subnet, iparpst, udpast, pwrst,”
Description: When a module receives this broadcast command (by continuously monitoring
port 7000) it responds with a broadcast (on port 7001) with an ASCII response
containing comma-separated parameters. These are listed in the following table
:
Parameter Meaning
ipadr
IP address
ethadr
Ethernet address
sernum

sfwver
Software version (e.g., x.xx decimal format)
connst
Connection status (1=connected, 0=available)
ipadrst
IP address status (1=has one, 0=waiting for server)
lisport
IP listening port for connections (default=9000)
subnet
Subnet mask
iparpst
IP address resolution status (1=uses RARP/BOOTP server, 0=uses
static IP address stored internally)

UDP auto status (1=broadcasts this response automatically after
connection possible, 0=only sends response for “psi9000" UDP/IP
command.
pwrst
