130-SMHR/9 Net Connector

Communications between the 130-SMHR/9 and a remote system using either external TCP/IP
and/or an optional external modem occur across the 130-SMHR/9 NET connector. The cable has
two connectors to allow two connections, one for Ethernet and one for serial communications.
The internal modem must be removed before using an external modem. See Section 2 in this
manual for a procedure on removing the internal modem.
CAUTION: A 130-SMHR/9 is shipped pre-configured with a default IP address. Be sure to
change this address before connecting the 130-SMHR/9 to an Ethernet port. Any IP
addresses on one of the same subnets, as the 130-SMHR/9 unit, may connect using FTP
and/or the command socket. However, the 130-SMHR/9 unit restricts the external IP
addresses from which it will accept connections, to the equivalent of a Class C subnet
containing the RTP host. If no RTP host is set for an interface, no connections can be
established to the unit from outside its subnet.
The 130-SMHR/9 uses a 10BaseT Ethernet chip. The 130-SMHR/9 Ethernet port may not
work when connected to all 100BaseT and some 10/100BaseT Ethernet hubs.
