2.2 DESCRIPTION
The Patton Model 2065/66RC Interface Converter Rack Card lets
an X.21 DCE to communicate bi-directionally with an RS-232/V.35 DCE
or DTE. Operating synchronously, full or half duplex, the Model
2065/66RC is protocol independent and incorporates two 16-bit elastic
buffers. For extra flexibility, the Model 2065/66RC is DTE/DCE
switchable on the RS-232/V.35 interface (the X.21 interface is
configured as a DTE). Clocking is supplied by the X.21 DCE device.
This interface converter is available in two versions: The Model
2065RC converts from X.21 to RS-232, and supports sync data rates to
128 kbps. The Model 2066RC converts from X.21 to V.35 and
supports sync data rates to 2.048 Mbps. Both versions use Patton’s
mid-plane architecture and are equipped with dual UD-26 connectors
on the rear interface card (adapter cables are available from Patton
Electronics).
The Model 2065/66RC is designed to mount in Patton’s 2U high
19” rack chassis and 2/4/8 slot Cluster Boxes. Available power
supplies include 120/230V AC and 48/24/12V DC. The Model
2065/66RC is made in the USA.

3.0 CONFIGURATION
This section describes the location and orientation of the Model
2065/66RC's configuration switches and jumpers, and details all
possible settings. This section also identifies factory default
configuration settings.
3.1 FRONT CARD CONFIGURATION
The Model 2065/66RC front card uses a single four-position DIP
switch (S1), plus a DCE/DTE strap, to configure the unit for a wide
range of applications. Figure 1 (below) shows the location of switch set
S1 and the DCE/DTE strap on the Model 2065/66RC front card. Figure
2 (below) shows the orientation of DIP switch set S1.
3.1.1 SWITCH SET S1
DIP switch set S1 has 4 switches and is used to define which
control signals will be passed between the two interfaces. Depending
upon the setting of the DCE/DTE strap, the function of the four switches
