FAQ's - Frequently asked questions for the AnaGate series

Here is a list of frequently asked questions.

Questions

Problem: No LAN connection

If no LAN connection is registered (the link LED next to the RJ45 socket does not light up), please check the wiring between the AnaGate I2C and the hub or switch.You need to use a crossover cable when connecting the device directly to a PC.

Please check that the AnaGate device is connected to the power supply.

Problem: No TCP/IP connection

If you cannot set up a TCP/IP connection to the AnaGate, please proceed as follows:

  1. Check for an existing LAN connection.
  2. Check if you can address the device with a ping.
    To do this, launch the MS Windows command prompt and enter the command “ping a.b.c.d” (replace a.b.c.d with the IP address of the AnaGate). If there is no response, check whether the RX LED next to the RJ45 socket lights up while executing the ping command.
    If you still cannot address the device, perform a factory reset, configure your PC using the IP address 192.168.1.253/255.255.255.0, and repeat the aforementioned procedure using the IP address 192.168.1.254.
  3. Check whether you can open a TCP connection at port 5000.
    To do this, launch the MS Windows command prompt and enter the command “telnet a.b.c.d 5000” (replace a.b.c.d with the IP address of the AnaGate). If you do not get a connection immediately, check whether a firewall or packet filter is installed between your PC and the AnaGate.

Problem: Using a firewall

When working with a firewall, the a TCP port has to be opened for communication with the AnaGate device:

  • AnaGate I2C: Port 5000
  • AnaGate SPI: Port 5002
  • AnaGate CAN, CAN uno: Port 5001
  • AnaGate CAN duo, F2, X2, FX2 : Port 5001, 5101
  • AnaGate CAN quattro, F4, X4, FX4 : Port 5001, 5101, 5201, 5301
  • AnaGate Renesas: Port 5008
  • AnaGate CAN F8, X8, FX8 : Port 5001, 5101, 5201, 5301, 5401, 5501, 5701
  • AnaGate UP, UPP: Port 5000, 5002, 3333, 4444, 20, 21
  • AnaGate UPR: Port 5000, 5002, 5008, 3333, 4444, 20, 21
  • AnaGate UP 2.0: Port 5000, 5002, 3333, 4444

Problem: No network connection after changing the network address

After changing the network address of the AnaGate on the web interface, the device is not longer reachable. The Internet browser displays only an empty web page without any error messages.

Please check if your anti-virus software has blocked the new network address. After changing the network address you are redirected to the new network address in the browser. Such actions are considered suspicious by some antivirus software, so they block the new web page, sometimes even without notification of the user.

Problem: Connection problems using multiple devices

If multiple devices with identical IP addresses are used in a local area network at the same time, the connections to the devices are not stable. It is therefore necessary to use different IP addresses on all devices.

This problem can also occur, if devices with identical IP addresses are not simultaneously connected to the network, but connected one after the other in short time intervals. For example, this can occur, if new devices, which have the default IP address 192.168.1.254, are configured from a single PC.

The Address Resolution Protocol (ARP) is used in IPv4 networks to determine the MAC address of a given IP address. This information is stored in the ARP cache. If wrong or no longer up-to-date entries are present, the affected hosts cannot be reached anymore. An entry in the ARP cache is deleted, if it is not used anymore after a short period of time. The time interval is set by the operating system. The ARP cache can be displayed and modified with the arp command on Windows and Linux.

C:\>arp -a

Interface: 10.1.2.50 --- 0x2
 Internet Address    Physical Address     Type
 192.168.1.254       00-50-c2-3c-b0-df    dynamic

The command arp -d can be used to empty the ARP cache.

AnaGate I2C problem: No I2C communication

If communication with your AnaGate I2C device fails, please proceed as follows:

  1. Check that the I2C device is connected to the power supply.
  2. Check that no other devices/µC are active on the I2C bus.
  3. Ensure that the SDA and SCL circuits are provided with an adequate pull-up resistance (e.g. 4.7 kOhm) to the voltage supply (3.3 V resp. 5 V).
  4. Ensure that no other electrical components can interfere with communication on the I2C bus between the AnaGate I2C and the I2C device.
  5. Ensure that the chip-enable address of the I2C device and the software are identical.

AnaGate I2C problem: What is the sequence of the GND / SCL and SDA contacts when using an external power supply?

To avoid potential damage to the AnaGate I2C, the GND pin MUST be connected to the application board first. Only then can the SCL/SDA pins be allowed to make contact with the application board.

Problem AnaGate SPI: Connecting to a KMA200

Accessing a KMA200 of Phillips with th AnaGate SPI is easily possible via a special adaptor.

Following you wil find a guide to  program the KMA200 device.
