• This device contains no user serviceable parts. This  
device can only be repaired by qualified service person-  
nel.  
• Do not open the device when the power cord is con-  
nected. For systems without a power switch and without  
an external power adapter, line voltages are present  
within the device when the power cord is connected.  
• For devices with an external power adapter, the power  
adapter shall be a listed Limited Power Source. The  
mains outlet that is utilized to power the device shall be

2.2 DESCRIPTION  
The Patton Electronics Model 2172A CopperLink modems provide high-  
speed LAN connections between peered Ethernet LANs, remote PC’s, or  
any other network enabled 10/100Base-T device.  
Operating in pairs, one Model 2172A is configured as the (L) Local unit  
located at one end of the LAN extension and the other Model 2172A is  
configured as the (R) Remote unit at the other end. The Model 2172A is  
configured as a L or R via the switch on the bottom of the unit.These units  
can automatically forward LAN broadcasts, multicasts, and frames across  
a 2-wire voice-grade twisted-pair link. The data is passed transparently  
(unmodified) through the 2172As. The 2172As automatically add and  
delete MAC addresses, only passing packets across the CopperLINK link  
that are meant for the remote peered LAN.

The Interconnecting cables shall be acceptable for  
external use and shall be rated for the proper applica-  
tion with respect to voltage, current, anticipated tem-  
CAUTION  
perature, flammability, and mechanical serviceability.  
The Model 2172A supports communication between two peer Ethernet  
LAN sites over a distance of up to 4,250 ft (1.3 km) over 24 AWG  
(0.5 mm) twisted-pair wire.  
Note Actual distance and link performance may vary depending on  
the environment and type/gauge of wire used.  
Follow the steps below to connect the Model 2172A CopperLINK Inter-  
faces.  
Note The Model 2172A units work in pairs. One of the units must be  
configured as a (L) Local unit, and the other unit must be config-  
ured as a (R) Remote unit. It does not matter which end is the L  
and which is the R. The link is always initiated by the R unit. As  
long as the L unit is powered on, the R unit can establish a link  
by being powered on or by having its power reset.

1. To function properly, the two Model 2172As must be connected  
together using twisted-pair, unconditioned, dry, metal wire, between  
19 (0.9mm) and 26 AWG (0.4mm). Leased circuits that run through  
signal equalization equipment are not acceptable.  
2. The Model 2172A is equipped with an RJ-45 interface jack that can  
be used on the CopperLINK interface. The CopperLINK interface is a  
two-wire interface. Observe the signal/pin relationships on the Model  
2172A's CopperLINK interface jack.  
The RJ-45 connector on the Model 2172A's twisted pair interface is  
polarity insensitive and is wired for a two-wire interface. The signal/pin  
relationship is shown in Figure 3.

external use and shall be rated for the proper applica-  
tion with respect to voltage, current, anticipated tem-  
perature, flammability, and mechanical serviceability.  
CAUTION  
The Model 2172A does not have a power switch, so it powers up as soon  
as it is plugged in.  
An external AC or DC power supply is available separately. This connec-  
tion is made via the barrel jack on the rear panel of the Model 2172A. No  
configuration is necessary for the power supply (See Appendix B for  
domestic and international power supply and cord options).  
DC power (supplied via the power supply jack to the 2172A) must meet  
the following requirements; DC power supplied must be regulated  
+5VDC 5%, 1.0A minimum. Center pin is +5V. The barrel type plug has  
a 2.5/5.5/10mm I.D./O.D./Shaft Length dimensions.  
4.0 CONFIGURATION  
The Model 2172A has four DIP switches (S1) for configuring the unit for a  
wide variety of applications. This section describes switch locations and  
explains the different configurations.
