SpeakerCraft SmartPath AT-1.0 Installation Instructions

SmartPath ™
AT-1.0
Amplified Terminator

INSTALLATION INSTRUCTIONS

The AT-1.0 provides a convenient means of interconnecting
SpeakerCraft (and industry compatible) IR products in IR repeating
systems. It includes a wide bandwidth amplifier for robust operation.
It has blaster drive power capability and is reverse voltage protected.

FEATURE DESCRIPTIONS (Refer to Fig. 1)
1. Spring-loaded EZ-Connect Terminals accept wire sizes 14 to 28
AWG for connection of the following:
• +12V DC – Powers connected IR Receivers, Keypads, etc.
• GND – Return for Power, IR signal and Status indicators
• ST OUT – Connects status voltage to Status Indicators in
IR Receivers, Keypads, etc.
• IR IN – Receives IR control signals from IR Receivers,
Keypads, etc.
2. Mounting Holes – Attaches the AT-1.0 to any flat surface using
the two screws provided.
3. EMITTERS – Two 3.5mm jacks drive two emitters at medium
power.
4. EMITTERS/BLASTERS – Two 3.5mm jacks drive two emitters at
medium power or two blasters at very high power.
5. DIP Switch (3 position) – The upper two positions switch between
emitter power (EM ON) and blaster power (BL ON) for the two corre-
sponding EMITTERS/BLASTERS jacks.
CAUTION: The BL ON position sets the AT-1.0 to very high blaster
power. Be sure to return the DIP switch to Emitter On (EM ON)
position when driving normal emitters. Failure to do so will
smoke the emitters!
Network Terminator. The bottom DIP position allows the IR IN and
IR RCVR inputs to be terminated with a 500Ω resistor (NET ON), or
un-terminated (NET OFF). The NET ON position should be chosen
when using long lengths of wire (over 50', shielded in particular)
between the IR receiver, keypad, etc. and the AT-1.0. This ensures
best operation for high data rate IR codes. If using two or more
AT-1.0' s in a paralleled network system (see Fig. 4), be sure only
ONE of the AT-1.0 Terminators is set to the NET ON position.

6. 12V DC REGULATED – 2.1mm jack, center pin +, accepts 12V DC
regulated power supplies to power the IR system. Calculate the current
required, then use SpeakerCraft power supplies PS-1.0 (200 mA) or PS-2.0
(1.2 A). Note: The "no signal" current draw of the AT-1.0 is zero.

7. STATUS IN 5-24V DC - 2.1mm jack, center pin +, accepts 5V through
24V DC power supplies to power system ON/OFF Status Indicators of
connected IR receivers, keypads, etc.

8. IR RCVR – Exclusive four-circuit 3.5mm jack provides connection for
SpeakerCraft direct plug-in IR Receivers. Connections are made, not only
for Power, Signal and Ground, but for the Status Indicator in the IR
Receivers as well.

SYSTEM CONNECTIONS
The following are a few typical applications of the AT-1.0 for IR repeater
systems.

1. Plug in the IR Receiver and Emitters as shown.
Note: Since the AT-1.0 employs emitter current sharing, you may use
any of the IRE-1.0, 2.0, 3.0, or 4.0 SpeakerCraft emitters in any
combination you wish.
2. Set the DIP switches to EM ON and NET ON or NET OFF .
3. Plug in the Power Supply.
4. The AT-1.0 system should now control the components.
A Multi-Room System
Fig. 3 is an example of a multi-room (not multi-zone) system. SpeakerCraft IR
receivers in each room, plus a local IR receiver, control the various compo-
nents in the main room or equipment area.
