Operating instructions

BAL SX302 ETH EN 3.1 9
Parameterization The parameterization of the unit is done by means of a menu in the menu display
(see chapter 4).
Ethernet interface The Ethernet interface serves for activation of the devices (see chapter 4.) It is a
standard-RJ45 socket and has the following specifications:
Data rate: 10/100 Mbps, Automatic detection
Galvanic separation: 1,5 kV
Supported protocols: ICMP, ARP, IP, TCP, UDP, DHCP, Telnet and HTTP
Operation modes: TCP Server, TCP Client and UDP
The units are set-up as TCP server by default. The data
is transmitted to port 8000 via a socket connection
(factory settings). Other ports between 2000 and 9999
can be set via the menu (see chapter 4).
Configuration: The basic configuration can be set up without external
aids via the menu (see chapter 4). Further settings can
be done via Web Browser or Telnet console (see
chapter 5).
The Telnet and HTTP protocols are used exclusively for configuration, not for data
transmission.
Function inputs The function inputs allow, independently of commands via the Ethernet interface, a
reduction the brightness and the flashing of the display (see chapter 3). It is
located on the screw type terminal of the control computer.
The function inputs are PLC-compatible and are designed for the following signal
voltages:
Signal voltage: L = -3.5...+5 V (open input = L)
H = +18...30 V (active H), M = reference potential
Auxiliary voltage The units supply terminal P with an auxiliary voltage galvanically isolated from the
operating voltage, which can serve as H signal (24 V ± 25%, max. 50 mA, M =
reference potential).
Menu display The menu display represents a menu for unit parameterization (
see chapter 4).
During normal operation OnnE appears in the menu display as soon as data
arrive at the Ethernet interface.
Menu buttons The menu can be operated by means of the menu buttons (see chapter 4).
Switching output The devices dispose of a switching output (relay) with potential-free change-over
contact (NC, NO, CO).
