SI/F 2-wire Serial Interface
This 2-wire serial interface is for connecting F160 to peripheral equipment such as printers or
remote displays. No polarity is needed for this simple, low-cost installation.
A two-core parallel cable or a cabtyre cable (Wire with covering thickened for construction) may be
used for connection. When a two-core parallel cable or a cabtyre cable is used, the transmitting
distance is approximately 30m (32.8yds). When a two-core shielded twisted pair cable is used, the
transmitting distance is approximately 300m (328yds).
●
Connection
Up to 3 peripheral units can be connected in parallel.
It should not run along side AC or other high-voltage wiring. It may cause of malfunction.
Up to 3 remote small displays can be connected. The each display can display individual content
according to the selection.
These indicated above are examples for the connection of Remote small displays, Remote large
display and printer. Each display and printer can select the data individually.

About the auto print command
The F160 can output the auto print command to the printer or display connected to the SI/F.
The auto print command is output when the complete signal turns ON. Therefore, if the final and
over/under comparison is set at “comparison OFF,” the auto print command is not output.

Irrespective of this setting, information including net weight, gross weight, and
tare weight is always sent from the F160, and some devices connected to the
SI/F allow selection of the weight value displayed/printed on the device side. In
such a case, this setting is validated by setting the weight value displayed/printed
as controller display value.
