Descrizione

OUTLINE

The converter is compatible with RS-232, RS-485 standard, the ability to RS-232 signals into single-ended RS-485 signal balanced differential built fast transient voltage suppression protection TVS; no external power supply, internal unique “RS-232 charge pump” drive the entire circuit; a circuit with zero delay automatic conversion transceiver means anti-collision of I / O circuit automatic control data flow direction, thus ensuring in RS-232 mode programs written without changing , it can be safe to run in RS-485 mode, absolutely sure fit existing operating software and interface hardware.

APPLICATION

– PC, terminal equipment
– Industrial control, digital instrument collection
– Multiple serial devices to serial interface devices

PERFORMANCEe PARAMETERS

– Interface Features: interface is compatible with EIA / TIA RS-232C, RS485 standard.
– Electrical Interface: RS-232 terminal DB9 female connector, RS-485 side DB9 male connector with terminal.
– Working mode: asynchronous half-duplex differential transmission.
– Transmission media: twisted pair (diameter greater than or equal to 0.5MM) or shielded cable.
– Transfer rate: 300-115.2KBPS.
– Dimensions: 64 mm * 33 mm * 17mm.
– Use of the environment: -20 Degree Celsius to 70 Degree Celsius, relative humidity of 5% to 95%.
– Transmission distance: less than 1,200 meters (RS-485 terminal) 15 meters (RS-232 terminal) within.
– Protection level: RS-485 interface to 600W per line lightning surge protection.
– Two kinds of communication: point to point / multipoint and half duplex two-wire / two-wire half duplex.

NOTE

– In order to prevent reflection and interference signals, to be connected to a terminal at the line matching resistor (120 ohms parameter 1 / 4W), as the case may be.
