Specifications

- Power supply : from COM port
- Max. Signal Rate : 250Kb
- Input : 4….30Volts (3mA internal limited ) (optocoupler)
- Output : RS232 (SG (pin 5) and TD (pin3) no isolation)
- Connection : Wire soldered on PCB (+ and – INPUT / + and – OUTPUT)
- Housing : plastic SUBD-9 hood (metal hood optional)

Applications

- Connect NMEA to RS232
- Connect RS232 to RS232 (without handshaking)
- Ground Loop Elimination

Description

- ISOLATION Receive Data
For isolation of receiving data (RD) use 1x OPTO-INTERFACE.

Connection:
Input + interface #1 to + NMEA output etc. Input – interface #1 to – NMEA output etc.

- ISOLATION Receive Data and Transmit Data
To isolate receiving (RD) and Transmitting data (TD) use 2x OPTO-INTERFACE.

Connection:
Output + interface #1 to input + interface #2. Output - interface #1 to input - interface #2
Input + interface #1 to output + interface #2. Input – interface #1 to output – interface #2.

Note

For 0-MODEM connection connect pin 1+4+6 and 7+8 of SUBD-9 connector
(in case handshaking can not be disabled in software/hardware)
