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.
Monitor and control multiple scales, scanners, terminals or other serial devices with a single PC. Economizes systems by connecting a PC port to several data sources – ideal for devices requiring only intermittent access. The first device to send captures the data path, locking out other lines. Data flow may also be software controlled using the RTS line. Data from the host PC is sent to all attached devices. Port combiners can be cascaded by connecting the master port of each successive unit to one of the slave ports of the preceding unit. Each additional port combiner adds one slave port to the system. Model 232PTC9 requires an external 12 VDC @ 100 mA power supply (sold separately).
Model 232MDS can be connected so two computers or terminals can use one modem without switching. This modem data splitter can combine two 25-pin DTE ports and connect them to a 25-pin DCE port. With B B SmartWorx’ serial port splitter you gain reliability by capturing data from one peripheral on redundant PCs. This serial RS-232 splitter can improve a system’s economy by sharing multiple PCs on a single peripheral.
Model 9PMDS connects two computers or terminals to one modem without switching. The splitter can combine two 9-pin DTE ports to one 9-pin DCE port. With B B SmartWorx’ serial port splitter you gain reliability by capturing data from one peripheral on redundant PCs. This serial RS-232 splitter can improve a system’s economy by sharing multiple PCs on a single peripheral.
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 (sold separately).
Model 232DRIO provides a low-cost, easy to use solution for RS-232 serial port to discrete relay output applications. It offers one optically isolated input and two relay outputs. The General Purpose Control Module can be used to sense external ON/OFF conditions and to control a variety of devices. The 232DRIO includes a CD ROM with an instruction manual and demonstration programs written in QuickBASIC and C/C .
ntelligent and versatile, Model 232BSS4 serial data switch provides communication to four devices from one serial port. Each port contains a dedicated UART and an 8K byte Transmit and Receive buffer, allowing each port’s data rate, data format, and protocol to be configured independently. The Master port can send and receive data from one Slave port while the other Slave ports continue to buffer data. The Master can also broadcast the same message to two or more Slave ports at once. The switch can also be configured to send data automatically to the Master port from each of the Slave ports when data is present with an optional preamble identifying the port. It can also provide two-way communications between the Master port and one Slave port at a time. Switching and control is accomplished through user defined three or four character command strings. These control sequences are stripped from the data stream, making the switch transparent to the Slave devices. Switches can be ca...
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.
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.
