If the connected network does not have DHCP enabled, then the device can be assigned an IP address by the
user. To do this, download the utility called DeviceInstaller
TM
. For assistance
using this utility please consult the utilities embedded help file.
The DeviceInstaller
TM
utility will scan the network and find all connected Lantronix Ethernet devices. This
list of found devices will include any connected AR Ethernet devices. By selecting one of the connected
devices from the list, its IP address and subnet mask can be changed along with a number of other settings.
One should use caution in adjusting any settings he/she is unfamiliar with as doing so may cause the port to
become unresponsive. By default the port for the TCP data channel is 10001.
* DHCP is a protocol used to assign a dynamic IP address to a device. Network server software will assign
an available IP address to a device when it is connected and powered on. Different IP addresses may be
assigned at different times.

Remote Commands
•
If a command or query is unrecognized it is echoed back out the port it came in on.
•
All commands and queries are terminated with a Line Feed character.
•
A Line Feed character is indicated by <LF> in subsequent command and query definitions.
•
All queries can be sent when the Keylock switch is in the INHIBIT, LOCAL, or REMOTE position.
•
All commands can only be sent when the Keylock switch is in the REMOTE position.
•
All spaces in command and query definitions are indicated by <space>.
•
If a query is recognized, its associated response is echoed out the port it came in on.
A
COMMUNICATIONS_ERROR
<LF> can occur if the time between commands or queries is too short, or
the internal RS-485 link between the IO Board assembly and the Multipurpose Board (MPB) assembly is
broken.
The development of application programs requires an understanding of the operation of the amplifier as well
as the intended application.
An application program on the computer/controller should issue only one character string (command or
query) at a time. After each functional command is issued, the amplifier’s status should be checked to ensure
that the command has been properly executed. The application program should allow sufficient time for the
function to be completed before checking the status.
The application program should facilitate the checking of the status just prior to issuing a command, since the
status could have been changed by a fault condition or by operator actions.
Variables represented by wild card characters i.e. x, y, z etc. do not indicate or delimit the number of
characters actually specified.
