If this product fails or does not perform as warranted, your sole

1.1 RADIO AND TV INTERFERENCE

The Model 2041 generates and uses radio frequency energy, and if
not installed and used properly—that is, in strict accordance with the
manufacturer's instructions—may cause interference to radio and
television reception. The Model 2041 has been tested and found to
comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that
interference will not occur in a particular installation. If the Model 2041
does cause interference to radio or television reception, which can be
determined by disconnecting the Model 2041, the user is encouraged to
try to correct the interference by one or more of the following measures:
moving the computing equipment away from the receiver, re-orienting
the receiving antenna and/or plugging the receiving equipment into a
different AC outlet (such that the computing equipment and receiver are
on different branches).

1.2 CE NOTICE

The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the Union European
(EU). A Certificate of Compliance is available by contacting Technical
Support.

1.3 SERVICE

All warranty and nonwarranty repairs must be returned freight
prepaid and insured to Patton Electronics. All returns must have a
Return Materials Authorization number on the outside of the shipping
container. This number may be obtained from Patton Electronics
Technical Service at [phone], http://www.patton.com, or at

2.1 FEATURES

• Bi-directionally converts between X.21 and HSSI.

• Supports synchronous data rates up to 10Mbps.

• Transparent to synchronous protocol.

• DB-15 and HD-50 connectors with integral 6-foot (1.8m) cable.

• Two versions available:
Model 2041FT-MC: Connects X.21 (DCE) to HSSI (DTE)
Model 2041FC-MT: Connects X.21 (DTE) to HSSI (DCE)

• Internal synchronization circuit enables high speed connections

• Externally AC powered.

• Made in the U.S.A.

2.2 DESCRIPTION
The Model 2041 is a X.21 to High Speed Serial Interface (HSSI)

converter that lets a device with an X.21 interface communicate bi-

directionally with a device that has an HSSI interface. Operating up to
a top synchronous data rate of 10Mbps, the 2041 is a perfect problem
solver for mismatched interfaces.

The Model 2041 is available in two versions: The Model 2041FT-

MC lets a X.21 DCE device communicate with a HSSI DTE device.
The Model 2041FC-MT lets a X.21 DTE device communicate with a
HSSI DCE device.

All versions are equipped with a female DB-15 connector on the

converter end, and a male HD-50 on the end of a 6-foot (1.8 m) cable.
Other connector genders and cable lengths are available on a custom
basis. Power is supplied to the Model 2041 by an external desktop AC
transformer.

3.0 CONFIGURATION

The Model 2041 is easy to install and is ruggedly designed for
excellent reliability. The following instructions will help you set up and
install the Model 2041 properly.

To use the Patton Model 2041, you must first configure the unit for
your application. To do so, first open the case by inserting a flat head
screw driver into an open slot on either side of the case, as in Figure 1.

Figure 1: Using a Small Screw Driver to Open the Model 2041 Case

Twist the screw driver head slightly and the top half of the case will
separate from the lower half, as in Figure 2. You now have access to
the internal switches used to configure the unit.

Figure 2: Using a Small Screw Driver to Open the Model 2041 Case

After opening the case, please refer to the section that pertains to
your unit for configuration details:

Patton Model Number Section

Model 2041FT-MC ....................................................3.1

Model 2041FC-MT ....................................................3.2

To close the case, fit the 2 halves together snugly and snap them
back in place.

3.1 CONFIGURATION SWITCHES (MODELS 2041FT-MC)

The Model 2041FT-MC has miniature DIP switches that you may
use to configure the units. Each Model 2041FT-MC is factory
configured as DTE on the X.21 end, and DCE on the HSSI end.
Therefore, the X.21 end “wants” to plug directly into a DCE device.
Conversely, the HSSI end of the converter “wants” to plug directly into
DTE.

Please use this section to configure the internal DIP switches so
that the unit will work properly in your application. Figure 3 shows the
position of Switch S1 on the top side of the PC board.
