Connecting the Serial Data Port
The serial data por t can be used for a single serial CEA-708 caption per SMPTE 333 per
chassis. Connect a DB-9 connector from a device generating CEA-708 closed captions. For
DB-9 pinouts see RS-232 Serial Port Pinouts.
NOTE: The serial data port should only be used in a single serial SMPTE 333 (carrying CEA-708
captions) link per chassis.
Cabling Optional Modules
Depending on your encoder configuration, follow the instructions for cabling the optional
module or modules installed in your encoder chassis. These can include:
n Audio modules (Connecting the AHC-RAC Audio Input Cables and AHC-561 Module)
n FLEX decoding module (Cabling the FLEX-1 Module)
q RF (8VSB) input module (RF Module Specifications)
q ASI input module (ASI Input Specifications)
Connecting the Power
The encoder is customized with either a DC power supply or up to two AC power supplies.
Instructions for both are included in this section:
n Connecting an AC Power Supply
n Connecting the DC Power Supply
The chassis does not have a power switch. The unit powers on automatically when you plug it
in.
Before you power-up the encoder, make sure that you have performed all of the cabling
required for each of the optional modules that are installed.
To power-up the encoder:
1. Connect the power cord to the power plug on the encoder back panel and connect the
power cord to the power outlet.
2. The boot sequence begins, as described in Local Control Panel Display Messages during Bootup
Connecting an AC Power Supply
The encoder is equipped with one or two AC power supplies that use autosensing to adjust to
different incoming voltages. The AC power plugs accommodate standard IEC 120 VAC and
250 VAC power cords.
For Electra 9200 single power supply models, the fuse panel is located beside the power
plug. The encoder requires one slow blow 6.3 A, 250 V fuse,5x20mm.
NOTE: No fuse is available on the dual power supply model of the Electra 9200 (ELC-9200D).
CAUTION: This product relies on the building’s electrical installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 20 A U.S. (240 VAC, 20 A
international) is used on the phase conductors (all current-carrying conductors).
