40°C to -25°C (104°F to -13°F). The RD-300 can monitor up to four scales (S1, S2, S3, S4), and is available for either AC or DC power. The following diagram illustrates the front panel of an RD-300 remote display. -

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. -

(not furnished) and mount the enclosure securely. The enclosure is hinged on the bottom side of the box. The installation environment is not critical, but the RD-300/RD-232 should be located as far as practical from major sources of electromagnetic interference (EMI) or radio frequency interference (RFI). Also, care must be taken to ensure that the front panel display is easily visible. -

All Models - AC - Service You will need a source of 117 VAC ± 10% 60 Hz. 1 Phase to power the RD-300/RD-232. The standard unit has an 8' #18-3 AWG polarized line cord. This can be plugged into a standard duplex receptacle if the RD-300/RD-232 is used in a dry area. -
Page 9: Indicator Setup
Common indicators are discussed below. • Rice Lake IQ series (600-700), IQ plus series (810 and 310*) - All of the IQ and IQ plus series indicators work with the setup for continuous output and have the Consolidated Controls output. The IQ plus 810 set in the stream mode has the same format as the Condec indicators. - Page 10 03/10/00. Use the Universal receiver for this meter. • Cardinal 738 and 748, Rice Lake IQ plus 310* - These indicators can be set up for either the “current loop” or “RS232”, using the “computer” setting (S3=10001010). The baud rate can be 1200, 2400, 4800, or 9600.
- Page 11 RD-300/RD-232, if , and only if, the output formatting exactly matches what the display has been programmed to accept. If a computer or terminal is going to be used with an RD-300/RD-232, the universal format is probably the easiest to use if the data is sent continuously. Several other meters have been interfaced for use with the RD-300/RD-232.

2.4.4 Configuring the RD-300/RD-232 The RD-300/RD-232 must be properly configured. To do this, you must know: • Which indicator? • What Baud Rate? • How does the display handle a loss of signal? • Are you going to use the universal mode? •... - Page 15 Tare weight only Table 2-6. SW2-6/7 Displayed Weight Settings The RD-300/RD-232 will display the data selected by SW2-6 and 7 regardless what is showing on the scale indicator. IF YOU ARE USING ANY OTHER METER SETTING, USE THE FOLLOWING SWITCH DATA ON PAGE 12.
- Page 16 SW2-5, either the last valid weight or all dashes. If no valid data is received after ten seconds, the RD-300/RD-232 initiates a power on reset, clear all data, read the switches, and waits for new data. For these meters SW2-4,5,6 and 7 have the following meanings:...

Make sure all wiring is per the manual and is properly terminated. APPLY POWER- The RD-300/RD-232 enters the power on clear mode. All status switches are read at this time and the unit is configured for baud rate, indicator type, and input signal type. The RD-300/RD-232 display goes through a power up sequence which provides valuable information about the operating condition and setup. - Page 18 If the RD-300/RD-232 is located in a wet, damp, or cold environment, it is suggested to use a silica gel desiccant or better yet, an antioxidant “snowball” made by Hoffman Enclosure Company. These products in the enclosure will greatly increase product reliability and performance.
