The time/date stamp will remain current until the balance power is interrupted. If power interruption occurs, reset the time

and date. To check the time or date registers to see if they are set properly, press 100 , Recall or 101 , Recall on the

keyboard.

2. To have the time and date sent, press 0 , Enter , 79 , Store .

3. To stop the time and date being sent, press 1 , Enter , 79 , Store .

OPTIONAL RS-232 PRINTERS

(Printers must be serial)

There are a few different models to choose from. Please contact Scientech or one of our representatives for more information. A

comprehensive manual is included with each printer when purchased. All printers are set for a 9600 baud rate. To change this

setting please see the printer manual and the RS-232 Front Panel Configuration section. The balance display contents can be

sent to the printer at any time by pressing the balance front panel SEND switch or pressing the Data Input Keyboard SEND

switch. Balances only communicate with serial printers.

Many other accessories are available. Please contact Scientech at 303-444-1361 or 800-525-0522 or email us at inst@scientech-

inc.com for more information.

RS-232 INTERFACE

NOTE: Scientech balances are DTE (computer) devices. If communicating to another DTE device (ie computer), a

special Scientech RS232 cable (PN10697) is required. If you are communicating to a DCE device (printer), a modem cable

is required. Scientech offers an optional modem cable (PN10170) for your convenience.

Your balance is equipped with a bi-directional RS-232 compatible interface. The interface is uni-directional (balance send only)

when the local control is set to ON. To enable the bi-directional interface, set the local control to OFF (see the following RS-232

Front Panel Configuration section). The RS-232 connector is a 9 pin D subminiature connector located on the balance rear

panel. The pinout and pin descriptions are shown in Figure 8. The ext reset, on pin 1, is deactivated on all balances carrying the

CE mark.

Figure 8 Connector Pinout

The balance will not output any information under any circumstances unless pin 8 (CTS) is held in an ON state (+3 to +15

VDC). Interfaces not utilizing the CTS handshake may tie pin 8 to pin 7 or pin 8 to pin 4 to defeat it.

This interface does not strictly adhere to the official RS-232 standard. However, it emulates what has become commonplace in

the microcomputer industry.

RS-232 FRONT PANEL CONFIGURATION

Before using the RS-232 feature of your balance, it is necessary to configure the interface properly for your application. The RS-

232 Configuration Mode allows you to set baud rate, front panel control, software protocol, parity, auto send, continuous send,

and display blanking. The balance is configured with defaults at the factory. The default modes are shown in parenthesis below.

It is not necessary to follow the entire configuration procedure if only one parameter is to be changed. Follow Steps 1 and 2, then

use the MODE switch to select the parameter to be changed, skipping the others. Select the desired setting using the SEND

switch, save the setting using the ZERO switch, then turn the balance off and then on again with the ON/OFF switch.
