that all signals that are outputs be connected. The Model

9SPOP2 derives power from these signals, even if they

are not used by your system.

On a DTE device with a DB9 pin connector, the following

lines are outputs:

3-TX (Transmit)

4 DTR (Data Terminal Ready)

7 RTS (Request To Send)

Typical DTE devices include PCs, terminals, and printers. Typical DCE devices include modems and multiplexers. Most

DTE ports are male and most DCE ports are female. If the 9SPOP2 is inserted into a working system, it will only pass

signals if inserted correctly. If the devices communicate with each other without the 9SPOP2 inline, but not when it is

installed, simply reverse the isolator.

If your port meets the low voltage requirements of RS-562, you will not be able to use this isolator. An RS-562 port will

only produce about 3.7 volts, which is not adequate to power the isolator. Typically the only devices that have this type

of port are palmtop or very low power laptop computers.
