Setting Network Address & Loop and Unit Numbers
Description
This section provides instructions to configure an Advance Network
Gateway (ANG_EN) with its own Network Address.
Before You Begin
1. Open Windows Hyper Terminal program on your PC; reference
Configuring Your PC, page
26.
2. Connect and Log on to ANG_EN; reference Establishing a
Connection, page
30.
Important Definitions
Familiarize yourself with the following definitions.
This is the 12-digit address that defines each
ANG_EN’s network ID and host ID. The IP
address must be assigned before the ANG_EN is
placed on-line to the network. Typically the
customer’s network administrator assigns this
address. The address ip is entered in dotted
decimal notation. Ex: xxx.xxx.xxx.xxx
address ip:
Subnetting, dividing the host ID into a subnet and
host ID, helps hide the details of an internal
network organization to external routers. The
subnetmask is used to reduce the size of routing
tables and restrict broadcast messages to the
subnetwork. The subnetmask is a 32-bit value
containing one bit for the network and subnet ID
and zero bits for the host ID. Typically the same
subnet mask is used on all ANG_ENs on a given
network. Ex: 255.255.000.000.
subnetmask:
This is the 48-bit unique Ethernet address. This
address is assigned at manufacturing time and is
not user configurable.

Loop refers to the Advance Data Hiway (ADH)
Loop number. Each ANG must be assigned a
Loop number. All ADH units physically connected
to the same bus as the ANG must have the same
Loop number. Allowable Loop numbers range
from 1 - 8.
