Connector
• Panel-mounted device: connected to mains via plug-in screw terminals with reverse
polarity protection
• Desktop version (option): connected to mains via IEC connector
Overvoltage protection
To avoid high-energy transients on long signal cables, connect a suitable surge arrester
upstream (e.g. E+H HAW562) in series upstream.
Connection data interface,
communication
USB ports (standard):
1 x USB port type A (host)
A USB 2.0 port is available on a shielded USB A socket at the front of the device. A USB
stick, for example, can be connected to this interface as a storage medium. An external
keyboard or USB hub may also be connected.
1 x USB port type B (function)
A USB 2.0 port is available on a shielded USB B socket at the front of the device. This can
be used to connect the device for communication with a laptop, for example.
Ethernet interface (standard):
Ethernet interface on back, 10/100 Base-T, plug type RJ45. The Ethernet interface can be
used to integrate the device via a hub or switch into a PC network (TCP/ IP Ethernet). A
standard patch cable (e.g. CAT5E) can be used for the connection. Using DHCP, the device
can be fully integrated into an existing network without the need for additional
configuration. The device can be accessed from every PC in the network. Normally only the
automatic assignment of the IP address must be configured at the client. When the device
is started, it can automatically retrieve the IP address, subnet mask and gateway from a
DHCP server. If a DHCP is not used, these settings must be made directly in the device
(depends on the network to which the device is to be connected). Two Ethernet function
LEDs are located on the rear of the device.
The following functions are implemented:
• Data communication with PC software (analysis software, configuration software, OPC
server)
• Web server
• WebDAV (Web-based Distributed Authoring and Versioning) is an open standard for
the provisioning of files via the HTTP protocol. The data saved on the device's SD card
can be read out using a PC. A web browser or dedicated WebDAV client can be selected
as network drive on the PC for this purpose.
Serial RS232/RS485 interface (option):
A combined RS232/RS485 connection is available on a shielded SUB D9 socket at the rear
of the device. This can be used for data transfer and to connect a modem. For
communication via modem, we recommend an industrial modem with a watchdog
function.
• The following baud rates are supported: 9600, 19200, 38400, 57600, 115200
• Max. cable length with a shielded cable: 2 m (6.6 ft) (RS232), or 1000 m (3281 ft)
(RS485)
Only one interface can be used at any one time (RS232 or RS485).
