OHAUS RS232 Interface Kit Instruction Manual

OHAUS RS232 Interface Kit

Product Information

The RS232 Interface Kit is designed for use with Ohaus products such as Scout Pro, Traveler, and Navigator. It allows for communication between the balance and other devices such as computers or printers. The interface installation involves attaching the module to the underside of the balance.

Product Usage Instructions

1. Slide the Blank Cover to the rear.
2. Remove the Blank Cover.
3. Install the Interface Module.
4. Slide the Module forward.

Setup:
The default communication settings for the Ohaus Interface are 9600-8-N-1 or 24007-N-2. Verify these settings on the balance. Determine the RS232 parameters required for the connected printer or computer. Consult the documentation of the computer or printer for assistance if needed. If the parameters do not match, you need to change either the balance settings or the computer/printer settings. B) Once the interface is installed, the balance will recognize it and add relevant items to the menu. Configure the balance to the desired RS232 and printing parameters by referring to the balance User Manual.

Print:
Stable On/Off – A-Print Cont, On.Stbl, On.Acc*, 5sec, 15sec, 30sec, 60sec, Off

Note : Print and RS232 menu selections may vary between different balance series.

RS232:
Baud: 600, 1200, 2400, 4800, 9600, 19200 – Parity: 7-even, 7-odd, 7-none, 8-none – Stop: 1, 2 – Handshake: None, Xon-Xoff, RTS-CTS – End: Yes, No

Setup Definitions:
PRINT/Stable On:
Balance transmits stable data only. Balance repeatedly sends data as fast as possible. Balance automatically outputs data upon stability. Balance sends data every (xx) seconds. Only sends data when PRINT is pressed. Set parameters to match printer or computer.

Connection:
The RS232 Interface Kit cable terminates with a 9-pin Sub-D female connector. The active pins are: – Pin 2 = TXD – Pin 3 = RXD – Pin 5 = Ground – Pins 4 and 6 are connected for hardware handshake – Pin 7 = CTS – Pin 8 = RTS The Interface connector can be directly connected to a computer, an Ohaus printer, or many other printers.

Operation:
RS232 OUTPUT With the Adapter installed, the balance operates in one of the following three ways: 1. RS232 = On, Auto Print = Off, Stable = On or Off: Pressing PRINT will send the display data. IfStable is set to On, the balance will wait for a stable reading before sending data. 2. RS232 = On, Auto Print = On, Stable = On or Off: The balance will automatically send data based on the settings in the Menu. If Stable is set to On, only stable values will be sent. 3. RS232 = Off: The interface is turned off. This saves significant power during battery operation. Data sent from the  Interface is in standard ASCII format terminated with a [CRLF](carriage return line feed). The output format varies depending on the balance model.

INTRODUCTION

This Interface Kit is for use with the following Ohaus products: Scout Pro, Traveler, and Navigator.

INTERFACE INSTALLATION

Install the Interface module on the underside of the balance as shown.

Note : The appearance of your model may be different.

SETUP

1. A) The Ohaus Interface is preset to communicate using the following settings: 9600-8-N-1 or 2400- 7- N-2, please double-check the setting in the balance. Determine the RS232 parameters required for the printer or computer that is to be connected. See computer or printer documentation if assistance is required. If the parameters do not match, it will be necessary to change either the balance settings or the computer/printer settings.
2. B) Upon installation of the interface, the balance will recognize the RS232 Interface and add relevant items to the menu. Configure the balance to the desired RS232 and printing parameters; refer to the balance User Manual for assistance in using the menus.

CONNECTION

The RS232 Interface Kit cable terminates with a 9-pin Sub-D female connector. Active pins: Pin 2 = TXD, Pin 3 = RXD, Pin 5 = Ground, Pins 4 and 6 are connected for hardware handshake, Pin 7 = CTS, Pin 8 = RTS. The Interface connector will connect directly to a computer, an Ohaus printer, and many other printers.

OPERATION

RS232 OUTPUT
With the Adapter installed the balance will operate in one of the following three ways:

• RS232 = on, Auto Print = off, Stable = on or off Pressing PRINT will send the display data.
  If Stable is set to On, the balance will wait for a stable reading before sending data.

• RS232 = on, Auto Print = on, Stable = on or off
  The balance will automatically send data based on the settings in the Menu. If Stable is set to On, only stable values will be sent.

• RS232 = off
  The interface is turned off. During battery operation, this saves significant power.

Data sent from the Interface is in standard ASCII format terminated with a [CRLF] (carriage return-line feed). The output format is as follows:

Scout Pro (SPx) Output:
Output Format 1 (for the models 303/123/202/402/602/2001/6001/ 401FZH/601FZH/6000FZH):

Output String:

• [weight] 12 characters (right justified)
• [space] 1 character
• [unit] 5 characters
• [space] 1 character
• [stability indicator] 1 character; “?” when unstable,
• blank when stable [space]1 character
• [Legend]  10 character

Note: All of the fields have fixed length.

Output examples (space indicated by ‘*’):

Output Format 2 (for the models 401/601/6000):
