Overview & IsolationModel BB-232SPHI4 isolates and protects RS-232 equipment from lightning surges, accidental high voltage shorts and ground loops. The isolator provides 4000 Volts isolation between sides ó twice the rating of many isolators. The two sides of the isolator are powered independently to maintain isolation.
Model BB-232SPHI4 supports RS-232 data signals up to 115.2 kbps as well as RTS and CTS handshake lines. DTE device connections are made through a DB25 female. DCE device connections are made through a DB-25 male.
Power Options – handshake lines, low-power ports, external power
Both sides of the isolator can draw power from the RS-232 data and handshake lines, eliminating external power source requirements for most systems.
Each side of the isolator can be powered independently. If the isolator is to be used with low power ports or when handshake lines are not available, external +12V power can be supplied to either side or both (power supply not included, sold separately). This versatile powering configuration minimizes the number of supplies required by the overall system.
Connections
When connecting Model BB-232SPHI4, it is recommended that all device signals be connected. The isolator derives power from these signals, even if they are not used by your system. On a computer with a standard DB-9M serial port, a 9-to-25 pin adapter can be used to connect the isolator
