Dwyer Instruments: Series 350, Mother Node Communication Signal Converter
Converts RS-232 to RS-485, Isolates & Repeats
The Mother Node™ Communication Signal Converter line of RS-232 to RS-485 converters offers an easy way to use virtually any PC to communicate with half duplex RS-485 devices. Complicated hand-shaking issues are eliminated with these easy to use converters. The Mother Node™ converters come in three levels of sophistication to offer the exact combination of features you need. The Mother Node™ Silver Converter is a low cost device that converts signals at baud rates to 19.2 KBaud. Installation is simple, just connect the two RS-485 wires, the quick connect RS-232 cable, and the power transformer. No additional connections or settings are required. The Mother Node™ Gold Converter adds optical isolation and an additional quick connect (RJ-11) RS-485 output. The Mother Node™ Platinum Converter adds the ability to operate as either a converter or a RS-485 repeater. In repeater mode the RS-485 standard of 32 devices and 1800 m (6000 ft.) of cable run can be increased. In place of the 32nd device on the line, the Mother Node™ Platinum Converter reforms and repeats the wave forms to add an additional 32 devices and 1800 m (6000 ft.) of cable. When used with Love Controls products with Option 992, you can address up to 1020 devices on a single port.
