Device-side Pin Assignments for IU-100, IU-110, and IU-120

This information is applicable to the following Synchrotech part numbers.

• USB-SIO-IU-100
• USB-SIO-IU-110
• USB-SIO-IU-120

These USB to serial devices feature DB9 connectors, frequently used in RS-232 applications. RS-422 and RS-485 tend to use different connectors, so speciality cables (e.g. DB9 to Mini Din 8) are often needed to accommodate certain serial peripherals. The above image and following table should be helpful in selecting or designing application specific cables to deploy with the IU-1** series USB to Serial device.

Product updates: FarSite's FarSync Bit Error Rate Test (BERT) Testers

FarSite has been working to expand its Bit Error Rate Test (BERT) product line, and in accordance, there's been some changes. First, their stand-alone software package to upgrade existing FarSite Flex devices has been discontinued. Second, there's now a 2 port, 10 Mbits/s PCIe PCIe based BERT called the FarSync BERT Tester-PCIe. Lastly, the USB device that used to be called the FarSync BERT Tester, is now known as the FarSync BERT Tester-USB. In addition to adding compatibility with The Windows 8, the FarSync BERT Tester-USB adds the following new functionality.

• API for LabVIEW and Windows Applications
• Tests Manchester Encoding, Conditioned Di-phase
• Correction for balanced pair signals being connected the wrong way round
• Audible Alerts on Errors
• RS485 4 wire support
• Uses the FarSync Flex v2

Best in Class for Court Reporters and Stenographers

Court reporters and stenographers often deploy steno machines featuring RS-232 Serial ports (often called COM ports in Windows-speak). Some transcription software packages for court reporters and stenographers require hardware keys that are RS-232 Serial port based as well. In many cases, USB to Serial devices don't work with steno machines or transcription software package hardware keys. In the past, a PC Card based RS-232 adapter was the optimal solution for notebook computers to interface with these devices.

With the transition to ExpressCard slots on notebook computers, there a number of ExpressCard to RS-232 serial adapters that don't work because they utilize the USB portion of the ExpressCard standard. As mentioned above, USB to Serial devices typically don't work with steno machines or transcription software package hardware keys. Fortunately there is a solution to this situation. Synchrotech offers the Quatech Performance PCIe based RS-232 Serial ExpressCards. Being PCIe based, these ExpressCards are true RS-232 host adapters and don't exhibit the compatibility issues that USB based devices suffer from. For court reporters and stenographers with ExpressCard equipped notebook computers needing to interface with RS-232 Serial ports on steno machines or transcription software package hardware keys, PCIe based RS-232 ExpressCards are the perfect solution.

Performance PCIe based RS-422/RS-485 Serial ExpressCards

Synchrotech is now offering Quatech's 1, 2, and 4 port PCIe based ExpressCard to RS-422 and RS-485 Serial host adapters. Advantages of a PCIe-based ExpressCard design are in the interface to the laptop's motherboard. The PCIe bus interface is the successor to the PCI bus, which in turn was the successor to the ISA bus to which built-in serial ports were originally attached. As such, the ExpressCard adapter design utilizes a PCIe-based design and can still directly use I/O space addresses and interrupts, thus more closely emulating built-in ports than can be done via USB-based design. Moreover, because there's no USB stack for the drivers to contend with, throughput can be higher and latency will be lower (considerably so in many cases). Due to improved data transfer rate, the ExpressCard is considerably more efficient for multi-tasking operations.
