9.2. 9.2. Built Built
The RS-485 interface can use commands to control the indicator. The interface can
read weighing data or parameters and store parameters in the indicator.
The interface can connect 32 units maximum and a personal computer using a
communication cable.
Each unit is specified by an address appended to the command.
Specifications
Transmission system .........EIA RS-485, Asynchronous, bi-directional, half-duplex

Instructions for Use
When using a terminator, connect it to the SDA and SDB terminals using the
accessory resistor.
If there is no signal ground at the host computer, it is not necessary to use the SG
terminal.
If a shielded cable is used, connect the FG teminal to the shield line.
When connecting to the RS-232C, use a converter of an RS-232C/ RS-485 converter
avilable on a market.
Use a muitiple drop connection for command mode.
Do not use a multi-drop connection in stream mode or jet stream mode.
