abling the connection of external modems or an asynchronous PPP WAN.
Another interesting feature of this port is the possibility of using it as a GPS data source, in NMEA sentences
(GPS-DATA).
This interface only operates in accordance with the V24 norm. Since it only has data signals (not control signals), it
cannot control hardware flow. It does, however, allow for software flow control (XON/XOFF).
You cannot configure parity in MARK and SPACE modes.
To do this, connect the AUX port to an asynchronous terminal (or to a PC with terminal emulation).
To use the port as a router configuration port, please see Section

3.6.6 Connecting to a WWAN antenna (cell connectors)
The Teldat H2 Automotive routers can have three or five connectors in order to connect the WWAN antennas, de-
pending on the number of WWAN modules installed in the device.
To assemble and remove the antennas, simply screw/unscrew them into/from the connectors labeled R1, R2 and R3
(future use) for Module 2, or C1 and C2 for Module 1.
Installing antennas in the Teldat H2 Automotive is essential to improve the quality of the signal received and trans-
mitted by the Wireless WAN module (GPRS, UMTS, HSDPA, HSUPA, HSPA+, LTE, etc.).
Note
- For optimum performance, always install the WWAN antennas.
- The
Wireless WAN
interface is only operative if you have installed the corresponding software license.
Some cellular telephony technologies use antenna diversity to improve the quality of the received signal (HSUPA,
HSPA+, LTE, CDMA EV-DO, etc.). Therefore, the Teldat H2 Automotive incorporates five connectors for each mod-
ule installed.
• The MAIN antenna for each module (R1, C1) is installed in the ANT connector.
• The auxiliary or DIVERSITY antenna for each module (R2 and C2) is installed in the ANT connector too.
Module 2
Module 1
R1 -> MAIN Antenna.
C1 -> MAIN Antenna.
R2 -> DIVERSITY Antenna.
C2 -> DIVERSITY Antenna.
R3 -> Reserved for future use.
The following image shows where to find the antenna connectors for the cellular modules.
