Featurest • 1-way RS-232 input, 4-way 2-wire RS-485 or 2-way 4-wire RS-422/485 output • Max. distance without repeater is 1.2Km • Connecting 32 modules in one RS-485 bus without repeater • Baud rate auto switching from 50 to 230Kbps • 2.5kVrms digital isolation and 1kV power isolation • Polarity guard that prevents damage from reverse power connection and over voltage protection • Surge and lighting protection • Each channel on the device is driven by its own RS-485 driver • DIP switch settings for RS-485 2-wire and RS-422/485 4-wire mode • Terminal resistor at internal jumpers • 35mm DIN rail installation kit • FCC, CE, RoHS approved Application Most industrial computer systems come with standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range, and networking capabilities. The RS-422 and RS-485 standards overcome those limitations by using differential voltage lines for data and control signals. The BSC3153i converter lets you to take advantage of RS-422 and RS-485 on systems originally equipped with RS-232. Two independent RS-485 output channels have their own driver which can transmit signals over 1.2km distance on each channel thus each channel can be connected to a separate serial network. You do not need to change your PC's hardware or your software. The BSC3153i lets you easily build an industrial grade, long distance communication system with standard PC hardware. They extend the communication distance by 1.2km (4kft) or increase the maximum number of connected nodes by 32. The BSC3153i also provides the digital isolation for system protection Side View Back View Front View Power Company Website www.bluskyelectronics.com Product Website www.convertermodem.net
