The USB-232-K and USB-485-K are isolated USB to serial converter cables for computers which lack a serial port, or where an extra serial port is required.
Online PR News – 25-October-2016 – Fairport, NY – Saelig introduces the USB-232-K and USB-485-K, isolated USB to serial converter cables that are ideal for computers which do not have a serial port, or where an extra serial port is required. The USB-232-K is an isolated USB-to-RS232 converter, while the USB-485-K is an isolated USB-to-RS422 /485 converter. These 39” cables are distinctive in the marketplace in that each unit has a world-unique device ID which ensures that it appears under the same COM port number regardless of which USB port on a particular PC it is plugged into. This simplifies application software configuration and eliminates many tech support issues. Powered entirely from USB port using an internal isolated inverter, these converter cables can transmit signals at a data rate of up to 115kbps (USB-485-K) or 230kbps (USB-232-K). The supplied software drivers support Windows 98, ME, Win2000, WinXP, Vista, Win7, Win8, and Win10 (32 and 64 bit).
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 now available from their USA distributor Saelig Company, Inc.
