JA34-001 Universal Radio Adapter
SECTION 1 - DESCRIPTION
1.1 System Overview
The JA34-001 Universal Radio Adapter allows the aircraft audio management system access to a non-aviation radio.
The JA34-001 provides fully isolated audio signal paths to and from the radio to allow a noise-free installation.
Microphone biasing and artificial sidetone generation are selectable for radios without them.
The JA34-001 is setup on a 'per installation' basis using cable CAB-USB-0002 and the JA99-001 Configuration Cable,
or cable CAB-USB-0006, and downloading the system configuration settings from a PC into non-volatile control
devices.
1.2 Features Overview
The JA34-001 unit features an industry standard D-Sub connector pin-out to allow easy field upgrades.
All internal settings are quickly adjusted using the proprietary ProCS™ (Product Configuration Software).
Two Configuration ports are provided for configuration loading; one is beside the main connector and one is on the
back of the unit.
All audio outputs are balanced.
The JA34-001 provides relay contact keying, artificial sidetone generation and microphone voltage biasing.
1.3 Inputs and Outputs
Refer to the JA34-001 connector map for the mating connector designators and contact assignments for the
input and output signals.

SECTION 2 – INSTALLATION
2.1 Introduction
This section contains unpacking and inspection procedures, installation information, and post-installation checks.
2.2 Continued Airworthiness
Maintenance of the JA34-001 is on condition only. Scheduled inspection and/or periodic maintenance of this unit is
not required.
2.3 Unpacking and Inspecting Equipment
Unpack the equipment carefully. Check for shipping damage and report any problems to the relevant carrier. Confirm
that the Certificate of Conformance is included. Complete the on-line warranty card from the Jupiter Avionics
Corporation (JAC) website – www.jupiteravionics.com.
2.3.1 Warranty
This product manufactured by JAC is warranted to be free of defects in workmanship or performance for 2 years from
the date of installation by an approved JAC dealer or agency. This warranty covers the cost of all materials and labour
to repair or replace the unit, but does not include the cost of transporting the defective unit to and from JAC or its
designated warranty repair centre, or of removing and replacing the defective unit in the aircraft. This warranty does
not cover failures due to abuse, misuse, accident, or unauthorized alteration or repairs.
THIS WARRANTY IS VOID IF THE PRODUCT IS NOT INSTALLED BY AN AUTHORIZED JAC DEALER. If the on-
line warranty card is not completed, the product will be warranted from the date of manufacture.
Contact JAC for return authorization, and for any questions regarding this warranty and how it applies to your unit(s).
JAC is the final arbiter concerning warranty issues.
2.4 Installation Procedures
WARNING: Loud noise can cause hearing damage. Set the headset volume to minimum before
conducting tests, and slowly increase the volume to a comfortable listening level.
CAUTION: The power input circuitry of the unit may be damaged if the installation does not conform
to the wiring instructions in this manual.
2.4.1 Cabling and Wiring
All wire shall be selected in accordance with the original aircraft manufacturer’s maintenance instructions, or AC43.13-
1B Change 1, Paragraphs 11-76 through 11-78. Unshielded wire types shall qualify to MIL-W-22759 as specified in
AC43.13-1B Change 1, Paragraphs 11-85, 11-86, and listed in Table 11-11. For shielded wire applications, use Tefzel
MIL-C-27500 shielded wire with tag ring or equivalent (for shield terminations) to make the most compact and easily
terminated interconnect. Follow the Connector Map in Appendix A of this manual.
Allow 3” from the end of the shielded wiring to the shield termination to allow the connector hood to be easily installed.
Refer to the Interconnect drawing in Appendix A of this manual for shield termination details. Note that this unit has a
‘clamshell’ hood that is installed after the wiring is complete.
Maintain wire segregation and route wiring in accordance with the original aircraft manufacturer’s maintenance
instructions.

JA34-001 Universal Radio Adapter
Installation Manual
Rev A Page 5
Unless otherwise noted, all wiring shall be a minimum of 24 AWG, except power and ground lines, which shall be a
minimum of 22 AWG. Refer to the Interconnect drawing for additional specifications. Check that the ground
connection is clean and well secured, and that it shares no path with any electrically noisy aircraft accessories such
as blowers, turn-and-bank instruments, or similar loads.
2.4.2 Mechanical Installation
The JA34-001 can be mounted in any attitude and location with adequate space and sufficient clearance for the
connector and wiring harness. It requires no direct cooling.
2.4.3 Post Installation Checks
2.4.3.1 Voltage/Resistance checks.
Do not attach this unit until the following conditions are met:
a) Check P1 pin 1 for +28 Vdc power.
b) Check P1 pin 14 (Power Ground) for continuity to ground (less than 0.5 Ω).
c) Check P1 pin 15 (Chassis Ground) for continuity to ground (less than 0.5 Ω).
d) Check P1 pins 8, 20,21 and 23 (Output Ground) for continuity to ground (less than 0.5 Ω).
e) Check all pins for shorts to ground or adjacent pins.
2.4.3.2 Configuration
Ensure that the JA34-001 contains the correct configuration settings. This may be done at the factory, on the
maintenance bench or in the aircraft before the power on checks are performed. Refer to section 2.5.
2.4.3.3 Power on Checks.
Power up the aircraft’s systems and confirm normal operation of all functions of the JA34-001 (see section 2.4.5).
a) Begin with only the pilot’s headset attached. Confirm radio operation for both receive and transmit. Check the
radio selection and inputs. Do not proceed until the radios are functioning correctly.
b) Unusual buzzes, hums or other background audio are symptomatic of multiple grounds, or noisy external
systems such as blowers or pumps sharing wiring with the audio system. If a transmitter fails to key or
correctly modulate it is often the result of not connecting all required grounds to the radio or external audio
system.
c) Check that all configurations settings are correct.
When all performance checks are satisfied, complete the necessary regulatory documentation before releasing the
aircraft for service. Refer to Appendix B.
2.5 System Operation
The JA34-001 is a remote mount unit and has no user accessible controls.
2.5.1 Configuration Operation
The JA34-001 accepts commands on the Configuration connector via the configuration cable (JA99-001) and the
configuration tool (ProCs™). (See section 2.6 Adjustments and Configuration)
2.5.2 Receive Operation
The RECEIVE INPUT is level controlled and summed with the MIC INPUT (Sidetone) and routed to the RECEIVE
OUTPUT.
2.5.3 Sidetone Operation
The MIC INPUT audio is level controlled and summed with the Receive Audio and routed to the RECEIVE OUTPUT.

Rev A Page 6
2.5.4 Relay Operation
The RELAY KEY INPUT selects the connection of both of the relay common contacts to either their normally closed
contact or their normally open contact.
2.5.5 Microphone Operation
The MIC INPUT audio is level controlled and routed to the MIC OUTPUT.
2.6 Adjustments and Configuration using ProCS™
The JA34-001 has no internal mechanical adjustments. Configuration data is sent to the JA34-001 via the
programming port input, using the ProCS™ configuration tool and configuration cables (JA99-001 and CAB-USB-
0002, or CAB-USB-0006).
For full information on the configuration process, and for installation of ProCS™ on your computer, refer to the
ProCS™ manual on the Jupiter Avionics website.
2.6.1 ProCS™ Setup
The JA34-001 menu items 'ProCS Setup' provide Setup drawings showing the cabling arrangement for
connecting the JA34-001 to a computer to allow configuration using ProCS™.
2.6.2 Configurable Settings
A standard unit is shipped from the factory with all internal adjustments configured to the default levels shown in bold
on the JA34-001 Settings page. At installation, it may be desirable to change some of these settings to suit the local
operating environment.
The Aircraft Audio Selection and Non-Aircraft Radio Selection choices are made from drop-down boxes as shown. For
further information, refer to sections 2.6.3.1 and 2.6.3.3. All input, output, MIC bias information etc. is automatically
added to suit the selected radios.
2.6.3 JA34-001 Settings
The Settings window is divided into three sections: the Aircraft Audio System; the Universal Radio Adapter; and the
Non-Aircraft Radio. Each section is colour-coded to keep the relevant information together.
The required radios can be selected
from the dropdown boxes at the top of
the 'Aircraft Audio System' and 'Non-
Aircraft Radio' sections.
New radios may be added (see
sections 2.6.4 and 2.6.5 below).
