Follow on Google News | Saelig Introduces Isolated USB to RS232/485 Converter Cables With World-Unique Device IDsThese 39" cables are distinctive in that each unit has a world-unique device ID. This ensures that it appears under the same COM port number whichever USB port on a PC it plugs in to.
By: Saelig Co. Inc. Many PCs and laptops today lack serial ports and are required to be used in situations where isolation is required for safety or for operational quality and thus a conventional interface converter cannot be used. These isolated converters are the solution in these circumstances. Isolation for both the USB-232-K and USB-485-K is 100% tested to 1500V AC RMS. Female screwlocks are provided on the DB-9 side, making them physically resemble a standard serial port. All the standard serial handshake lines are supported to allow for maximum compatibility. The USB-485-K performs automatic driver enable (ADE) automatically, activating the RS485 drive for each transmitted character and eliminating the need for the application software to provide RTS control. This can be overridden by grounding pin 9 of the DB9 connector to permanently enable the drive stage for RS422 (or 4-wire RS485 Master) applications. The USB port provides sufficient power for a full-spec RS422 or RS485 interface capable of driving termination resistors and long cables. The addition of an optional DB-9-to-XLR cable makes the USB-485-K ideal for use with many professional audio controllers. The USB-485-K converter plugs directly into the USB socket of a PC or laptop and the three pin XLR plug connects to the remote interface port of the controller allowing remote control using the audio equipment's software. The USB-232-K and USB-485-K converter cables are produced by KK Systems, Europe's foremost serial interface manufacturer, and are nowavailable from their USA distributor Saelig Company, Inc. Fairport NY. For detailed specifications, free technical assistance, or additional information, contact Saelig at (888)-7SAELIG, via email: info@saelig.com, or visit www.saelig.com. End
