1.1.1
Standard Software
The standard software for the RD-300 or RD-232 receives and displays serial data from 15 different types of
scale indicators. The receiver can accept either RS-232C or a 20 mA active or passive current loop. The standard
unit also re-transmits the data via a 20 mA active current loop. The data is transmitted either "as received" or in a
Condec continuous serial format at the incoming baud rate.
1.1.2
Standard Hardware
The standard RD-300 or RD-232 is comprised of a single circuit board housed in a JIC standard 8" X 6"
Fiberglass Reinforced Plastic (FRP) enclosure that is NEMA 4X rated.
Standard units are powered by either 117 VAC 50/60 Hz line power or DC voltages of 8.2 - 18 VDC. Voltages as
low as 6.0 VDC can be used to power the unit with the addition of one jumper.
1.1.3
Optional Hardware
Both the RD-300 and RD-232 can be ordered in a stainless steel NEMA 4X enclosure, an explosion-proof
NEMA 7CD, 9EFG, 4-enclosure panel mount, or as a board-only product for OEM applications. Consult the
factory for alternate enclosures.
An optional long-life LCD backlight is available for the RD-300. The LCD color is yellow/green and has a rated
life of 100,000 hours.
