DMC-1400 Series Command Reference IA ● 101
IA FUNCTION: IP Address
DESCRIPTION:
The IA command assigns the controller with an IP address.
The IA command may also be used to specify the time out value. This is only applicable
when using the TCP/IP protocol.
The IA command can only be used via RS-232. Since it assigns an IP address to the
controller, communication with the controller via internet cannot be accomplished until
after the address has been assigned.
ARGUMENTS: IA ip0,ip1,ip2, ip3 or IA n or IA<t where
ip0, ip1, ip2, ip3 are 1 byte numbers separated by commas and represent the individual fields
of the IP address.
n is the IP address for the controller which is specified as an integer representing the signed
32 bit number (two’s complement).
<t specifies the time in update samples between TCP retries. (TCP/IP connection only)
>u specifies the multicast IP address where u is an integer between 0 and 63. (UDP/IP
connection only)
IA? will return the IP address of the controller
