Ethernet Peer-to-Peer Cabling

Peer-to-Peer Ethernet connection means connecting your 8742 directly to your PC
without the use of a router. This may or may not require the use of a special
Ethernet 'crossover' cable as many new computers no longer require it.
An Ethernet crossover cable is a type of Ethernet cable used to connect computing
devices together directly. Normal straight through or patch cables were used to
connect from a host network interface controller (a computer or similar device) to
a network switch, hub or router. A cable with connections that "crossover" was used
to connect two devices of the same type: two hosts or two switches to each other.
Owing to the inclusion of Auto-MDIX capability, modern implementations of
the Ethernet over twisted pair standards usually no longer require the use of
crossover cables. Refer to Section 5.4.2 for how to setup a peer-to-peer connection.

Communicating Using a Hostname

The hostname (HOSTNAME) command is used to set the controller's hostname. A
hostname is a label or nickname assigned to a device connected to a computer
network and is used to identify the device in various forms of communication. This
feature enables users to assign the controller a more easily identifiable name,
perhaps linked to its actual function in an application (e.g., TIPTILT, MIRROR-2).
This command is more common with Ethernet but can also be used with USB
communication.
NOTE: Send Ethernet commands via USB interface as Ethernet
communication may become unstable during Ethernet settings configuration.
While connected via USB, use the Picomotor application software to send
commands (Go to 'Terminal' tab).
The default hostname for the controller is 8742-serialnum, where serialnum is the
controller's serial number. The hostname can have a maximum of 15 alphanumeric
characters. The first character in the hostname cannot be a hyphen ("-"). Issue Save
(SM) and Reset (RS) commands to controller to take effect.
