1 Overview
The LinUDP V2 protocol is an easy way for communication with a LinMot servo drive over Ethernet. There
are no checks done to make sure if the messages have reached their destination and if they are correctly
received. When communicating via LinUDP V2, the drive has no active function, it only responds to requests
with the appropriate answers. LinUDP V2 is a second version of LinUDP, it function on drives with LU
(C1250-LU-XC) in the name. On this drives the old LinUDP version does not run.
2 Installation on Servo Drive
For installing the LinUDP V2 firmware on the servo drive, start the LinMot- Talk software and press the install
firmware button
. Choose the file “Firmware_Buildxxxxxxxx.sct” and press “Open”. The wizard will guide
you through the installation. The installation will install LinUDP V2 on the servo drive if it is a drive with the
letters LU in the name (C1250-LU-XC-xS-000, E1250-LU-UC, E1450-LU-QN-xS or C1450-LU-VS-xS-000).
3 Connecting LinUDP V2
3.1 Pin Assignment of the Connectors X17 - X18
The Ethernet/IP connector is a standard RJ45 female connector with a pin assignment as defined by EIA/TIA

RJ-45
Use standard patch cables (twisted pair, S/UTP, AWG26) for wiring. This type
of cable is usually referred to as a “Cat5e-Cable”.
3.2 Default IP Address Settings
The default IP address is 192.168.001.xxx, where the last byte xxx is defined via the
two hex switches S1 and S2. S1 sets the high and S2 the low digit.
S1, S2
IP Selectors
S1 (5..8)
S2 (1..4)
Bus ID High (0 … F). Bit 5 is the LSB,
bit 8 the MSB.
Bus ID Low (0 … F). Bit 1 is the LSB,
bit 4 the MSB.
Setting the ID high & low to 0xFF
resets the drive to manufacturer
settings!
