I/O cable
Airbus Defence and Space does not provide any kind of I/O cables. The system integrator must make the cables
according to the needs of the applications.
All customer-specific I/O pins are 5 V logic level compatible. The pinout is given in Section I/O lines on page 32. The
maximum load for a single I/O line is 20 mA. Note that the total I/O load should be limited to 160 mA (all I/O pins
combined).
• Recommended cable suppliers: Carol Cable, Dearborn, Belden, Alpha, West Penn Wire. A multi-wire cable is
recommended, the cable size depends on the chosen connector (may vary from AWG20 to AWG28).
• Connector suppliers: Tyco Electronics, Conec, Amphenol, Molex.
Data cable
The Airbus Defence and Space data cable CA-123 consists of a matching board-to-wire connector and a keyed RJ-
45 connector for the DLR-3T cable. For custom-made cables, Airbus Defence and Space recommends to use the
following suppliers:

TETRA RF cable
The connector of the TDM880i board is a 50
impedance-matching MMBX (Huber+Suhner 82_MMBX-S50-0-1/
111_N). For custom-made cables, use a 50
low-loss cable with a matching connector. Use a proper cable size for
the connector selected.
An optional accessory (CA-126) is available in Airbus Defence and Space to convert from a MMBX to a TNC
(female).
GPS RF cable
The connector of the TDM880i board is a 50
impedance-matching IPX connector (female) (Hirose U.FL-R-SMT-
1(10).
For custom-made cables, use a 50
low-loss cable with a matching connector. Use a proper cable size for the
connector selected, for example RG58C/U, RCG316U or RG142B/U.
An optional accessory (CA-127) is available in Airbus Defence and Space to convert from a IPX to a SMA (female).
Installation procedure
It is recommended that the parameter and network configuration of the radio is done before its installation.
Installing the TDM880i
1. Check and clean the surface the radio module is to be installed on. Also make sure that the mechanics is suitable
for the radio module. If you are uncertain what the installation procedure is or if the mechanics selected can be
used with the radio module, consult the retail dealer.
The components on the TDM880i board are not mechnically protected. Therefore, ensure that the board does
not come into contact with any external equipment, cables or surfaces when mounted to avoid damaging the
TDM880i or causing short circuits.
Always ensure that there is sufficiently space around the heatsink for ventilation, and that the enclosure, if any, is
sufficiently cooled and/or ventilated. In certain conditions and usage forced air-cooling may be necessary.
2. Check that you have the tools and mounting screws that are suitable for the material the radio is to be installed
on, and the accessories needed for the installation and operation of the TDM880i.
3. Remove the radio from the package and dispose the packing materials according to the local instructions.
WARNING:
Remember that the radio module is ESD sensitive.
