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 eith er 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 O p t io na l H ar dw a r e

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.

2 RD-300/RD-232 Installation & Operation Manual

2.0 Installation

The following section describes the installation procedures used with the RD-300/RD-232.

2.1 Mounting

The standard NEMA 4X enclosure is a JIC standard 8" X 6" pattern. It is app roximately 8" high, 9.5" wid e, 5.25" deep, and weighs 4 lb. Mounting is via four mounting holes on 8.75" horizontal by 4" vertical centers. Use 1/4" hardware (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.

2.2 Electrical Service Connections

2.2.1 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. If the environment around the RD-300/RD-232 is wet or dirty, use a “Bell Box” or other gasketed receptacle or hard wire the AC directly to the RD-300/RD232. The cord grip furnished is mounted in a hole suitable for 3/8" NPT fittings.

If you hard wire power to the RD-300/RD-232, you will use the three position connector marked TB-1(shown in Figure 2-2). Connect the L1 (Black or Hot) wire to terminal #1, the right hand terminal nearest the fuse. Strip the wire approximately 3/16". Use a small screw driver or ball point pin to press the white latch release. While holding the lever down, insert the wire and release the lever. Pull on the wire to assure a good connection. You must use #14 AWG or smaller wire. Strip an d insert the L2 (white or neutral) wire into TB1-3. Pull on the wi re to assure a good connection. Strip and insert the ground (green) wire into TB1-2. Pull on the wire to assure a good connection.

2.2.2 DC Models Voltages 6.2 - 18 VDC

The RD-300/RD-232 will also work on DC power. To use a DC power source between 10 and 18 VDC, connect the + DC source to terminal TB2-1 and the DC- source to terminal TB2-2 as shown in Figure 2-3. The current requirement is 30 mA without the backlight option and 160 mA with the LED backlight. If the unit has no backlight installed, then it will work with voltages of 6.6-24 VDC without modification. If the optional backlight is installed on the RD-300, the operating voltage range is 8.2 to 18 VDC without modification. Consult the factory for other voltages.

2.3 Indicator Setup

Determine what indicator will supply the data to the RD-300/RD-232. Once determined, there are certain setup parameters which you will need to know. 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. The IQ plus 310 can match the format of several indicators: CARDINAL 738, WI 120, AN 5316, the Toledo Hi-Speed output, and Consolidated Controls (Condec). Match the baud rate you wish to use and program this into the RD-300/RD-232. Baud rates from 300 to 19,200 are supported. If the meter you are using has a selectable bit pattern, the preferred is 1 start bit, 8 data bits, and no parity. The RD-300/RD-232 will, however, receive 7 data bit patterns of any parity as well.

• Condec, Rice Lake IQ plus 310* - All models in the Consolidated Controls line should be set up for continuous output. Any baud rate from 300 to 38,400 is supported. Condec meters will work with either the Universal or Condec setting.

• AND Instruments 4322,4321,4316, - These indicators can be set up for either “current loop” (passive) or “RS232”, using the “stream mode” at 2400 baud, Format 1. The RS-232 can be used with either the Universal receiver or the AND setting. The passive current loop input requires the current supply from the current loop output.

• AND Instruments Model 5000 - This indicator can supply either RS-232 or 20 mA active current loop. Configure port two to transmit continuously in the Condec format. Use the Condec setting for this meter.

• Weigh-Tronix 110 and 120 meters - with continuous data outputs - These indicators can be set up for either “current loop” or “RS232”, in the continuous mode. Baud rates from 300 - 38,400 are supported. Both new and old data formats are supported.

Note: a special EPROM may be required from Weigh-tronix for the required continuous serial output. Use the Universal mode or the Weigh-tronix setting with these indicators. Switch 7 can be used to control unwanted time out if very slow update rates are chosen.

• Weigh-Tronix Models WI-125 - Connect the RS-232 signals (TB2-1 is ground and TB2-2 is transmit data) to the RD-300/RD-232. Set the Serial String to Auto = ON and Broad = ON. Layout - 1=Display, 2=ASCII -13-10-3-End, End. Set the baud rate to match the baud rate selected in the meter.

• Weigh-Tronix Models WI-130 - There are two ports, one and two. Port one uses either RS-232 or RS-485. Port two uses either 20 mA current loop or RS-232. Select one of the two ports. Set handshaking to off. You must program a BASIC program to get the meter to send the data continuously.

Use the following steps to set up a basic ticket string.

1. Program the string as:
