Section 2 Installation & Setup
eCDi ™
2.3 Connection Overview
The following connections will need to be made to make the eCDi™ work:
NOTE:
Detailed information concerning the following connections is given in the
individual transmitter install procedures later in this section. See "2.4 Detailed
Installation Procedures by Transmitter" on page 2-4.
a. AC Power - eCDi™ is powered from a standard ac wall cord, 110/220Vac (auto-
switching). Do not turn the eCDi on at this time.
b.
A short ethernet jumper cable is provided with the eCDi™ . It connects the com-
puter LAN port to the Uplink port of the internal 5 port switch. It must be con-
nected in the position shown in Figure 2-2. This is the hardware or transmitter
LAN side of the eCDi™ .
NOTE:
For security reasons, the LAN port must never be connected to an outside
network. These are only to be used for connection to equipment or for local
configuration of the eCDi™ itself.
c.
The leftmost Ethernet connection is the WAN connection. This should be con-
nected to the Station LAN or WAN or possibly a LAN modem if the only connec-
tion to the site is via dial-up phone line. For more information on setting IP
addresses for this port see "2.8 eCDi™ Configuration" on page 2-26.
d.
XMTR (male D connector) connects to the transmitter controller serial port.
e.
Exciter (male D connector) is for serial connection to CD-1A exciters in DTV
transmitters. To connect 2 exciters, this cable must have a “Y” adaptor installed.
f.
The 2 Ethernet connections labeled EX1 and EX2 will be connected primarily to
exciters with ethernet ports, such as APEX™ .
