There may be several reasons why you would like to know the MAC address of a Suprema device:
You do not have a DHCP server and need to give IP address based on a MAC address
You do not know the IP of your device and are having difficulty searching it through BioStar’s search function
You are using static IP but are unsure if you have already allocated the IP address to another device.
Methods to Check the MAC Address
1. Finding IP and MAC addresses of all devices on the local network:
Type ‘arp –a’ on a command prompt
2. Finding a device’s MAC address based on IP address:
Type ‘arp –a [ip address] on a command prompt
Checking Device IP Address Based on the Device ID
If you would like to find the device’s IP based on the MAC address you can follow the steps below.
1. Check your device ID written on the device label on the back of the device.
2. Change the device ID into hexadecimal numbers. One option is to use Windows’ Calculator.
3. Open Windows Calculator and press alt + 3 to change to the programmer’s calculator.
4. Select Dec and input the device ID.
5. Click Hex. Result is 20471BC5. This is going to be the latter half of the MAC address.
6. Check the MAC address chart below to see what the first half of the MAC address will be.
7. My device is an A2, so the MAC address will start with 00-17-FC-47-XX-XX.
8. Hence my MAC should be 00-17-FC-47-1B-C5.
9. Open a command prompt and type arp –a.
10. Search for the device’s MAC address on the list.
11. My device IP is 192.168.16.104.
Suprema Device MAC Address Chart
Suprema devices have the same fixed hexadecimal digit for the first six digits.
The two digits after 00-17-FC are different based on the device model. Please refer to the chart below.
How to Find a Device's IP Address with Wireshark
You can use this option if
Your device does not have a LCD and it’s IP has been configured to a different subnet and you cannot figure it out with arp –a command on command prompt.
Your device has a LCD but you don’t know the admin account and cannot access the menu. Additionally the device has a unknown subnet configured and you can’t search it with arp –a on command prompt.
You can use Wireshark to figure out the IP address of a device with a different subnet.
You can download Wireshark from the following link
Follow the procedure below.
1. Install Wireshark.
2. Find the MAC address of the device with the device ID by using the chart above and a calculator.
3. Connect your device with your PC directly with an Ethernet cable.
4. I have a BioStation 2-OMPW and the ID is 546832586.
5. According to the chart above the MAC should start with 00-17-FC-98.
6. When I change ID from dec to hex on the calculator the result is 209800CA.
7. My device’s MAC address is 00-17-FC-98-00-CA.
8. Run Wireshark.
9. Go to Capture > Options…
10. Select your network card interface and click start.
11. Put a filter with the MAC address with the format shown below.
eth.addr == xx-xx-xx-xx-xx-xx
12. Click on the arrow to start the filter.
13. Power off and power on the device.
14. Now you will only see packets that are coming from your device. Wait for 5 minutes if it doesn't appear.
15. Look for the arp request.
16. The device’s ARP request is ‘Who has 10.111.111.1? Tell 10.111.111.111
The 10.111.111.1 is the gateway set on the device
10.111.111.111 is the device IP
17. Connect your device directly to a test PC with BioStar 1 / 2 Server installed using a ethernet cable.
18. Set the test PC IP into the same subnet range of your device.
19. Search and add the device in BioStar and change the device IP.
