WEMPE ENI 

secondary clocks interface

Installation

1.1  Configuration

 

The Wempe Ethernet Slaveclock consists of two parts:  The mechanical clock and the electronic 
Ethernet Network Interface (ENI). The arms of the slave clock are self adjusting and pre setted 
already. Normally no further administration or commissioning is necessary. If other than the default pre 
settings are desired, the ENI can be administrated using the ENI web interface.  

Please use a browser to enter the web interface: 

http://ENI-IP-ADDRESS

 . Now you have access to all 

the adjustments. The standard login data you can find in the owners manual or ask your IT office.  

The manufacturer pre-set IP address is shown on the ENI's label.  (172.16.n.n / 255.255.0.0) 

Be sure to select the correct compatibility mode. Possible settings are: Master Clock 20100, 
20101 or 20102: 

Supported LAN parameters: IP address, subnet mask, gateway address, primary and secondary NTP 
server (not at ENI V1 legacy mode). 

The allocation of IP addresses is static by default. This can be changed to obtain addresses from a 
DHCP server. The DHCP query asks for addresses of NTP servers, too. If the DHCP server provides 
them, up to two addresses will be mentioned by the ENI configuration. 

1.2  Ethernet network connection 

The  ENI  is  designed  for  operation  via  a  PoE  switch.  This  means  that  the  power  supply  and  data 
communication  is  provided  by  the  same  device.  Alternatively,  24VDC  power  can  also  be  supplied  to 
the ENI via the terminal block.  

Attention: Do NOT connect at the same time Power over Ethernet 

AND the external 24 DC power supply. 

1.3  Setting up the Master Clock connection 

The network configuration depends on the type of time source / master clock. 

The first steps are common for all connection types: 

Open a web browser and navigate to the URL shown on the ENI's label as IP address.

Proceed to the Configuration page, give username and password (see chapter 3).

If desired, change the individual static IP address or enable the DHCP client and figure out the

P address the ENI obtained from the DHCP server.

Set a location name to identificate the ENI in the Master Clock database easily.
