EDACS Addresses
There are two types of EDACS Addresses, Logical IDs (LIDs), and Group IDs (GIDs). LIDs are used to
reference a single radio. GIDs are used to reference a group of radios. LIDs and GIDs are programmed into
radios and can be changed as desired.

In Data Advantage, there are two categories of radios: Data Host Radio and RDT radio. A Data Host Radio is
fixed RF equipment housed in the Data Advantage cabinet called RF control station. An RDT radio is connected
to a Radio Data Terminal which is mobile RF equipment. A Data Host Radio must be assigned a LID in the range
1-63. The LID assigned to an RDT should be in the range 64-16382. It is not recommended to assign a LID in the
range 1-63 to an RDT radio, even though it is allowed in the EDACS.

Ethernet Addresses
Ethernet Addresses are 48-bit addresses assigned by hardware vendors. Normally, an Ethernet Address is
permanently assigned to a hardware device. The Address Resolution Protocol (ARP) that is built into the
Internet Protocol allows devices to query each other for their Ethernet Address. For these reasons, Ethernet
Addresses are of minor importance when setting up a network, and are not discussed in detail.
