RS-232/422/485 SERIAL COMMUNICATION BOARDS

23:40

ACCES I/O Products, Inc., announces the release of a new family of PCI-104 serial communication boards: the 104I-COM-8SM Series. These PCI-104 boards feature a selection of eight, four, or two ports of field selectable RS-232, RS-422, and RS-485 asynchronous serial protocols on a port by port basis.

Ports are accessed via two 40-pin I DC type right angle header connectors. The 104I-COM-8SM Series are feature-rich and allow for the connection of multiple serial devices making them ideal for a variety of applications such as POS, gaming systems, retail, hospitality, automation, kiosks, defense industries, high-density networking, or any other application requiring the connection of RS-232/422/485 serial devices to a PCI-104 compatible system.

Each RS-232 port is capable of supporting data communication rates up to 921.6 kbps and implementing full modem control signals to ensure compatibility with a broad variety of serial devices. RS-422 and RS-485 modes support data communication speeds up to 1.8432 Mbps. Based on the XR1 7D158, the boards have eight enhanced 16550 compatible UART and include 64-byte transmit/receive FIFO buffers to decrease CPU loading, and protect against lost data in multi-tasking systems while maintaining 100% compatibility with all operating system COM port software.

ACCES offers the 104l-COM-8SM, 4SM, and 2SM in both standard and extended temperature versions ideal for outdoor applications, harsh industrial surroundings, or military use.

Available accessories include a broad range of ribbon cables and screw terminal boards for quick and easy connectivity. Special order items such as conformal coating, custom baud rates, custom software, and more are also available.

The 10I-COM-8SM family of boards is supported by all operating systems as standard serial ports. All boards include a free DOS, Linux, and Windows XP/Vista/7
compatible software package with sample programs and source code in ะก and Pascal for DOS, and Visual Basic, Delphi, C#, and Visual C++ for Windows.

Prices range from $169 to $299, depending on the model. Inquire about OEM and volume pricing.

All hardware comes with a 30 day, no-risk return policy, and a three year warranty.

Four channels 7" widescreen displays

ADDED

B&K Precision has expanded its digital storage oscilloscope (DSO) portfolio with the release of their new 2550 Series. This new series of scopes adds four two-channel models (2552, 2554, 2556, 2558) and four four-channel models (2553, 2555, 2557, 2559), ranging from 70 MHz to 300 MHz bandwidth with 2 GSa/s sampling rates and 24 kpts/Ch memory. These high performance digital oscilloscopes cover a wide range of applications in R&D, service and repair, and education at a cost-effective price point.



While maintaining a portable form factor, the 2550 Series introduces a significant increase in display size compared to typical 5.7" displays on economy scopes. The new models feature a widescreen 7" TFT color display that maximizes visibility of signals under test, which is a benefit for long waveform captures or four-channel acquisition.

All models in the 2550 Series offer powerful debugging tools such as digital filtering with adjustable limits, waveform recorder mode, pass/fail testing, advanced triggering capabilities, 32 automatic measurements, and a large internal storage for saving and recalling up to 20 different waveforms and 20 oscilloscope setups. The scopes can also perform five waveform math functions: add, subtract, multiply, divide, and FFT. Each DSO comes standard with LAN and USB interfaces supporting SCPI and USBTMC protocols for remote PC control. The provided PC software allows all scope parameters to be controlled via a PC without the need for programming. At no additional cost, high bandwidth passive probes (one per channel) are also included with each unit; 200 and 300 MHz models add selectable 50 ohm input impedance.

Other useful features include context-sensitive help menus, multilanguage interface, and the ability to disable the Auto Set button for training. Front and rear panel USB host ports are provided to quickly save setup and waveform data, screenshots, or CSV files to a USB flash drive. B&K Precision's 2550 Series oscilloscopes are all backed by a standard three year warranty. Prices range from $1,015 to $2,495.

INCREASED FREQ RANGE FOR ANALYZERS

23:02

HAMEG Instruments has increased the frequency range for all spectrum analyzers in its 1000 series from 1 GHz to 1.6 GHz. With the purchase of a HMS1000, HMS1010, or HMS1000E, HAMEG customers will experience an immediate increase of 60% more frequency range at no additional cost.



The latest firmware version (HAMEG_FW_HMS_2.022) is available at HAMEC.com for download. Install it and restart the instrument with the new performance.

This added value applies not only to new instruments, but to all products delivered since July 01, 2012. Equipment has been tested at the factory to ensure compliance with the new specifications, and can be upgraded accordingly.

The free upgrade to 1.6 GHz is also available for all HMS1000 products purchased prior to July 01, 2012. This is subject to the restriction that these instruments could not be tested at the factory to guarantee compliance with the expanded frequency range.

For a special price of just over US$200 (plus tax), HAMEG will perform a firmware upgrade to test and synchronize an instrument. This will guarantee correct measurement results, including the expanded frequency range.
