42 Computer Interfacing
The USB Flash Drive contains communication drivers and software for operating
the controller/driver.
5.3.1 USB Command Termination
Commands and queries sent to the 8742 Controller/Driver through the USB port
must be terminated by a <LF> (line feed).
All responses sent by the 8742 Controller/Driver are terminated with a <LF> (line
feed).
5.4 Ethernet Communication
The default Ethernet configuration should work for most users. Simply connect the
8742 controller to your Ethernet router, install and run the Picomotor application
software that came with the product. After a few seconds, mostly depending on
network TCP/IP negotiation with router and/or computer, the software should
automatically ‘discover’ the controller on the network and Picomotor control may
begin. Be aware the computer will not be able to discover the controller if the
network does not have a DHCP server (included in most routers) because the 8742
does not support auto-negotiation of IP addresses. If the network lacks a DHCP
server, the 8742 must be configured for static IP addressing.
This controller supports the following network protocols: IP, TCP, UDP, ICMP,
DHCP, PPP, ARP. Additionally, Sockets interfacing is supported.
The 8742 provides various commands to help setup and tailor Ethernet
communication to most needs. (See below)
