Exar Unveils Industry's First Single and Dual-Channel UART with Integrated RS-485 Transceiver Product Family -- Supports 8Mbps

Wed, 06 Jun 2007 20:38:20 +0200

The XR19L402/400 series offers different packaging and modem interface options. Both devices can operate in four different modes: active, partial sleep, full sleep and Power-Save. Each mode can be invoked via hardware or software. Upon power-up, the device is in the active mode where the UART and RS-485 transceiver function normally. In the partial sleep mode, the internal crystal oscillator of the UART, or the charge pump of the RS-485 transceiver, is turned off

The two-component light screen enables simple commissioning. The signal processor is entirely integrated in the receiver housing and can be configured via six DIP switches. A 3-digit display and a LED bargraph indicate the status and the orientation of the emitter and the receiver. If required, the configuration can also be implemented with the delivered software.

B&B Electronics releases Zlinx Radio Modems

Sun, 03 Jun 2007 20:38:20 +0200

Zlinx solutions operate within the ISM and 2.4 GHz frequencies. Coupled with extraordinary receiver sensitivity, this radio modem can full-duplex over long distances and through the most difficult environments. Special filtering technology blocks cell phone, pager and other wireless interference. The modem can operate from 9600 bps to 115.2kbps and transfers RS-232/422/485 serial signals. Its over-the-air data rate is 115kbps.

Sealevel Systems Announces Optically Isolated USB to RS-232/422/485 Adapters with New SeaLATCH Connector

Sat, 26 May 2007 05:52:16 +0200

Installation and setup is easy. Simply install the included software and then connect the serial adapter to your USB port. SeaLINK serial ports appear as standard COM ports to the host system enabling compatibility with legacy software. SeaLINK serial adapters are USB bus powered eliminating the need for external power supplies. Status LEDs display transmit and receive activity, and SeaLINK serial adapters support data rates to 921.6K bps.

In addition the non-isolated cards feature an eight times baud rate multiplier allowing operation up to 921.6K baud. The SIO-485/CF card also features automatic RS-485 tri-state line drivers and can operate in RS-485 mode without any special software...

RS-485 Transceivers Boast Switchable Termination, High ESD Protection

Thu, 12 Apr 2007 04:13:08 +0200

The LTC2854 and LTC2855 complement the existing LTC2859/LTC2861 transceivers, which operate from 5-V supplies. RS-485 networks require users to install 120-Ohm termination resistors, based on the physical layout of the twisted-pair wires and the placement of the nodes. If the bus is extended or reconfigured, the end user must change the termination again. By switching the integrated termination on or off under software control, the new transceivers allows the proper nodes to be terminated without the end user’s physical intervention.

Power-stingy RS-485 UARTs support Windows CE

Tue, 10 Apr 2007 04:13:08 +0200

Exar says the chips can operate in four different power modes -- active, partial sleep, full sleep, and power-save -- that can be invoked either via hardware or software. The chips power up in the active mode with normal UART and RS-485 transceiver functionality. In the partial sleep mode, either the internal crystal oscillator or the RS-485 charge pump is turned off. In full sleep mode, both the oscillator and the charge pump are turned off.

Innovative 32X Optical Zoom Lens Camera

Wed, 04 Apr 2007 04:13:08 +0200

When the RS-485 control is used, as many as 128 cameras can be controlled by one DVR or SSC-1000/SSC-2000 controllers. The SCC-RC130 (single camera, wired remote) can control zoom, focus and access the menu and is typically used in smaller installations.
