Combined use of functions of EP-90 printer and functions of the balance

Date output, ID number, Sample number, xK Mode of EP-90 printer can be simultaneously used with any function of the balance that involves data output. At every mass data output, these EP-90’s functions operate the same way as when mass data is output by pressing the print key.

(e.g.) While formulation mode of the balance is used, if ID number and Sample number functions are ON, lines of ID/Sample numbers are inserted before each component mass value. Turn off EP-90’s functions if they are not desired for each component.

While weighed result is displayed on the balance, if PRINT key of EP-90 or PRINT key of the balance is pressed, the displayed value will be printed out with an indication of the weighing unit.

Depending on the balance series, additional data apart from weighed results such as calibration report, application measurement results, date and time may also be output to EP-90 for printing. The PRINT key of the balance or the balance's function menu should be used to output such items. Refer to the balance's operation manual for instructions.

5. Communication and Other Settings

5. Communication and Other Settings

In EP-90 electronic printer, five settings including three communication settings can be selected with the DIP switches. The default setting of the three communication settings are Shimadzu electronic balance standard settings. Therefore, the communication settings do not have to be changed to communicate with the balance. If any settings have been altered after the delivery, set them to meet the balance's communication settings.

When using EP-90 simultaneously with the balance's WindowsDirect function.

• Set the baud rate at 300.

• Command keys of EP-90 are not valid.

• Date output function of EP-90 is not available.

DIP Switches are mounted on the floor of the printer paper holder part. (See the figure) Remove the printer paper. Turn the power OFF before operating DIP switches. The new settings will be made effective when turning the power ON.

Caution

Turn the power OFF before operating DIP switches.
