MDX420 SkyWire™ Satellite Network Gateway Front & Rear Panel Interfaces
MN-MDX420 Revision 6 4–5
4.3.3.4 Service Port (J7)
The Service port is a 9-Pin female “D” connector. The service port allows access to the MDX420
Terminal screens. The Terminal screens allow the use of an external terminal for basic monitor and
control of the MDX420. No external software is required other than a VT100 terminal emulation software
(e.g. HyperTerminal or ProComm) when a computer is used as a terminal.
Please Note: The Service port offers a limited set of monitor and control functions and is not intended to
be a full service monitor and control port. Full monitor and control of the SkyWire gateway is supported
via the SNMP Control interface.
The electrical interface of the service port is RS232. The terminal control mode supports VT100 terminal
emulation mode, 19.2 kbaud rate, and must be set for 8 data bit, 1 stop bit and no parity (8, N, 1). .

4.3.3.5 Control Port, Ethernet 10/100 (J1 & J2)
The control port (J1 & J2) is used for the Monitor & Control (M&C) of the gateway. The physical interface
is a standard female RJ-45, Auto-Crossover and Auto-Sensing, 10/100 Connector. Connecting to either
control port is a valid connection for M&C of a single gateway.
