EJ-03 RS-232C Serial Interface   

 

The EJ-03 allows an EJ-123, EJ-303, EJ-1202, EJ-3002 or EJ-54D2 balance to be 
connected to a printer or a personal computer using the RS-232C serial interface. 

  The RS-232C serial interface has the following four modes: 

Stream mode

................... 

Outputs data continuously. 

Key mode

 .......................... 

Outputs data when the    PRINT    key is pressed. 

Auto-print mode

 ............. 

Outputs data which meets the conditions of auto-print. 

Command mode

 ............ 

Controls the balance using commands from a personal 
computer. 

  Set the parameters of the data format (

bp5

 and 

btpr

) and data output mode (

prt

), 

as necessary. 

  Use a D-Sub 9-pin cable (straight type) to connect the balance to a personal 

computer. 
Optional cable: AX-KO2466-200    D-Sub 9-pin - D-Sub 9-pin cable (2 m) 

Installing the EJ-03 

1.  Turn the balance off and disconnect the AC 

adapter if used. 

2.  Remove the cover of the option slot on the rear 

by pressing and lowering it down. 

3.  Connect the connector in the slot to the EJ-03 

unit and insert it into the slot. 

4.  Secure the EJ-03 with the screws supplied with 

the option.
