RS232/V.35 Connector
The RS232/V.35 (DB-25) connector is used to connect the ProxyServer to an external modem, DSU,
or other Data Communications Equipment (DCE). This connection can be either RS-232C (default) or
V.35. If the connection is V.35, then an internal shunt must be moved from its default RS-232 position
to the V.35 position on the printed circuit card assembly (for details on this procedure, refer to
Chapter 2 - V.35 Shunt Procedure).
56K DSU Connector
The 56K DSU connector is used to connect the ProxyServer to a DDS four-wire network connection.
This connector is an RJ-45 jack.
10BASET (Ethernet) Connector
The Ethernet 10BASET connector is used to connect the ProxyServer to a LAN using unshielded
twisted cable. This connector is an RJ-45 jack.
COMMAND Connector
The Command connector is used to configure the ProxyServer using a PC with a serial port and
running Windows® software. The Command connector is an RJ-45 jack and a short adapter cable is
provided to convert to a standard serial DB-9 female connector.
POWER Connector
The Power connector connects the external power supply to the ProxyServer. The Power connector
is a 6-pin circular DIN connector. A separate standard computer power cord connects the power
supply to a live AC grounded outlet.
