5.2 RS232 Interface

NavigatorTM balances are equipped with a bi-directional RS232 compatible interface for communication with printers and computers. When the balance is connected directly to a printer, displa yed data can be output at an y time by simply pressing PRINT, or by using the Auto Print feature.

Connecting the balance to a computer enables you to operate the balance from the computer , as well as receive data such as displayed weight, weighing mode, stability status, etc.

The following sections describe the hardware and software provided with the balance

Hardware

On the rear of the balance, the 9-pin male subminiature “D” connector is provided for interfacing to other devices. The pinout and pin connections are shown in the adjacent illustration.

The balance will not output any data unless pin 5 (CTS) is held in an ON state (+3 to +15 V dc). Interfaces not utilizing the CTS handshake may tie pin 5 to pin 6 to defeat it.

IMPORTANT: An Ohaus RS232 cable is required to operate with this balance. A standard RS232 cable will not work. See Accessories listed in paragraph 5.7.

Output Formats

Data output can be initiated in one of three ways: 1) By pressing PRINT; 2) Using the Auto Print feature; 3) Sending a print command (“P”) from a computer.

The output format is illustrated in the RS232 command table which follows.

1. GETTING TO KNO W Y OUR BALANCE

Please read through this section carefully, as it contains important information for safe and economical operation of your NavigatorTM balance.

1.1 Introduction

Thank you for deciding to purchase a NavigatorTM balance from Ohaus. This versatile, portable balance offers a high level of oper ating con v enience and useful functions to mak e accurate measurements usually obtained from higher priced laboratory instruments. A custom LCD panel has a large 6 digit, 7 segment display which indicates the weight value of an item being measured and a 6 character 14 segment displa y which spells out items selected in the men us. In addition, the display contains text which indicates the active operating mode of the balance. Arrow indicators in the display prompt the user as to what panel ke ys are to be pressed to initiate a change. Built-in RS232 communication is standard on all models and allows communication with printers or computers.

Panel controls are clearly marked as to their function with large zero and tare buttons on either side of the front panel. Operation and setup of the balance is straightforward and easy. Setup is simple with 4 cursor keys, str aightforward menus, and prompts that easily guide y ou through the process .

NavigatorTM is designed with contours for easy cleaning and has a sealed front panel and spill gutter to direct liquids off the balance. F or leveling purposes, all models are equipped with adjustable feet and a level indicator.

Behind your instrument stands OHAUS Corporation, a leading manufacturer of precision we ighing equipment. An Aftermarket Department with trained instrument technicians is dedicated to provide you with the f astest service possible in the ev ent y our instrument requires servicing. OHAUS Corporation also has a Customer Service Department to answer any inquiries regarding applications and accessories.

3.3 Calibration

Navigator balances offer a choice of two calibr ation methods: Span Calibr ation, and Linearity Calibration.

•

Span

- Span calibration ensures that the balance reads correctly within specifications using two weight values: z ero and a weight value at 50% of full capacity and or 100% of the balance’s full capacity .

proceeding.

• Linearity

- Linearity calibration minimizes deviation between actual and display ed weights within the balance’s weighing range . Three weight values are used: zero, a weight value at midpoint of the balance's weighing range, and a weight value at or near the balance’ s specified capacity.

Calibration Masses

Before beginning calibration, mak e sure masses are available . If you begin calibration and realize calibration masses are not available , exit the menu. The balance will retain previously stored calibration data. Calibration should be performed as necessary to ensure accurate weighing. Masses required to perf orm the procedures are listed in the adjacent table and are av ailab le as accessories.

NOTE:

On the rear of the balance, the 9-pin male subminiature “D” connector is provided f or interf acing to other devices. The pinout and pin connections are shown in the adjacent illustration.

The balance will not output any data unless pin 5 (CTS) is held in an ON state (+3 to +15 V dc). Interfaces not utilizing the CTS handshake may tie pin 5 to pin 6 to defeat it.

IMPORT ANT: An Ohaus RS232 cable is required to operate with this balance. A standard RS232 cable will not work. See Accessories listed in paragraph 5.7.

Output Formats

Data output can be initiated in one of three ways: 1) By pressing PRINT; 2) Using the Auto Print feature; 3) Sending a print command (“P”) from a computer.

The output format is illustrated in the table which follows .

switches may be installed as shown in the diagram. Momentary contact switches must be used.

RS232 Commands

All communication is accomplished using standard ASCII format. Char acters shown in the following table are acknowledged by the balance. Invalid command response "ES" error indicates the balance has not recognized the command. Commands sent to the balance must be terminated with a carriage return (CR) or carriage return-line line feed (CRLF). Data output by the balance is always terminated with a carriage return - line feed (CRLF).
