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:
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.
