Physical Installation
The ACS 2010 is designed to be Dzus mounted and should be installed in the aircraft using the DC37SL-F
Installation kit that is included. The above outline drawing of the unit with dimensions will facilitate the
installation.
The connector pin configuration of the ACS 2010 rear connector and the recommended wire size for the
aircraft cable harness is shown on the following page. Be sure that adequate clearance is allowed for the
rear connector and cable harness.

Interface Schematic
■ Connector Pin-out
The ACS 2010 wiring harness should be constructed of Tefzel aircraft wire (M22759/16 grade). Power and
ground wires should be 18 or 20 AWG, and all other wires may be 22 AWG. Shielded wires should be used
where noted. Adequate protection against wear and chafing should be taken by using a braided cable sleeving
or jacket. Before completing installation, verify that all cable connector pins are seated properly and that the
connector is securely mounted to the unit mating connector.
Pre-fabricated cable harnesses are available from Air Comm to expedite installation — consult our sales
department for details.

Front Panel Controls
( See Figure 1 — Page 8 lor pictorial)
■ 1 - Norm - Emer Switch
This switch controls the operations of the audio panel in the event of an audio amplifier failure. In the “up"
position (NORM) the audio panel is in normal operating mode. In the “down" position (EMER) all audios are
summed and then fed directly to the headphones. This enables the use of the transmitters and other
equipment during audio amplifier failure.
- 2 - QUICK ADJUST Adjustable Receive Audio Volume - On/Off Pots
Any Receive audio can be selected and muted using innovative new QUICK ADJUST volume pots. A
receive audio is selected by pulling out the knob toward the operator. With the receive audio activated, the
headphone volume of the audio can then be adjusted to the desired level. Turning the knob in a clockwise
direction increases the volume level, and turning in the counter-clockwise direction decreases the volume
level. To mute the receive audio, the knob only needs to be pushed back in. The volume for that audio
remains set at the desired level and does not need to be reset the next time it is selected.
■ 3 - ICS Volume Control
This knob adjusts ICS headphone volume. Clockwise rotation increases the volume - counter clockwise
rotation decreases the volume.
■ 4 - Lighting
The audio panel is lit by two 28V lamps ( P/N 327 ) which provide night time visibility for all panel legends.
These lamps can be replaced in the event of a failure by unscrewing the front panel mounted filter cap,
inserting a new lamp, and reinserting the filter into the front panel.

■ 5- Mic Selector
This rotary switch performs three functions simultaneously. It (a) connects the mic to the selected
transmitter (b) selects the associated keyline, and (c) selects the associated audio (if not already selected
using the audio select-mute volume pot).
■ 6-Transmit Indicator
When the transmit key is activated this indicator lights up to show that the audio panel is in the transmit
■ 7-ICS Switch
This switch selects the ICS mode. In the “up" position the audio panel is connected to the common ICS
buss. This enables the audio panel to communicate with any other audio panels also connected to the
common ICS buss. In the “center" position (OFF) the audio panel is disconnected from all other panels.
In the “down" position ( HOT ICS ) the headphone mic becomes active and its signal is fed into the ICS buss
without having to depress the ICS key switch. This provides for “ hands-off" ICS operation.
