-2 offers bi-directional isolation in a USB to RS422 (NMEA 0183) form. The Actisense design integrates an over-moulded case for excellent water resistance and a small footprint for installation into tight spaces. FEATURES One OPTO-isolated input One NMEA output Up to 115200 baud Port powered Shielded cable and case BENEFITS Protects PC from damage Water resistant cable. Ruggedized overmoulded case suitable for harsh environment Quick and easy to install Electrical NMEA Listener / Input Isolation - 2kV Opto-Isolation between Red / Black NMEA Input Pair and all other Connections NMEA Listener / Input Voltage - +/-15V Continuous Maximum +/-35V Max < 1 Second NMEA Listener / Input Signal Thresholds - Logic ‘0’ +2V to +15V, Logic ‘1’-15V to 0V NMEA Talker / Output Voltage & Current - Dependant on Host RS232 Interface. Typically +/-5V to +/-15V @ 10mA Max RS232 Voltage on Host - +/-7V to +/-15V RS232 Port Total Current Consumption - 2mA to 5mA depending on RS232 Voltage
