The RS485 interface termination can be done by short circuiting pin no. 19 and 20 at the desk and panel type enclosures or by jumper JP4 on the interface board within the stainless steel housing . These short circuits terminate the line with an internal termination resistor of 100

Ω.

The 20mA CL ASCII output is disabled by default. The connections should be made as given in figure 9.1 for enabling this output. (Enabled output is not available for 12 V DC instruments ).

9.2.3 Continuous Output Mode

The continuous output mode allows for a fast and continuous data export to connected peripheral devices. The output data structure is described in Appendix 2.

9.2.4 Host Mode

The indicator can communicate with a PC in host mode. You can upload or download data to the indicator by adjusting the related interface parameters within the FLINTEC IndFace software or using the command sets described in Appendix 3. This mode is convenient for process control applications which need not only the weight data, but also require some uploads / downloads and status control.

9.2.5 Print Mode

In the print mode you can select the print formats (parameter group [04-], see chapter 9.2.6). This format

– preferably the single line

– is convenient to use as weight data interface in legal for trade applications which require recording to the Alibi memory. The print mode is not available for more than one interface (see also overview in chapter 9.1).
