General Description
The R. L. Drake model EH244 encoder host is a
platform for supporting modular MPEG2 and H.264
video encoders, including the SDE24, HDE24, and
SDI24. The encoder host multiplexes the encoder
outputs into up to 4 output channels, configurable
via a front panel interface or ethernet web server.
The encoder includes provisions for emergency alert
services, using either video replacement or SCTE18
Installation and Mounting
Slot Numbers:
The EH244 is designed to be installed in a standard
19'' rack. All encoder and interface modules must
be installed in the EH244 chassis before power is
applied. DO NOT INSERT ENCODER MODULES
WHILE THE UNIT IS POWERED. Doing so will
void the EH244 and encoder warranties.
The input modules on the rear of the chassis are
numbered 1-6, from left to right, if you look at the rear
of the unit. Each encoder's program number will be
assigned based on its slot location (slot 1 will provide
programs 1 and 2; slot 2 will provide programs 3 and
4; etc). HDE24 and SDI24 encoders only provide
odd-numbered programs, as each of these encoders
is a single-input encoder.
If the EH244 will be used in an EAS-enabled sys-
tem, and the unit will be used as the master EAS unit
in Slot 6 or Slot 6 + SCTE 18 modes, a Drake
model SDE24EAS input module must be installed in
slot 6 of the chassis. If the EH244 is configured for
slave EAS modes Slot 6 or Slot 6 + SCTE 18,
a Drake model ASII module must be installed in slot
6, and wired to the ASI Output port of the previous
EH24/EH244 in the chain.

control messages.
The EH244 accepts up to 6 encoder modules, and al-
lows each encoder's output program to be assigned
to any or all 4 output program streams. The EH244
can output on up to 4 frequency-adjacent QAM chan-
nels using an internal QAM modulator, and supports
optional ASI outputs that mirror the QAM program
streams.

If the EH244 will be used as a master in a DTA-
enabled system, a Drake model ASII input module
must be installed in slot 6 (or slot 5, if the unit is an
EAS master using the Slot 6 or Slot 6 + SCTE
18 EAS modes). This ASII must be connected to
the output of a PC that is generating the DTA con-
trol messages, created by the R. L. Drake DTA Con-
trol software. If the EH244 will be used as a slave
in a DTA-enabled system, a Drake model ASII input
module must be installed in slot 6, and connected
to the previous EH24/EH244 ASI Output. For slave
systems using both DTA- and EAS-modes, a single
ASII input module will perform both functions.
Connect the AC line cord to an appropriate
120-240V, 50/60Hz AC power source. The EH244
will always be powered and running as long as it is
connected to its power source.
Connect the RF output to a 75-ohm cable system.
Optionally, connect the EAS terminals to the output
of an EAS receiver to enable emergency alerts. Con-
nect the ethernet control interface port to a secured
network or VPN for remote system configuration.
