V.4 RJ CONNECTOR
LAN-Transformer RJ45 10/100/1000 BaseT
Only available with RJ version
It allows connecting a classical Ethernet cable (cat 5e or cat 6 for 1000
BaseT)
V.5 P-ETH
HE10/HE13/HE14/Strip Male Header 2.54mm pitch, 2x5 pins
Only available with TTL version
- Compatible with HE10/HE13/HE14 Female Receptacle
(ex: SAMTEC Series BCS, BSW, ESQ, ESW...
ANTELEC Series APC104, FT2... )
This connector gives directly raw signals from the Ethernet PHY
component, without insulation. The PHY used on the WLn-LINK-OEM-
TTL is 88E1118 from Marvell.
These signals can be used to relocate a RJ45 Plug far away in your
system. The signals should be correctly insulated, routed with wires of
equal lengths and with a 100ohms differential impedance, especially
with long distance. You can see at the next page some examples of
insulation for these signals
You can also connected two PHY together by using two transformers
(using two times "Example 1", for each PHY)

Page 15 / 26
DTUS066 rev A1 March 21, 2012
Example 1 : with Transformer and RJ separated
Example 2 : with Transformer included in RJ

V.6 P-USER
Receptacle connector 0.5mm pitch DF12-20DS-0.5V from HIROSE
- Compatible with Header HIROSE Series DF12
(ex : DF12(5.0)-20DP-0.5V(86)
DF12B(5.0)-20DP-0.5V(86)
DF12D(5.0)-20DP-0.5V(81)
DF12E(5.0)-20DP-0.5V(81) )
- Using this connector requires a height of 5mm between WLn-
LINK-OEM and your motherboard (see chapter "MOUNTING OF THE
DEVICE" for more information)
- This connector is not needed for common use of the WLn-LINK-
OEM. It only provides some additional functions.
I²C and UART1 should be only used with ACKSYS authorization.
Their incorrect use could irremediably corrupt the product and
void all pertaining guaranty.

Example of wiring for UART (1 and/or 2) :
The CKEY is an optional storage device
used to save and restore the product
configuration. You can relocate it
somewhere else in your system. It
should be removed and inserted only
when power supply source is OFF.
CKEY functionality is currently not
implemented and shouldn't be used.
It will be available soon !
The relevant CKEY model for WLn-
LINK-OEM range is CKEY-M2.

V.7 ANTENNA CONNECTOR
With normal version : 3 x U.FL male connectors, from Hirose
With /3 version : 3 x MMCX male connectors
- Connect it three 2.4/5GHz antennas with 50ohms coaxial cable
(with U.FL or MMCX female connector according to radio card)
- You should use 3 antennas at the same time, else performance
will be drop.
WARNING: Leaving an antenna connector unplugged may
damage the miniPCI radio module of /3 version.
V.8 P-ADM
This connector, present on the board, is not documented voluntarily
and shouldn't be used.

VI MOUNTING OF THE DEVICE
VI.1 Not using P-USER
Usually, when not using signals from P-USER, you can plug the WLn-
LINK-OEM at the height you want (minimum of 5mm), with the
previously indicated connectors .
> 5mm

Page 20 / 26
DTUS066 rev A1 March 21, 2012
VI.2 Using P-USER
If you need P-USER, you should mandatorily mount WLn-LINK-OEM
at the height of 5mm.
To do this, you must use special connectors for P-GEN, P-LED and P-
ETH, that will be bottom mounted, with bottom entry.

SAMTEC BCS-1xx-L-D-PE-BE
ANTELEC Series FT2 )
