 Configuration
This section explains how to configure the custom Ethernet object in the reader. The Custom Ethernet
Link K Command
<K166>
allows you to configure the custom Ethernet object in the reader.
The following section explains the command parameters that configure the custom Ethernet object.
Note that each parameter described below corresponds with each parameter shown in the
Custom
Ethernet Link
section of WebLink's
Communications
menu shown at the beginning of this topic.

 Status
<K166,status
,
transport layer,type,capabilities,IP address,multicast address,port,check
connection,timeout milliseconds,TTL>
Status of the custom Ethernet object in the device.
0 = Disabled Default
– The custom Ethernet object is not started.
1 = Enabled
– The custom Ethernet object has started with the parameters configured.
 Transport Layer
<K166
,status,
transport layer
,
type,capabilities,IP address,multicast address,port,check
connection,timeout milliseconds,TTL>
The transport layer used by the custom Ethernet object to send/receive data. This transport layer obeys
the OSI Model layer 4. The multicast implementation uses UDP User Datagram Protocol as the
transport layer.
0 = TCP Default
1 = UDP
2 = Multicast

This is the how the feature runs on the device and follows the server client model.
0 = Server Default
– In server mode the device will be listening on the configured port number. The
server can handle up to 10 different connections at one time independent of the transport layer
selection. Once the limit has been reached the server will reject other connections.
For Multicast server configuration you can either use a specified Multicast address or leave the
Multicast address to the configured Multicast APIPA Address. This Multicast address is safe to use
according to RFC 4607 stating that Multicast ranges from 232.0.0.0 – 232.255.255.255 are okay to use
for source specific applications. By default, the unit creates a unique Multicast address in the range of
232.169.xxx.xxx so it does not conflict with other multicast addresses.
1 = Client
– In client mode the device will send data to the specified server. You must configure the IP
Address or Multicast Address of the server and the port number that the specified server is listening on.
Improper configuration will either yield an error on startup or result in no data being transmitted from the
device to the outside world.

Capabilities
is how you configure the custom Ethernet object's read/write settings.
1 = Receive
– The device will only receive data from the connecting endpoint. The device will not send
data out to any connecting endpoints.
2 = Send
– The device will only send data to the connecting endpoint. Any data received is immediately
disposed of and not processed.
3 = Send/Receive Default
– The device will be able to send and receive data to the connecting
endpoint.
