Description and Operation
TASK 25-63-50-870-801A01
1. Description and Operation
A. General
(1) Purpose
(a) The purpose of the CS144 Interface module is to combine the aircraft identification with the
aircraft position to generate the appropriate long message.
(b) The CS144 Interface module is designed to be connected between the ELT and the dongle
(that is part of the wiring to the RCP).
(c) The CS144 Interface module is compatible with all 3-Frequencies KANNAD 406 ELTs
except KANNAD 406 AS.
NOTE: 2-Frequencies KANNAD ELTs, KANNAD 406 AF-COMPACT, P/N S1840501-01,
KANNAD 406 AF-COMPACT (ER), P/N S1840501-04 and INTEGRA ELTs families P/N
S185X501-XX are not compatible with CS144 Interface module.
(d) Two versions are available:
1 CS144-RS connected to a NAV equipment by RS232, RS422 or RS485 link,
2 CS144-A connected to the NAV equipment of the aircraft via an ARINC 429 link.
(c) The CS144 Interface module is designed to be mounted on a mounting bracket 1 strap,
P/N S1820511-01.

B. Technical Data
(1) Overall dimensions:Refer to Figure 2
Figure 2 / 25-63-50-991-02
CS144, overall dimensions
(2) Weight
• Typical: 650 g. (1.433 lbs).
• Maximum: 700 g. (1.543 lbs).
(3) Environmental characteristics
• Operating temperature: -55 Degrees Celsius to +70 Degrees Celsius.
• Storage temperature: -55 Degrees Celsius to +85 Degrees Celsius.
• Magnetic effects: DO 160D / ED14D Section 15 Category Z.
• Induced signal susceptibility: not applicable, length less than 1.5 m.
• Radio frequency signal susceptibility: 20 V/m CW and SW.
(4) Compatibility list
• The CS144 is compatible with:
- All KANNAD 406 ELTs except SURVIVAL versions, KANNAD 406 AF-COMPACT,
KANNAD 406 AF-COMPACT (ER) and INTEGRA ELTs families P/N S185X501-XX .
- All remote control panels supplied by Orolia S.A.S. (RC1xx, RC200, RC300, RC400,
RC500, RC600, RC800, RC810).
- Programming dongles, Programming dongles A320 and A320 340, Programming
dongle ASSY
- Tested with the following GPS: HONEYWELL KLN90/KLN94, GARMIN GNS430/
GNS530, TRIMBLE TNL2101 I/O Approach Plus (CS144-RS),
- NMEA 0183 or ARNAV labels A/B (CS144-RS),
- ARINC 429 labels 310/311(CS144-A).
C. Operation
(1) The CS144 Interface module constantly computes a long message by combining the short
message (identification information available in the dongle) and the aircraft position available
from the NAV equipment installed on board the aircraft.
(2) Monitoring is done through a red LED:
(a) Permanently ON when the CS144 is ON and not faulty.
(b) Fast blinking if the CS144 Interface module is faulty.

D. Memory replacement
Replacement of the memory (See TASK 25-63-50-000-801A01, para D and TASK 25-63-50-400-
801A01, para B) is mandatory every 16000 flight hours or 10 years whichever comes first.
The manpower estimated time is 20 minutes.
Necessary parts to perform this task are available in an EEPROM replacement Kit, S1825515-01:
E. Upgrade
(1) CR12 replacement
Operation troubles have been identified with CS144 interface modules when connected to an ELT
with a new battery:
- the test of the ELT by RCP via CS144 may be faulty,
- the ON position of RCP may trigger a self-test on the ELT.
This is due to a battery with a high nominal voltage with regards to the clamping voltage of the CR12
protection: the CR12 protection (LCDA05) must be replaced by a protection with a higher clamping
voltage (LCDA12).
This replacement (See TASK 25-63-50-000-801A01, para E and TASK 25-63-50-400-801A01, para
C) should be performed if this failure occurs or during maintenance.
The manpower estimated time is 20 minutes
Necessary parts to perform this task are available in a CR12 replacement Kit, S1825515-02:

(a) R18 and pin 1 of CR12 (85),
(b) R18 and pin 2 of CR12 (85),
(c) R22 and pin 3 of CR12 (85),
(d) R22 and pin 4 of CR12 (85),
(e) the ground of PCB and pin 5, 6, 7 and 8 of CR12.

Check of CR12 connections
(2) Test of LRU (housing closed), Refer to Figure 1002.
With an ohmmeter, check that the resistor is less than 10 ohms between:
(a) J1-K (RCP ON) and J2-K (RCP ON),
(b) J1-A (RCP TEST/RESET) and J2-A (RCP TEST/RESET),
(c) J1-L (DONGLE GND) and J3-D (PWR GND).
