make the values dynamically assigned by a network DHCP server, set IP
Address Assignment to DHCP.
The system name (also known as
host name
or
computer name
), can be
set using remote communications (either Ethernet or RS-232); it cannot
be edited using the front panel keypad.
All network parameters (even those assigned by a DHCP server) can be
viewed using the Net Settings submenu (see page 104).

HARACTERS
All commands and queries are transmitted and received as ASCII values
and are case insensitive. The Model 430 Programmer always transmits
<CR><LF>
(a
carriage return
followed by a
linefeed
) at the end of an
Ethernet transmission. The Model 430 can accept
<CR>
,
<LF>
,
<CR><LF>

SSIGNMENTS
The Model 430 accepts connections to ports 23 and 7180. Port 7180 is
recommended for general command/query operation. When a
connection is successfully established to the Model 430, the following
“hello” message is immediately returned:
American Magnetics Model 430 IP Interface\r\nHello.\r\n
Multiple connections to port 7180 are allowed. Multiple connections to
port 23 are also allowed, but the special broadcast protocol described in
the following section will only occur for the
last connection
made to port
23.

ROTOCOL
Port 23 has a special function in that the display characters are
broadcast each time the display is internally updated by the Model 430.
This occurs approximately every 250 milliseconds. This feature is
intended to allow the user to optionally show a remote display that
remains synced with the front panel display.
The broadcast message format will be as the following example output
(terminated with a <CR><LF> pair):
MSG_DISP_UPDATE:: +50.00 A - Mode: Holding :: 0.00 Vm PSwitch Heater: ON ::0::1::0::1::0::0
