Port Powered RS-232/485 Converters 485SD9R, 485SD9RJ, 485SD9TB 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 These port-powered, two channel converters allow your computer to ORDERING INFORMATION OPTIONAL communicate longer distances by converting TD and RD RS-232 lines MODEL RS-232 RS-485 OUTPUT POWER to RS-485 signals. RS-485 also provides multi-drop capability. NUMBER CONNECTOR CONNECTOR 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 driver when data is present on the RS-232 side. Control of the driver is 485SD9TB DB9 Female Terminal Block RS-485 2-wire ✔ automatic at speeds up to 115.2 kbps. Converters are powered by the RS-232 port DTR and RTS handshake lines. The unit is powered from the RS-232 data and handshake lines ACCESSORIES whether the lines are high or low. If the handshake lines are asserted 485PS2 - 120 VAC to 12 VDC power supply, 100 mA, tinned leads, USA (held High), and no termination is used, the port power efficiency is PS1EU-1000 - 220-240 VAC to 12 VDC power supply, 1A, tinned leads, Euro greatly increased. Less than 35mA is required to operate the converter CEEE7/7 plug plus the load current. No handshake line change is necessary to PS1UK-1000 - 220-240 VAC to 12 VDC power supply, 1A, tinned leads, control the data lines. The RS-485 driver is enabled with each bit UK BS-1353 plug of data. The RS-485 receiver is disabled when the driver is enabled 9PAMF6 - DB9 male to DB9 female adapter cable, 6 ft. (1.8 m) and is 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 Simply put, all RS-232 ports are not created equal. Many laptop PC’s, control an RS-485 driver with standard software and the RTS line. This for example, deliberately reduce power to the RS-232 port to save the is especially true in Windows and multi-tasking operating systems. With battery. And, if you are working at the distance limits of RS-422 or 485, Advantech B+B SmartWorx’ Automatic Send Data Control circuit, driver control you might need an extra boost. For the majority of applications though, is in the converter hardware, so you do not have to work with software at all. the converter’s port 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.
