Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Network Configuration
Overview
DXLink Modules support two IP Addressing Modes: Static IP and DHCP (with link-local fallback*).
To avoid having a large system consume numerous IP addresses, the Transmitter and Receiver default to disabling the
network connection functionality. Therefore, the #3 Toggle
must
be set to ON before the Transmitter or Receiver can
establish a network connection (see page 45).
When #3 Toggle is ON, the DXLink Modules are automatically placed in DHCP Mode, but they can be configured for
either of the IP Addressing Modes via two methods:
The front-panel ID Pushbutton (see page 67)
Telnet commands (see page 108)
*
“Link-local fallback” is a method by which an IP host, as a fallback from DHCP, can derive a local network-unique IP
address by negotiating with the other IP hosts on the same network. Link-local can also be used in its own right as the
primary method of IP address allocation. For details, see “DHCP Mode” below.
Static IP Mode – Default Parameters
Important:
Static IP Mode will not function until the #3 Toggle on the DIP switch is set to ON (see page 45).
The #3 Toggle must be ON before the device is accessible via SEND_COMMANDs.
DHCP Mode
Important:
DHCP Mode will not function until the #3 Toggle on the DIP switch is set to ON (see page 45). The
#3 Toggle must be ON before the device is accessible via SEND_COMMANDs.
DHCP Mode requires a connection to a network with a DHCP server located on it. This connection can be either indirect
or direct.
Indirect connection – In the case of an Enova DGX Digital Media Switcher or an Enova DVX Solution
(Endpoint Mode) that is connected to a DHCP server device, the DHCP connection can be propagated
through the system’s DXLink layer. First you
must
complete the following:
Set the #3 Toggle to ON to enable the network connectivity.
Direct connection – In the case of a standalone pair (Extender Mode), to place the DXLink Modules in DHCP
Mode you
must
complete the following:
Set the #1 Toggle to ON to enable access to the physical ICS LAN 10/100 port.
Set the #3 Toggle to ON to enable network connectivity (DHCP).
Connect the ICS LAN 10/100 port to a network where a DHCP server is located.
