SI/F Connection
(RS-485 or SI/F specified at the time of order: SIF)
This is a two-wire serial interface for connecting
printers, external display units and so on made by
UNIPULSE
Up to three external devices can be connected with no polarity. Use two-core parallel cables, captire
cables (electric wires with thick coating for construction) and so on for wires. In case two-core
parallel cables and captire cables are used, transmission distance is approx. 30m. In case two-core
shield twisted pair wires are used, transmission distance is approx. 300m. Do not parallel AC lines
and high-pressure lines. This causes malfunction.
