3.2 Communication and Configuration
3.2.1 Communication parameters
Communication between the host and terminals is performed under an asynchronous mode. The baud rate is
programmable, enabling rates from 1200 to 19200 bps.
3.2.2 Multiple terminal configurations
RS-485 communication enables you to connect up to 32 terminals to a single COM port and/or to extend the cabling
distance to up to 1,000 meters (3,280 feet) using 9600 baud via an RS-485 multi-drop line. RS-485 communication uses
three wires as opposed to RS-422 communication, which uses four wires.
3.2.3 Point to point configuration
A single SY-765 terminal, equipped with RS-232 communications, can be connected directly to an asynchronous
RS-232 port. If RS-232 communication is used, only one terminal may be connected to each COM port and
cabling distances should not exceed 50 ft.
3.2.5 Network connections
The terminal can be connected to one of the following communication networks:
Ethernet (optional card) - For this type of communication, an IP address is defined for every SY-765 terminal,
enabling communication with each terminal in any 10/100 Ethernet network.
Wi-Fi (optional card) - For this type of communication an SSID is specified to authorize the connection and an
IP address is defined for every SY-765 terminal, enabling communication with each terminal in TCP/IP protocol.
