ANTENNA CONNECTORS

The QLS antenna connectors are located at the bottom part of the front panel. Besides the GNSS connector each radio interface connector is labeled from A1 to A6. Their functionalities depend on the CyBox model (see 3.4.1 Assignment Front Panel Labelling – Software).

When connecting an antenna to the QLS connector, make sure that you hear a ‘click’ sound confirming proper mounting. To remove an antenna, it has to be gently pulled from the basis of the connector with one hand, while the other hand is holding the antenna. Alternatively, a screwdriver can be used as a lever arm at the basis of the antenna to facilitate the removal, as illustrated below.

POWER SUPPLY

POWER INPUT

The CyBox AP 2 and CyBox LTE 2 can be powered by a DC power source connected to the internal power supply and I/O connector, shown in Table 1 . The nominal input voltage can vary between 24 V and 110 VDC.

POWER OVER ETHERNET (POE+)

The CyBox AP 2 and CyBox LTE 2 are designed to be supplied via the Ethernet uplink, as class 4 powered device, according to IEEE 802.3at. In this case the supply voltage is  provided remotely over the injector. Important: The Power- over-Ethernet option is applicable on certain devices only.

M12 SERVICE INTERFACE (USB AND SERIAL PORT)

The CyBox AP 2 and CyBox LTE 2 are equipped with a USB and serial port. The USB port can be used to attach a memory device to update the firmware or to configure the device.

Note that the USB port is a dedicated maintenance port. It is not designed to be used while the device is in operation inside rolling stock equipment.
Table 3 shows the pin assignment of the service connector.

| PIN| SIGNAL NAME| DESCRIPTION
---|---|---|---
| 1| USB-VCC| USB positive power supply voltage
2| USB-D-| USB negative data line
3| USB-D+| USB positive data line
4| USB-GND| USB negative power supply voltage
5| n.c.| Not connected
6| RS323-TX| Console port transmit data
7| RS232-RX| Console port receive data
8| RS232-GND| Console port ground

•  The ports and LEDs “LAN 1” and “LAN 2” correspond respectively to the interfaces “eth0” and “eth1”
• The LEDs “Module 1” and “Module 2” refer to WLAN and/or LTE modules
• WLAN modules are called “radio” within the software
• LTE modules are called “modem” within the software
• The purpose of the antennas depends on the modules inserted in your Cybox model

RESET SWITCH

The CyBox AP 2 and CyBox LTE 2 is equipped with a hidden reset switch behind the front panel, close to the top-right corner. The button is accessible with a straightened paper clip pushed through the little hole on the front panel. The effect of pressing the reset switch depends on the duration of its activation, as indicated in Table 10 below. The timing behaviour is only valid if the device has completely booted (after approx. 1 min). While the device is booting or executing U-Boot, pushing the button will always reset the device.

The following table describes the functions of the reset switch.

Table 10 Reset Switch Behavior

SIM CARDS

The CyBox LTE 2 provides 4 SIM slots per LTE modem. Only one slot per modem can be active at any time. To install SIM cards, the back panel of the CyBox LTE 2 has to be removed using a suitable Torx 10 screwdrivers. After installing the SIM cards, the back panel must be closed and the screws tightened to a maximum torque of 0.55 Nm. The indexing of SIM slots is software dependent and can be selected via an SNMP command or using the web interface.

Note:
Switching between SIM slots takes about 30 seconds, slot 1 being preselected at power-up. If you plan to use only one SIM card for a given LTE modem, it is advisable to use slot 1 to avoid slot switching delay during the boot phase.

The drawing in Figure 4 shows the SIM slot assignment per modem.

Figure 4 SIM Slot Assignment per Modem of the CyBox LTE 2

Important: Do not change the SIM cards when the device is powered since there is a danger of touching the main voltage when the device is open.

MOUNTING

When mounting the CyBox AP 2 and CyBox LTE 2, please take into account the following aspects:

• Do not install the device close to any sources of heat, such as radiators or heat registers.
• Keep the device away from any liquids and avoid exposure to dripping or splashing. The protection class of the housing is IP40.
• Keep a free space of at least 150 mm around the housing to ensure adequate heat dissipation capabilities.
• For optimal heat dissipation, the connectors should face down.
• The housing provides four mounting cutouts to install the device in a horizontal or vertical orientation on a flat and stable surface.
• For fixation use M6 screws of sufficient length with additional M6 washers. The drawing in Figure 5 shows the outer dimensions of the housing, including the position of the mounting cutouts.

Figure 5 Dimensions of the CyBox AP 2 and CyBox LTE 2 Housing

CONNECTING AN EARTHING CABLE

A M6 earthing stud on the front panel of the device (also refer to Figure 3) for protective earth connection is essential for device security. Carry out the following steps to connect an earthing cable:

• Use an earthing cable with a cross-section of at least 2.5 mm² and a wire end sleeve with an eyelet suitable for a 6 mm threaded bolt.
• Mount the earth cable as shown in Figure 6.
• Fasten the cable by tightening the nut to the required torque (recommended according to EN609471 are 3 Nm).

Figure 6 Earth Cable Mounting on Earth Stud

ELECTRICAL CONNECTION

1. Make sure the device is properly grounded.
2. Establish a connection to the network by plugging an M12 patch cable into one of the front panel M12 connectors. Each LAN port may be used if the access point is supplied by a local power supply through the power supply connector. When using PoE+, the connector labelled LAN1 must be used.
3. Connect the desired number of antennas to the device. Each radio/modem can use up to four antennas for maximal performance.
4. In the case of using a local power supply, the appropriate wiring (see Table 1 ) must be established to connect the power line to the device.
5. Make sure that the voltage of the power supply conforms to the voltage on the type plate.
6. Ensure that the power supply is grounded correctly and that the power cable is intact and undamaged. Do not switch on the system if there are damages to the power cable or plug.
7. Use power cables which are approved for the power supply in your country. 8. The device itself has no on/off switched, it starts as soon as it is supplied with power.
