Wirnet™ iBTS: Connect to the gateway

Any questions on the product or accessories: please read the Installation and maintenance manual.

To connect to the Wirnet™ iBTS gateway, the following accessories are needed:

Ethernet cable: To access/use the gateway.

PoE injector or DC power supply (11V to 56V): To power the gateway.

Optional: Wirma2 debug tool: Debug probe to access to linux console, with USB wire (A type < — > B type): to connect it to the PC.

Note for PoE

PoE class is depending on the configuration of the Wirnet™ iBTS as power consumption becomes higher accordingly to the number and the type of RF modem (consult Kerlink to choose correct PoE device).

Power supply the gateway

For the following points, detailed instructions are available in the Wirnet™ iBTS “Installation and Maintenance manual” of the iBTS setup page.
There are two ways to power on the Wirnet™ iBTS:

Connect the PoE output connector to the LAN port located on the bottom side of the CPU module. The RJ45 connector can be inserted directly to the gateway using a specific cable gland.

Connect the DC power supply to the Aux Power connector identified by the 11-56V indication, respect the +/- indications.

Plug a RJ45 cable from the network in the DATA IN socket of PoE. PoE injector LED orange is ON.
Plug the PoE (DATAOUT socket) to the Wirnet™ iBTS using a RJ45 cable. PoE injector LED green is ON.
Check the following status once the gateway is well powered :
- green LED DEBUG socket is ON.
- orange LED DEBUG socket blinks every 5 seconds.

Connect through the network

Please see the connection, login and credentials page for more information on how to connect to your iBTS.

Local connection (LOCAL Ethernet)

You can connect a PC directly to the iBTS with a cable to its LOCAL Ethernet port.

In nominal case, after few seconds, your PC will obtain an IP address and you will be able to start a SSH client or HTTP connection on gateway IP 192.168.120.1.

In particular case you are using a DHCP server on your computer, gateway will directly obtain an IP address. A connection can then be done on this IP address.

See here for more information about SSH/HTTP connection details.

Debug probe

To use the debug probe, it is necessary to download FTDI drivers on this website.

Windows installation

Download ftdi drivers.
Install the drivers.

Linux installation

On Linux, everything should work out of the box. The serial port will be located in /dev/ttyUSB*.

If it didn't work

It is necessary to tell the Kernel to load the proper FTDI driver when the debug probe is plugged.

To do so, list the USB devices and see the product and vendor IDs:

$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 039: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
Bus 001 Device 005: ID 0461:0010 Primax Electronics, Ltd HP PR1101U / Primax PMX-KPR1101U Keyboard
Bus 001 Device 045: ID 18d1:4ee7 Google Inc. 
Bus 001 Device 003: ID 0424:2512 Standard Microsystems Corp. USB 2.0 Hub
Bus 001 Device 002: ID 045e:07fd Microsoft Corp. Nano Transceiver 1.1

Here the debug probe is located on the 1st bus, device 039. The device should be automatically recognized. To check the FTDI kernel module is loaded, the following command can be used:

$ lsmod | grep ftdi
ftdi_sio               53248  1
usbserial              53248  3 ftdi_sio

Next, create a udev rule matching this, and place it in a file called /etc/udev/rules.d/99-usbftdi.rules (for example):

# Added on xx/yy/zzzz for Kerlink debug probe by foobar
# For FTDI FT232 & FT245 USB devices with Vendor ID = 0x0403, Product ID = 0x6001
ATTR{idProduct}=="6001", ATTR{idVendor}=="0403", RUN+="/sbin/modprobe ftdi_sio product=0x6001 vendor=0x0403"

Be sure to replace the product/vendor IDs if they need to be changed. This will have the FTDI Kernel module loaded when the debug probe is plugged.

Next, reload the device tree: udevadm control –reload-rules && udevadm trigger (run as root).

If necessary, the device in /dev could be renamed. To do so, add , SYMLINK+=“debug_probe” to the udev rule.

Here's the result:

$ ls -l /dev/debug_probe
lrwxrwxrwx 1 root root 15 04-06 16:05 /dev/debug_probe -> ttyUSB0

Using the debug probe

Connect the debug tool (WIRMA2_DEBUG_TOOL) with a standard ethernet cable to the “DEBUG” port and with an USB cable to the PC.
Open an hyperterminal like tool on the com port with the following standard parameters:

baudrate : 115200
data length : 8
parity : none
stop bit : 1
flow control : none

After getting prompt, enter login/password (“root / pdmk-$serialno”). pdmk-$serialno is the default password on the gateway. See here for more information. In case of failure, request password to Kerlink support team.
