This interface allows asynchronous serial devices (those that do not require hardware control signals) to connect.
This way, external modems or an asynchronous PPP WAN may be connected.
This interface operates in compliance with the V.24 norm and only uses data signals (not control signals). While you
cannot carry out hardware flow control here, you can execute flow control through software (XON/XOFF).
You cannot configure parity in MARCA and ESPACIO modes.
For configuration purposes, connect the Conf. port to an asynchronous terminal (or to a PC with terminal emulation).
To connect to this port, use the RJ45 connector cable together with the RJ45 female-DB9 female adaptor (both
provided with the router).

2.1.3 Connecting the WWAN antenna
The Teldat H/L has one or two connectors for WWAN antennas. To assemble/remove the antennas, simply screw/
unscrew them into/from the connectors labeled WWAN (located on the rear of the router).
Some Teldat H/L modules may not incorporate the Wireless Wan module. These routers do not have RF connectors
for WWAN.
Installing these antennas on the Teldat H/L is essential to improve the quality of the signal received and transmitted
by the Wireless WAN module (GPRS, UMTS, HSDPA, HSUPA, etc.).
Note
• For optimum performance, always install the WWAN antenna(s).
• The Wireless WAN interface is only operative if you have installed the corresponding software li-
cense.
Some cellular telephony technologies use antenna diversity to improve the quality of the received signal (HSUPA,
CDMA EV-DO, etc.). Therefore, some Teldat H/L routers incorporate two WWAN connectors.
The following image shows you where the antenna connector is, on devices that do not use antenna diversity
(DIVERSITY).
