10. INTERFACE
10-1. 2-wire Serial Interface (SI/F)
This 2-wire serial interface is for connecting the F701-C to peripheral equipment such as a printer
or remote display. 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. When a two-core shielded twisted pair cable
is used, the transmitting distance is approximately 300m.
10-1-1. Connection
Up to three nonpolarized external devices can be connected. It should not run along side AC or
other high-voltage wiring. It may cause of malfunction.
* Up to 3 remote displays (LD514) can be connected. The each display (Gross weight, Net weight,
Tare weight) can display individual content according to the selection.
* These indicated above are examples for the connection of remote displays (LD557A, LD514,
M252B). Each display can select the data (Gross weight, Net weight, Tare weight) individually.
10-1-2. Auto Print Command
The F701-C gives an auto print command to any device connected by SI/F interface.
In sequence mode, the auto print command is output when the judgment signal (Go, Over, Under)
turns ON. Therefore, be aware that the auto print command is not output when no judgment is set
(Judging Times = 00). In simple comparison mode, the auto print command is output when the
complete signal turns ON. Therefore, the auto print command is not output when the setting of
Final and Over/Under comparison is comparison OFF (Weighing Function 1 in setting mode 2).
An auto print command is outputted to the external device when the accumulation command is
received by the external input/output signal or through the RS-232C, RS-485 (option), CC-Link
(option).
