ment is installed.
2.1.4 Connecting the WLAN antenna
The Teldat H1 RAIL has N connectors to connect up to 2 WLAN (Wi-Fi) antennas in the models that have this inter-
face.
The device does not have internal antennas, so the installation of antennas in the Teldat H1 RAIL routers is essen-
tial in order to improve the quality of the signal received and transmitted by the Wireless LAN module.
The cable used to connect the antennas must be a cable which is valid for RF signal communications of up to 2.4
GHz (5.7 GHz for 802.11a) frequencies and a 50 Ohm impedance. Please note that the quality and the length of the
antenna cable (loss) may have an impact on the quality of the RF signals transmitted and received and, con-
sequently, on device coverage and the speed at which the data is exchanged.
For the Wireless WAN interface to be operative, the device must have the corresponding software license incorpor-
ated.
The following image shows you where to find the antenna connectors for the WLAN modules.

2.1.5 Connecting the GPS antenna
The Teldat H1 RAIL router has an FME connector to connect an active GPS antenna in the models equipped with
this interface.
The device does not have internal antennas, so the installation of an active 3.3V external antenna in the Teldat H1
RAIL routers is essential in order to improve the quality of the signal received by the GPS module.
The cable used to connect the antennas must be a cable which is valid for RF signal communications of up to 1.5
GHz frequencies and a 50 Ohm impedance. Please note that the quality and the length of the antenna cable (loss)
may have an impact on the quality of the RF signals received and, consequently, the accuracy and speed at which
the position is obtained.

2.1.6 Configuration connection
2.1.6.1 Configuring through the local console (AUX connector)
The Teldat H1 RAIL router has a DB9 female connector on the front panel known as “ AUX.”, which provides access
to the device’s local console or may operate as an asynchronous serial port. The behavior or functionality of this in-
terface must be previously configured. By default, this interface is configured in local console mode. This section fo-
cuses on the connection for the local console mode.
To configure this, you must connect the “ AUX.” port to an asynchronous terminal (or to a PC with terminal emula-
tion).
