4.2 CONNECT TO THE DTE INTERFACE
The DTE interface is a V.35 DTE (M/34 male connector),
designed to plug directly into a DCE interface (See Appendix
C V.35 Interface Pin Assignments).
4.3 POWER CONNECTION
The Model 2135 offers either an AC or DC power supply.
4.3.1 AC Power Supply (100-240VAC)
The Model 2135 uses a 5VDC, 2A universal input 100-
240VAC, power supply (center pin is +5V). The universal
input power supply is equipped with a male IEC-320 connec-
tor. This power supply connects to the Model 2135 via a bar-
rel jack on the rear panel. A variety of international power
cords are available for the universal power supply.
The Model 2135 powers up as soon as it is plugged into
an AC outlet. The unit does not have a power switch.
4.3.2 DC Power
Supply DC power directly to the power supply jack. DC
power supplied must be +5VDC ±5%, 500mA minimum, cen-
ter positive, and can be supplied via a barrel type plug with
2.1/5.5/10mm I.D./O.D./Shaft Length dimensions.
4.0 INSTALLATION
The 2135 is equipped with DTE, Network, and power inter-
faces. This section briefly describes connnection to each inter-
face.
4.1 CONNECT TO 10BASET ETHERNET PORT
The shielded RJ-45 Ethernet port on the Model 2135 is
designed to connect directly to a 10BaseT network. Figure 3
shows the 10BaseT RJ-45 port pin description. You may make
connections up to 3 feet using type 4 or 5 cable.
4.1.1 Connect the 10BaseT Ethernet Port to a Hub
The Model 2135 10BaseT interface is configured as DTE
(Data Terminal Equipment). Use the diagram below to construct a
cable to connect the 2135 to a 10BaseT Hub.

4.1.2 Connect the 10BaseT Ethernet Port to a PC (DTE)
The Model 2135 10BaseT interface is configured as DTE
(Data Terminal Equipment). To connect the 2135 to another DTE
such as a 10BaseT network interface card in a PC, construct a
10BaseT crossover cable as shown in the diagram on the follow-
ing page.
