Data Taps, Splitters, Combiners, Switches, Line Boosters

Whether you need serial data taps, testers, port splitters, line boosters or port combiners, these simpler technology tools can help you complete your communications system.

  • BB-232BSS4

    The BB-232BSS4 switch communicates from 1 serial port to 4 devices. Each port has a UART and 8K TX/RX buffer - data rate, format and protocol can be configured separately. DB25 Master port configured as DCE. DB9 Slave ports configured as DTE (for modem, DCE devices). Null modem may be required.

  • BB-232CDT

    Tap in on a serial data stream and transparently feed another monitor, printer or other device. Model 232CDT has DIP switches that allow you to monitor the main Transmit and Receive lines individually or together. The male RS-232 connector on the top and the female RS-232 connector on the bottom are connected straight through, pin for pin. These connectors are used to connect the device – in series – with the RS-232 line to be tapped.

  • BB-232LB9R

    The 232LB9R is a 9-pin RS-232 repeater that re-transmits all 8 signals and carries the ground line through. Many computers, laptops and some desktops ship with low-power versions of RS-232 ports that are unable to drive port-powered devices or full-length RS-232 cabling. The 232LB9R can amplify these weak signals up to the RS-232 Standard for uses such as running port powered devices. It is also ideal for extending full-powered RS-232 cable runs beyond the typical 15 to 30 meters (50 to 100 feet) distance. An external power supply is required (not included, sold separately).

  • BB-232MSS2

    Model BB-232MSS2, RS-232 4-Port Mini-Smart Switch/Port Combiner, allows one RS-232 host device to connect to up to four RS-232 devices. Model BB-232MSS2 can function as a software and/or hardware controlled switch. There are four LEDs that indicate which port is connected to the master port. The master port can be configured as a DTE or DCE port by an internal switch setting (see datasheet). If the master port is configured as a DTE port, the four slave ports automatically become DCE ports. Handshake lines DSR and DTR are connected together and are not passed through to the master port. There is no delay through the device and data is not buffered. The communication format is set via dipswitch 1 (SW1 - see datasheet). NOTE: The data format and rates mentioned are used to switch Model BB-232MSS2. Communication between the devices can use any format or data rate. NOTE: Power supply required, not included, sold separately.

  • BB-232UDS

    Model 232UDS, universal serial data splitter, can be connected so that any two RS-232 devices can connect to any one RS-232 device. For example, two computers can share the same modem or serial printer at the same time and each can remain connected at all times. The other pins must be programmed for proper direction of data flow. Model 232UDS can function as either an modem data splitter or a printer data splitter. It allows you to switch select which lines are OR’d together and which lines are passed straight through. This unit is self-powered from the RS-232 line and can be left permanently installed.

  • BB-9PCDT

    Tap in on a serial data stream and transparently feed another monitor, printer or other device. Model 9PCDT allows an RS-232 port to tap into and check data being transmitted between two other RS-232 ports. DIP switches set programming to monitor the main Transmit and Receive lines individually or together. Choose between monitoring the DCE or DTE port. Also allows the monitoring port to be either DTE or DCE. The DTE connector is male, and DCE and TAP connectors are female.

  • BB-9PMDS

    Model 9PMDS connects two computers or terminals to one modem without switching. The RS-232 splitter can combine two 9-pin DTE ports to one 9-pin DCE port. Gain reliability by capturing data from one peripheral on redundant PCs. This splitter can improve system economy by sharing multiple PCs on a
