RS-232 to RS-232 Port-Powered Optical Isolator

MODEL 232SPOP4

The Model 232SPOP4 optically isolates four RS-232 lines. The isolator has a DB25S female connector on the DTE side and a DB25P male connector on the DCE side of the isolator. Signals pass through the isolator as follows:

PRODUCT INFORMATION

When connecting the Model 232SPOP4 it is recommended that all signals that are outputs be connected. The Model 232SPOPO4 derives power from these signals, even if they are not used by your system.

On a DTE device, with a DB25 pin connector, the following lines are outputs TD 2 , RTS 4 , DTE READY DTR 20

On a DCE device, with a DB25 pin connector, the following lines are outputs RD 3 , CTS 5 , DCE READY DSR 6 , RLSD CD 8

On a DB9 pin IBM compatible computer with a standard serial port the outputs are TD 3 , RTS 7 , DTE READY DTR 4

If you don't know if your ports are DTE or DCE disconnect the cables and connect a breakout box. Connect the breakout box to only one port at a time. When the output lines are in the idle condition, they will indicate a negative state. If the output lines are in a constant active condition, they will indicate the positive state. If the lines are inputs, the LEDs on the breakout box will not light.

If your port meets the low voltage requirements of RS-562, you will need to externally power the isolator. An RS-562 port will only produce about volts, which in not adequate to power the isolator.
