BS232 T9 RS-232 optical isolator is used to isolat e RS-232 port. BS232T9 . The female DB-9 port
should be connected to a computer ’ s RS-232 port. The male DB-9 port connects to a device ’ s RS-
232 port. BS232T9 particularly suited to device ’ s RS - 232 port, especially which signal level is too low
or driving ability is too weak but needs isolation to computer ’ s RS - 232 port.
BS232T9 is the world's only built-in DC/DC isolation & port powered RS - 232 isolator..

BS232T9 ’ s male DB-9 RS-232 port has driving ability . Test can be achieved by the
following methods: 1, Plug female DB-9 to PC, you can use a voltmeter to measure pin of
TXD to GND of male DB-9 .It is about - 9 v voltage. 2, Plug female DB-9 to PC, and short
connect male DB-9 ‘ s TXD ( pin 3 ) to RXD (pin 2 ) , you can receive the data just sen t . 3,
BS232T9 can be either a single or in pairs.
BS232T9 needs no power supply, the isolation voltage 2500 v,.
BS232T9 baud rate is up to 192 00 bps , actually 28800 bps in short distance .
BS232T9 built-in 600 w anti lightning surge protector.
