DL-9SPOP2
RS232 Port Powered
Optical Isolator
|
|
This unit optically isolates both the RS-232 transmit and receive lines.
The isolator has a DB9S female
connector on the DTE side and a DB9P male connector on the DCE side.
Signals pass through the isolator as shown.
When connecting the Model DL-9SPOP2, it is recommended
that all signals that are outputs be connected. The Model
DL-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)
On a DCE device with a DB9 pin connector, the following
lines are outputs:
1 DCD (Data Carrier Detect)
2 RX (Receive)
6 DSR (Data Set Ready)
8 CTS (Clear 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.
NOTE: Connecting an external power supply to the handshake lines may damage the isolator. Contact
technical support for more information on connecting an external power supply to the handshake lines.
