DTECH Serial RS232 Isolator Optocoupler Male to Fmale RS-232 Optical Isolation

Description

Serial RS232 Optical Isolator
Transceiver
Adapter Protect Your RS-232 Devices
Protects Your DCE and DTE Equipment Against Data Loss and Equipment Damage
2500Vrms or 500V DC isolation voltage effectively protecting your devices from ground loop noise, transient surges and lightning, etc.
Optically isolates three wire (TX, RX and GND signals) on both transmit and receive lines.
It features auto-sensing and self-adjusting that automatically adjusts the baud rate, up to 57600bps;
Port powered from RS-232 signal (TXD, RTS or DTR), no external power required.
Suitable for terminal devices using 3 wire system (TXD, RXD and GND), such as modem, router, multi-user system and satellite receiver, etc.
When you connect your PC to an RS232 device and the ground system is no good state but you don’t know of it, it may lead to your devices in damage and downtime in a hurry!
Or your project which requires 3 wire RS232 communication between devices ( says two PCB boards) have really huge ground loop noise that messes up the real signal.
If you have such annoying issues above, don't worry. Just put the RS-232 photoelectric isolator between your devices and it will provides effective protection against over-voltage and keeps the devices safe, then you can obtain reliable data communication.
S
imple Operation
Its female connector is wired as a DCE and should be connected to a DTE port. The male connector is a DTE and should be connected to a DCE port. If you are connecting a DTE to a DTE or a DCE to a DCE, a null modem cable will be needed (not included).
