Ethernet Peer-to-Peer Setup
Peer-to-Peer Ethernet connection means connecting your 8743-CL 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.
5.4.4
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 8743-CL-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 a Save
(SM) and Reset (RS) command to controller for the new hostname to take effect.
