Remote Command Sequence: *01T042
Response: *01T
For other MITEQ converter types with a remote interface refer to the list of remote
commands for that particular unit. The NSU will pass those commands to the unit and
pass back its response to the NSU.
4.2.25 NSU REMOTE COMMUNICATION EXAMPLE
The following is an example of a properly formatted, typical command and its response
showing the ASCII printable characters. The address is 41H (ASCII code 'A') for these
examples.
Return the number of entries stored in the event log of the NSU. The NSU returns a
response that indicates that there are 3 entries in the event log.
Remote Command Sequence: {A?LOG00}>
Response: {A?LOG03}A
4.3 ETHERNET INTERFACE
The Control Unit is equipped with an Ethernet Interface feature permitting control and
monitoring via a 10 or 100 Mbps Ethernet connection. Available interface protocols are
HTTP (web access), SNMP (Simple Network Management Protocol), and Telnet. In
addition, a capability to remotely upgrade the system firmware is provided.
The use of standard protocols makes it possible to provide (password-protected) access
to the Control Unit from any location in the world where an internet connection is
available
4.3.1 CONNECTION
The NSU is shipped from the factory ready to dynamically assign an IP address. The
unit can be connected to the facility Local Area Network (LAN) network via an industry-
standard 10baseT RJ45 cable. The cable should be a “direct” cable, not a “crossover”
cable.
If the network supports dynamically assigned IP addresses then a valid IP will be
obtained when the NSU is connected to the LAN and the NSU power is cycled. If the
network does not support dynamically assigned IP addresses then a valid IP address
must be obtained from a network administrator and the NSU must be configured to that
static IP address (see Paragraph 4.3.3).
The unit may also be connected directly to a PC without a LAN. To connect directly to
the PC a “crossover” cable must be used. The unit then must be set to a Static IP
address to communicate with the computer (see Paragraph 4.3.3).
