For example, the following excerpt from a script file contains address and port assignment
commands for an ESP-2 MI serial hub.
ESP

IP = 10.0.0.115
MAC = 00-80-7D-94-65-00

P2 = COM40

Type and address information
•
The IP address (IP command) is mandatory to uniquely identify the ESP hub, even if the
address is already assigned.
•
The IP and MAC addresses (IP and MAC commands) are both required if the ESP hub does
not yet have an IP address, but is installed on a local subnet.
•
The IP, MAC, gateway and subnet addresses (IP, MAC, GATEWAY and SUBNET com-
mands) are all required if the ESP hub does not yet have an IP address and the hub is not
located on a local subnet.
You may specify an address even if it is not required. For example, if you are updating information
for a previously defined ESP on the local subnet, you may include the MAC address, even though it
is not required.
Physical to logical port numbering
Each physical port number on the ESP hub must be mapped to a logical port number using a
P command.
P<
p_port
>=COM<
l_port
>
For example, in the preceding ESP-2 hub example, physical port 1 was mapped to logical port
COM30 and physical port 2 was mapped to logical port COM40. The specified logical (COM) port
number must be in the range 0-255 and it must be unique; only one physical port may be assigned
to a particular logical (COM) port number.
The current mapping may be obtained from the Windows Device Manager on the ESP property
page and the Starting COM Port listboxes. A current list may also be generated by
entering
espinstall /list
