Connections
X2 (10/100 Base-T)
The local network is connected to the local applications at the 10/100 Base-T
connection, e.g. a programmable controller, a machine with an Ethernet interface
for remote monitoring, or a notebook or desktop PC.
To set up the SINAUT MD741-1, connect the Admin PC with Web browser here.
The interface supports autonegotiation. It is thus detected automatically whether a
transmission speed of 10 Mbit/s or 100 Mbit/s is used on the Ethernet.
A connecting cable with a RJ45 plug must be used. It can be a cross-over cable or
a patch cable.
X1 (USB; Service)
In the SINAUT MD741-1 this interface has no function and is reserved for later
applications. Do not connect any devices here. Doing so could interfere with the
SINAUT MD741-1's operation.
SMA antenna jack
The SINAUT MD741-1 has an antenna jack of the type SMA for connecting the
antenna.
The antenna that is used should have an impedance of about 50 ohms. It must be
matched for GSM 900MHz and DCS 1800MHz or GSM 850 MHz and PCS 1900
MHz, depending on which frequency bands your GSM network operator uses. In
Europe and China GSM 900MHz and DCS 1800MHz are used, in the USA GSM
850 MHz and PCS 1900 MHz are used. Obtain this information from your network
operator.
The match (VSWR) of the antenna must be 1:2.5 or better.
Caution
Use only antennas from the accessories line for the SINAUT MD741-1. Other
antennas could interfere with product characteristics or even lead to defects.
When installing the antenna, a sufficiently good signal quality must be ensured
(CSQ > 11). Use the indicator lamps of the SINAUT MD741-1 which show the
signal quality. Make sure that there are no large metal objects (e.g. reinforced
concrete) close to the antenna.
Observe the installation and user instructions for the antenna being used.
