1.0 ASTi Interface-Tango (AI-Tango)
The AI-Tango is a compact I/O distribution device that connects local or remote control pan-
els and other peripherals to the network via Ethernet. The ASTi server or another host trans-
mits I/O data to the AI-Tango over a local area network (LAN). Depending on the user's or
program's needs, the AI-Tango can connect to simulated radio panels and press-to-talk (PTT)
devices.
Figure 1, "AI-Tango hardware diagram" below shows an example of an AI-Tango network
configuration:

4.0 Dimensions
The AI-Tango has two bezels, encompassing the front and rear panels. The AI-Tango is Con-
formitè Europèene (CE)/Restriction of Hazardous Substances (RoHS) certified. Removing the
bezels voids the CE certification.
Caution: This equipment is not suitable for use in locations where children are likely to be
present.

6.0 Analog inputs
Figure 9, "Analog input circuitry" below shows the AI-Tango's analog input circuitry.
Figure 9: Analog input circuitry
This section provides several examples illustrating how you might use the AI-Tango's analog
inputs:
lAnalog input for a toggle switch
lAnalog input for resistance
6.1 Analog input for a toggle switch
To use the analog input with a toggle switch, simply connect the switch to the analog input
and ground pins, as the example below illustrates:

AI-Tango Technical User Guide (Rev. A, Ver. 2)

6.2 Analog input for resistance
In this example, insert a resistance between the analog input and analog input ground pins.
The four-channel selector knob contains a switch that changes the resistance between the ana-
log input and analog input ground pins, as shown below:

7.0 Digital output
The digital output circuitry consists of an opto-isolated, solid-state relay for switching power
to external loads. Table 2, "Digital output rating and dissipation" below summarizes the AI-
Tango's digital output opto-isolated field effect transistor (FET) values:
Type Opto-isolated FET
Maximum continuous current rating 120 mA
Maximum power dissipation 300 mW

8.0 Status indicator lights
The LED status indicator light displays the AI-Tango's status:
Figure 13: AI-Tango status indicator lights
Table 3, "AI-Tango status indicator lights" below defines each status indicator light for the
AI-Tango:
LEDLight Status
White solid This light indicates the AI-Tango's default “Power On” state. If solid white
displays for over two minutes, remove power, count to 10, and reapply
power, or contact [email protected].
Yellow solid The AI-Tango has booted and is awaiting configuration.
Yellow flashing The AI-Tango is updating. Do not turn off the device.
Red solid Hardware Error #1: failed to find device; remove power, count to 10, and
reapply power, or contact [email protected].
Red flashing Network Error: the AI-Tango cannot send packets to the destination
address.
Purple flashing Find Me is enabled. This feature can identify an AI-Tango.
Blue solid The AI-Tango is sending status packets to its destination address but is not
receiving status packets.
Green flashing The AI-Tango is sending and receiving status packets to and from its des-
tination address.
Note: The AI-Tango can receive from any address, not just its configured
destination.
Off Firmware Error #2: remove and reapply power, or contact support@asti-
usa.com.

10.0 Rackmount
The available rackmounting bracket accommodates two AI-Tangos side by side and measures
1U high and 19" wide. To rackmount the AI-Tango, follow these steps:
1. Remove the two bottom corner screws on the front of the AI-Tango.
2. Use a nut driver (3/16") to remove the two jackscrews from each side of the four con-
nectors.
3. Remove the faceplate with the white lettering and the bezel. Save the bezel for when
you remove the AI-Tango from the rackmount.
4. Place the AI-Tango into the backside of the rackmount. The rackmount fits in place of
the bezel.
5. Place the faceplate on the front side of the rackmount
6. Install the jackscrews on each side of the four connectors.
Figure 14: AI-Tango rackmount installation
Note: The included rackmount kits are compatible with a variety of ASTi distribution
devices (e.g., ACU2s, AI-Tangos). As a result, you can mount different device types next to
each other in the same rack. Go to the original manufacturer's documentation for more
information about rackmount installation.
