Port Powered RS-232/485 Converters 485SD9R, 485SD9RJ, 485SD9TB www.advantech-bb.com PRODUCT FEATURES • Extend RS-232 data signals up to 1.2 km (4,000 ft.) • Change RS-232 TD and RD to RS-485 signals • Automatic Send Data Control - no software drivers necessary • Baud rates up to 115.2 kbps • Powered from RS-232 handshake lines - no power supply required 485SD9R shown These port-powered, two channel converters allow your computer to ORDERING INFORMATION OPTIONAL communicate longer distances by converting TD and RD RS-232 lines to MODEL RS-232 RS-485 OUTPUT POWER NUMBER CONNECTOR CONNECTOR RS-485 signals. RS-485 also provides multi-drop capability. SUPPLY 485SD9R DB9 Female DB9 Female RS-485 2-wire All converters feature Automatic Send Data Control which enables the 485SD9RJ DB9 Female RJ11 RS-485 2-wire 485SD9TB DB9 Female Terminal Block RS-485 2-wire ✔ driver when data is present on the RS-232 side. Control of the driver is automatic at speeds up to 115.2 kbps. The unit is powered from the RS-232 data and handshake lines whether ACCESSORIES the lines are high or low. No handshake line change is necessary to SM16-12-V-ST - Power Supply, 12 VDC 6 Watt, Stripped and Tinned, International control the data lines. The RS-485 driver is enabled with each bit of AC Input, International AC Blades data. The RS-485 receiver is disabled when the driver is enabled and is 9PAMF6 - DB9 male to DB9 female adapter cable, 6 ft. (1.8 m) enabled when the driver is disabled. Model 485SD9TB can be optionally powered by an external 12 VDC power supply. These converters are suitable for field service, where a power supply would add clutter, or anywhere you need compact, easy-to-use, economically priced serial conversion. Why use an “optional” power supply Automatic Send Data Control Explained with a port-powered converter? As operating systems become more complex, it is increasingly difficult to control Simply put, all RS-232 ports are not created equal. Many laptop PC’s, for an RS-485 driver with standard software and the RTS line. This is especially true example, deliberately reduce power to the RS-232 port to save the battery. in Windows and multi-tasking operating systems. With Advantech B+B SmartWorx’ And, if you are working at the distance limits of RS-422 or 485, you might need Automatic Send Data Control circuit, driver control is in the converter hardware, so an extra boost. For the majority of applications though, the converter’s port you do not have to work with software at all. powering is sufficient to accomplish the task. The circuit monitors data flow and enables the driver during transmission and automatically disables it when no data is being sent. There is no need to rework software or install new drivers. Most Advantech B+B SmartWorx RS-232 to RS- 485 converters and RS-485 serial cards include Automatic Send Data Control.
