Installation and Setup 2-7
Connecting the E3/T3 Interface
The E3/T3 interface of RIC-E3/ETH and RIC-T3/ETH terminates in two BNC coax
connectors, designated IN and OUT.

To connect E3/T3 interface:
1. Connect the receive line, using a 75Ω coaxial cable to the BNC connector
labeled IN.
2. Connect the transmit line, using a 75Ω coaxial cable to the BNC connector
labeled OUT.
Connecting the Ethernet Interface
The Ethernet interface of RIC-E3/ETH and RIC-T3/ETH terminates in an RJ-45
connector, designated 10/100BASE-T. Table 2-5 lists the RJ-45 connector pinout.

To connect the Ethernet interface:
• Connect the LAN to the RIC-E3/ETH or RIC-E3/ETH port, labeled
10/100BASE-T.

Connecting the Power
To connect RIC-E3/ETH or RIC-E3/ETH to the power source, refer to the
appropriate section below, depending on your version of the unit (AC or DC).
The units have no power switch. Operation starts when the power is applied to
the rear panel POWER connector.
Before switching on this unit and connecting or disconnecting any other cable,
the protective earth terminals of this unit must be connected to the protective
ground conductor of the mains power cord. If you are using an extension cord
(power cable) make sure it is grounded as well.
Any interruption of the protective (grounding) conductor (inside or outside the
instrument) or disconnecting of the protective earth terminal can make this
unit dangerous. Intentional interruption is prohibited.
For the AC version, make sure that only fuses of the required rating, as marked
on the rear panel, are used for replacement. Do not use repaired fuses or
short-circuit the fuse holder. Always disconnect the mains cable before
removing or replacing the fuse. Whenever it is likely that the fuse protection
has been damaged, make the unit inoperative and secure it against unintended
operation.
