BB-422LP25R Port-powered RS-232 to RS-422 Converter Features Extend RS-232 data signals up to 1.2 km (4,000 ft.) Converts RS-232 TD and RD to balanced RS-422 signals Data rate: up to 115.2 kbps baud Powered from RS-232 handshake lines - no power supply required Introduction Ordering Information Model BB-422LP25R converts unbalanced RS-232 signals to balanced RS-422 Model No. Description RS-232 Connector RS-422 Connector signals. Power is derived from the Transmit Data line (pin 2) and the Handshake Control lines (pins 4, 5, 6, 8, and 20). The converter can derive power from these BB-422LP25R RS-232 to RS-422 Converter DB25 Female DB25 Male lines when they are in the Positive or Negative voltage state. This permits the converter to be used in applications with no regard to software control of the handshake lines. If no handshake lines are available and all power must be derived from the Transmit Accessories Sold Separately Data line, the converter can drive limited cable lengths. A guide for this condition BB-232AMF5 - DB25 Male to DB25 Female, 1.8 m (6 ft) would be to drive only several hundred feet of transmission line and not to terminate BB-232AMM5 - DB25 Male to DB25 Male, 61.8 m (6 ft) the transmission line with a resistor of less than 1000 Ohms. When more handshake lines are available, longer lengths of cable can be driven. The converter has been tested at 115.2k baud with 1220 meters (4000 ft) of cable.
