18-1. SI/F 2-wire Serial Interface

This is a serial interface specifically designed to connect with external equipment such as
a printer, large display, etc., manufactured by us. This interface is a 2-wire type, which
requires only simple and low-priced work. 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
Connections with external equipment manufactured by us are non-polar, and up to three
units can be connected in parallel. Do not make these parallel with AC lines and high-
voltage lines .It may cause of malfunction.
Example 1: In the Hysteresis / Wave & Displace mode
Up to three small displays can be connected. Descriptions to be displayed can be selected
independently.
Example 2:
The above example shows connection of a large display, small display and printer. Data
to be displayed (printed) can be selected independently.
