3.5.3 Antenna Connection
The connection of the antennas takes place via two built-in reverse SMA plugs.
The main antenna is connected to the right connector (Main Ant.) and at the left
connector (AUX Ant.) an auxiliary antenna can be connected in addition.
The main antenna is used to transmit and receive; the auxiliary antenna is only used to
receive. The module independently selects the antenna with the better reception.
Note:
The connection of an auxiliary antenna is not mandatory. The auxiliary
antenna, however, may enhance the reception (diversity) and thus increase
the transmission rate.
Frequency:
2.4 GHz (ISM frequency band) – ETSI channel

3.5.4 Digital Inputs And Galvanic Insulated Outputs
3.5.4.1 Digital Inputs (Only INSYS WLAN serial)
The digital inputs are designed as pull-up and are on HIGH in inactive, open state. The
inputs are set through the connections to the device ground (GND). It is furthermore
possible to query the state of the inputs (
AT*I
) remote by. See also AT command set,

3.5.4.2 Galvanic Insulated Switch Outputs (Only INSYS WLAN serial)
The switch outputs are operated via AT command (
AT*Y
), which is also possible by
remote. The switch outputs are galvanic insulated relay switches.
The maximum switch voltage may not exceed 30V DC or 42V AC.
