  o Reset config to factory defaults
  o Enable DHCP (in case it was set to an incorrect static IP)

• Hold button for 12 seconds:
  o Reset config to factory defaults
  o Enable DHCP
  o Rollback firmware

After each period, the LEDs will blink orange, meaning both status and power red/green go on and then off. As an indicator that you have held the button down long enough.
If you hold it for 3 seconds, the LEDs will blink. If you continue to hold it, it will blink again at 6 seconds, and so on.
3.2.5 External Antenna
The external antenna connector is a 50-ohm FAKRA jack. For FCC and Industry Canada environments approved external antennas are:

• Clairvoyant Technology’s 7.5dBiC right-hand circularly polarized patch antenna with a maximum linear gain of 6.15dBi. A minimum of 0.15dB cable loss is required for use of this antenna. This antenna is IP67 environmentally rated.
• Clairvoyant Technology’s 9dBiC right-hand circularly polarized patch antenna with a maximum linear gain of 9dBi. This antenna is IP67 environmentally rated. This antenna requires a minimum of 6dB cable loss if the reader is set to transmit full power. This antenna is for Professional Installation Option Only; see section 4.5.

3.3 GROUNDING
FIGURE 7 above shows the location of the “GND HOLE” for system grounding. The ground slug is M4.

INITIAL READER CONFIGURATION

4.1 ETHERNET
The reader defaults to using DHCP and will take on the IP address provided by the DHCP server. If there
is no DHCP server it will obtain an IP address by negotiating with other network devices on the nonDHCP network. Typically, it will get an IP address in the 169.254.. space.
The reader can also be configured to obtain a static IP address as shown in Section 4.1.2.
4.1.1 Discover S1 Readers
To “discover” the reader’s IP address. You can use a Bonjour client like “avahi” or you can use the
Clairvoyant Host Software tool. The available ports on the reader are described in the table in the section
4.1.3.
4.1.2 Configure IP Address
The Clairvoyant Host Software tool can be used to configure the IP address of the reader. This can be done via the “Reader Connection Dialog” after pressing “Discover”. It can also be performed using the “Configure→IP Address” menu after connecting to a specific S1 reader.
4.1.2.1 Reader Connection Dialog
Changing the IP address via the “Reader Connection Dialog” can be done by clicking on the “Details” button after selecting the desired S1 reader to configure.

Pressing on “Details” presents the “Details Dialog”. Press IP Address from the “Details Dialog” to bring up the “Configure IP Address” dialog.

4.1.2.2 Configure Menu
Once the Clairvoyant Host Software tool is connected to an S1 reader, the “Configure” menu can be used to bring up the “Configure IP Address” dialog.

4.1.2.3 Configure IP Address Dialog
The ”Configure IP Address” dialog allows for a “DHCP” or “Static” configuration. If “Static” is selected, all three IP address values must be specified (IP Address, Gateway, Netmask).

After pressing the “OK” button, the IP address configuration will be sent to the S1 reader.
Note, if “Static” is selected and the IP address / Gateway / Netmask is not configured properly for the network in which the S1 reader resides, the S1 reader will lose communication over the network.
In the case where an S1 reader is improperly configured and cannot be communicated with over TCP, the “Reader Connection Dialog” can be used to reconfigure the IP  address properly if the S1 reader is available on the same subnet as the PC where the Clairvoyant Host Software tool is running. This tool utilizes multicast to perform this function and improperly configured IP addresses can be fixed.
4.1.3 IP Interfaces

239.192.7.2)
NTP| Network Time Protocol Client
Bonjour| Discovery protocol

4.2 DIGITAL I/O
There are two digital inputs and two digital outputs that can be used to either trigger the reader to enter or leave active mode or to perform other user operations. Please see the RAIN Communication Interface (RCI) documentation on the Clairvoyant website for more information.
The digital I/O can be monitored, and the output can be changed via the Clairvoyant Host Software tool at the top frame of the GUI on the right-hand side:

A dark shaded circle means the status of the Input/Output is “high” and “low” otherwise. To change the state of the Output, please double-click on the circle corresponding to the output that needs to be changed.
4.3 ANTENNAS
The antennas can be configured via the RAIN Communication Interface (RCI). Please see the RCI documentation for more information.
The antennas can be configured with the Clairvoyant Host Software tool via the “Configure” and then the “Antennas” menu.

4.5 PROFESSIONAL INSTALLATION
For installations requiring the S1 to conduct higher transmit power than 1 watt and/or require an antenna with a maximum linear gain higher than 6dB must use the S1’s High-Power option. The High-Power option provides a professional installation configuration allowing the entry of antenna gains and cable losses. With this option, the reader will be capable of conducting more than 1 watt – as high as 33dBm can be conducted out of the S1 antenna ports to compensate for cable losses and antenna gains to
achieve the maximum FCC part 15 and Industry Canada RSS-247 radiated level of 36dBm EIRP.
The S1 reader is limited to a 33dBm output maximum through both hardware and software mechanisms.
The reader’s output power is always limited to a maximum of 33dBm, regardless of how much cable loss or antenna gain is specified by the professional installer.
If a professional installation is required, please add the Professional Installation License to the order at the time of purchase, or the feature can be added later via field upgrade.
