Answer 1

NATO compliant
Exchange of tactical tracks, text messages, and imagery
Two channels of digital voice
TDMA based, secure, jam resistant, high speed digital data link
Operates in L band of UHF spectrum
127 usable nets

Question 2

What is located on the back of the MIDS Control Panel?

Answer 2

1 amp circuit breaker

Question 3

Function & location of the link-16 Audio Control Panel

Answer 3

Located @ TACCO

Powering on energizes TACCO ALT mode inhibit key line relay connecting TACCO J-Box directly to MIDS MT.

Question 4

Location & function of the ATAS

Answer 4

Located in B3
Runs the TacView software
TacView provides availability to overlay all Link-16, RADAR, and AIS
Contains two CPUs:
- Communication Management System= Ultra LinuxRT
- Tactical System Display Workstation= Windows 2000

Question 5

Location &function of the Switched Notch Filter Panel

Answer 5

Located in C1/C2
Prevents the transmission of Link-16 data into the IFF freq. range
Bus couplers on the panel provide communication between ATAS and MIDS MT

Question 6

Location & function of the MIDS MT

Answer 6

Located in C1/C2

• provides integrated position, navigation, identification, voice, and data communications
• TACAN antenna selection, TDMA up/down conversion, and receiver-synthesizer L-band RF channels

Question 7

Location & function of the Remote Power Supply (RPS)

Answer 7

Located adjacent to MIDS MT in C1/C2

Powers the MIDS MT and MIDS control panel

Question 8

What is the LOS range of Link-16?

Answer 8

300-500 miles

Question 9

The Fail 1 LED on the MIDS control panel will illuminate for how long during power up?

Answer 9

15 seconds

Question 10

Fail 1 LED indicates…

Answer 10

Failure in the MIDS MT or crypto batteries need to be replaced.

Question 11

Fail 2 LED indicates…

Answer 11

Failure within the RPS.

Question 12

The ATAS on switch does what?

Answer 12

Energizes the electromagnetic relay on the back of the ATAS mounting tray
This relay powers the ATAS and supplies a ground to Relay K1 on the Switched Notch Filter Panel

Question 13

What is the purpose the “Bus Reset” switch position?

Answer 13

Paces the MIDS MT in a dormant state

The MT will remain crypto variable but 1553 communications will be interrupted.

Question 14
