USB Communication
Before connecting the controller to a host PC using a standard Micro-B to USB-A cable,
the user should install the application included in the USB Flash Drive that accompanies
the Unit. The application automatically installs the correct USB drivers. Communication
can be done through this interface by using the application or by developing software in
the user's preferred programming language.
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 8743-CL Controller/Driver through the USB port must
be terminated by a <LF> (line feed).
All responses sent by the 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 8743-
CL 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. Please be aware that 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 8743-CL does not support auto-negotiation
of IP addresses. If the network lacks a DHCP server, the 8743-CL 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 8743-CL provides various commands to help setup and tailor Ethernet communication
to most needs. (See below)
