1. Connectivity Over Radio ™ DL-3282 1200 Baud Modem The DL-3282 external modem is designed for SCADA markets which utilize slow speed data transfer modes. The DL-3282 is FCC refarming compliant when paired with the RNet ™ brand JSLM or COR ™ brand DL- 3400 telemetry radios. This transparent modem is designed to eliminate dribble bits, making it capable of sending Modbus Protocol messages. User programmable to operate at 1200 and 300 bps. Selectable operating modes: Bell 202 and 103. RS-232 compatible with standard RTS/CTS hardware handshaking capable of half or full duplex operation. Small size permits easy installation in a wide variety of applications. Internal LED aids troubleshooting. Flashing green indicates power and that the unit is operational. Solid red indicates transmit. Standardized interface making it configurable with all Dataradio COR radio products. Rugged design with two-year warranty and manufactured in the U.S.A.
