To communicate with the Pulse Streamer, you need to know its IP address. By default, the device will attempt to acquire an IP address via DHCP. There is also a preconfigured second permanent IP address that allows direct connection to the PC, see Permanent Static IP.
# Example: # using default hostname ps = PulseStreamer('pulsestreamer') # using fallback IP ps = PulseStreamer('169.254.8.2')
Starting from the Pulse Streamer firmware v1.2, you can discover all accessible Pulse Streamers in the network and their IP addresses using
# Example # query the network for all connected Pulse Streamers devices = findPulseStreamers() # query the network for a Pulse Streamer with specific serial number devices = findPulseStreamers("00:26:32:F0:3B:1B")
Assign a static IP with the MAC address and DHCP¶
You can configure your DHCP server or router to assign a static DHCP IP to the Pulse Streamer’s MAC address. In this way, you know the IP that the Pulse Streamer will receive by DHCP. You find the MAC address of your Pulse Streamer on the bottom label of the device. It is the same as the serial number.
To verify your network configuration, open a terminal and enter
[user@host~] arp Address HWtype HWaddress Flags Mask Iface 192.168.1.108 ether 00:26:32:f0:09:30 C wlp1s0 router ether 18:83:bf:c1:1f:67 C wlp1s0
In this example, the first line is the Pulse Streamer, and the second line is the router.
Permanent static IP: 169.254.8.2¶
The Pulse Streamer is always reachable via a permanent second static IP-address 169.254.8.2 (netmask 255.255.0.0). This address allows you to establish a connection when the Pulse Streamer is connected directly to your computer with an Ethernet cable. This shall work out-of-the-box on both Windows and Linux (requires avahi/zeroconf). In some cases, however, you may need to reboot your computer to detect the Pulse Streamer, if there has been a DHCP-connection before.
Modify the network settings¶
By default, the Pulse Streamer 8/2 will attempt to acquire an IP address via DHCP. If you want to assign a specific IP address to your device, you can disable DHCP and configure a static IP instead. We recommend using our Pulse Streamer Application (Windows only) to modify the Pulse Streamer 8/2 network configuration. The graphical user interface will guide you through the network configuration. You can enable/disable DHCP and set a specific IP address, the netmask, and the default gateway for a static IP configuration. You can test the new network settings before deciding to apply the configuration permanently in a second step.

Configuring the network settings:
On the startup-screen with the listed devices, click the button
Edit network configurationbehind the IP-address field.
Choose your settings in the pop-up window.
Test Settingsto check if the device is reachable via the new settings (power-cycling resets the changes).
Applyto set the configuration permanent.
Alternatively, you can configure the device’s network settings via our client software interfaces. For more information, see Modify the network configuration section.
