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.

Switches S1 and S2: Synchronization Method

Set Switches S1 and S2 together to allow the Model 2041FT-MC to
compensate for timing delays when transmitting HSSI data at high
speeds (greater than 2.5 Mbps). At high bit rates, set Switch S1 On
and Switch S2 Off. In this setting, HSSI data will be synchronized to
the Signal Element timing signal from the X.21 side before being
converted to X.21 data. At lower bit rates (less than 2.5 Mbps), set
Switch S1 Off and S2 On. In this setting, the X.21 data bypasses the
synchronization circuit and passes straight through to the HSSI DTE.

3.2 CONFIGURATION SWITCHES (MODELS 2041FC-MT)

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

Please use this section to configure the internal DIP switches so
that the unit will work properly in your application. Figure 5 shows the
position of Switch S1 on the top side of the PC board.

4.3 AC POWER CONNECTION

The Model 2041 uses a 5VDC, 2A universal input, power supply
that is equipped with a male IEC-320 power entry connector and
supports a voltage range of 100-250VAC. This transformer connects
to the Model 2041 by means of a cannon jack on the rear panel. There
are a variety of domestic and international power cords available for the
power entry (See Appendix B). The Model 2041 is powered-up as soon
as it is plugged into an AC outlet–there is no power switch.

4.4 DC POWER CONNECTION

You may bypass the DC wall adapter and supply DC power directly
to the Model 2041 power supply jack. DC power supplied must be
5VDC ±5%, 1A minimum, center positive, and can be supplied via a
barrel type plug with 2.1/5.5/10mm I.D./O.D./Shaft Length dimensions.

NOTE: DC power source must be SELV (Circuit, Safety Extra Low

Voltage) specified. (See CENELEC EN60950, Section 1.2.8.5)
