This warranty is limited to defects in workmanship or materials,
and does not cover customer damage, abuse or unauthorized
modification. If this product fails or does not perform as warranted,
your sole recourse shall be repair or replacement as described above.
Under no condition shall Patton Electronics be liable for any damages
incurred by the use of this product. These damages include, but are
not limited to, the following: lost profits, lost savings and incidental or
consequential damages arising from the use of or inability to use this
product. Patton Electronics specifically disclaims all other warranties,
expressed or implied, and the installation or use of this product shall be
deemed an acceptance of these terms by the user.
1.1 RADIO AND TV INTERFERENCE
The Model 2016 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 2016 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 2016
does cause interference to radio or television reception, which can be
determined by disconnecting the X.21 interface, 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.

2.1 FEATURES
• Bi-directionally converts synchronous X.21 to V.35
• Supports data rates to 2.048 Mbps
• Half or Full Duplex Operation
• Transparent to protocol
• No AC power or batteries required
• DB-15 and M/34 connectors with integral 6 foot cable
• Circuitry housed in ultra-miniature case
• Made in the USA
2.2 DESCRIPTION
The Model 2016 X.21 to V.35 Converter lets synchronous X.21
devices communicate bi-directionally with synchronous V.35 devices -at data rates up to 2.048 Mbps. Operating full or half duplex, the Model
2016 passes all necessary clocking and control signals, and is
transparent to synchronous protocol. DTE and DCE configurations are
available.
The Model 2016 connects directly to the synchronous X.21
interface using a male or female DB-15 connector. A male or female
M/34 connector plugs into the V.35 interface.
Housed in an ultra-miniature ABS plastic case, the Model 2016 fits
easily into tight locations. The Model 2016 is manufactured by Patton
Electronics in the USA.

3.0 INSTALLATION
The Model 2016 is designed to be easy to use. Since there is
nothing to configure, all you need to do is plug the Model 2016 into the
proper device ports.
The Model 2016XT-XC is factory configured to connect an X.21
DCE device to a V.35 DTE device. Figure 1, below, illustrates proper
connection of the Model 2016 in a wide area networking application.
The Model 2016XC-XT is factory configured to connect an X.21
DCE device to a V.35 DTE device. Figure 2, below, illustrates proper
connection of the Model 2016 in a wide area networking application.

4.3 CONNECTING POWER (MODEL 2016XC-XT ONLY)*
Under normal conditions, the Model 2016XC-XT requires no
additional power to operate. It simply derives its operating power from
the data and control signals. However, in certain low-power conditions,
additional power may be necessary. The Model 2016XC-XT offers
three alternatives to supplying external power: 1) Using the DC
Adapter; 2) Supplying DC directly to to the PC board; and, 3) Suppling
Power through the V.35 Interface.
NOTE: Model 2016XT-XC does not require additional power to
operate.
4.3.1 Using the DC Power Supply
The Model 2016XC-XT uses a 7.5VDC, 1.2A universal input, power
supply that is equipped with a male IEC-320 power entry connector
and supports a voltage range of 100-250VAC. This power supply
connects to the Model 2016XC-XT by means of a barrel 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
2016XC-XT powers-up as soon as it receives adequate DC powerthere is no power switch.
4.3.2 Supplying DC Power Directly to the PC Board
You may bypass the DC wall adapter and supply DC power directly
to the Model 2016XC-XT power supply jack. DC power supplied must
be 7.5 - 12VDC ±5%, 100mA 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.
4.3.3 Supplying Power via pin KK
You may also supply DC power directly to pin KK of the V.35
interface. DC Power supplied to pin KK must be 7.5 - 12VDC, 100mA
minimum.
NOTE: DC power source must be SELV (Circuit, Safety Extra Low
Voltage) specified. (See CENELEC EN60950, Section 1.2.8.5)
4.4 LED STATUS INDICATORS (MODEL 2016XC-XT ONLY)
The Model 2016XC-XT features two LEDs that are located on the
back panel. Figure 3 below shows the positions of the LEDs.
Following Figure 3 is a description of each LED.
Supplemental Power LEDs
DC Power Jack Glows red to indicate that the 2016XC-XT is
receiving operating power by means of the
external power-jack (See Sections 4.3.1 and
4.3.2).
Interface Power Glows green to indicate that the 2016XC-XT
is receiving operating power via pin KK on
the V.35 interface (See Section 4.3.3).
