appendixA,“EthernetConnection”,formoredetails).Iftheaddresseshavenot

been changed, the factory-speciﬁed defaults are:

• IPaddress 192.168.254.254

• Gatewayaddress 0.0.0.0

• Subnetmask 255.255.0.0

Establishing a connection

EstablishanetworkconnectiontoaCrossPointorMAVPlusswitcherasfollows:

1. OpenaTCPsockettoport23usingtheswitcher’sIPaddress.

N

If the local system administrators have not changed the value, the factory-

speciﬁed default, 192.168.254.254, is the correct value for this ﬁeld.

The switcher responds with a copyright message including the date, the name

oftheproduct,rmwareversion,partnumber,andthecurrentdate/time.

N

If the switcher is not password-protected, the device is ready to accept SIS

commands immediately after it sends the copyright message.

N

If the switcher is password-protected, a password prompt appears below the

copyright message.

2. Iftheswitcherispasswordprotected,entertheappropriateadministratoror

user password.

 Ifthepasswordisaccepted,theswitcherrespondswithLogin User or

Login Administrator.

 Ifthepasswordisnotaccepted,thePassword prompt reappears.

Connection Timeouts

The Ethernet link times out after a designated period of time of no communications.

Bydefault,thistimeoutvalueissetto5minutesbutthevaluecanbechanged.See

theCongureporttimeoutcommandsonpage4-25.

N

Extron recommends leaving the default timeout at 5 minutes and periodically

issuing the Query (Q) command to keep the connection active. If there are long

idle periods, Extron recommends disconnecting the socket and reopening the

connection when another command must be sent.

Number of connections

ACrossPointorMAVPlusswitchercanhaveupto200simultaneousTCP

connections, including all http sockets and Telnet connections. When the

connection limit is reached, the switcher accepts no new connections until some

have been closed. No error message or indication is given that the connection limit

hasbeenreached.TomaximizeperformanceofanIPLinkdevice,thenumberof

connections should stay low and unnecessary open sockets should be closed.
