USB connection
Evaluation Kit USB port may be used to connect OEM receiver with PC
USB port.
A standard USB 2.0 High Speed cable with USB type A Male connector
on one side and USB type B Male connector on other side (not included
in the Kit) may be used to connect OEM receiver with PC through J116
USB type B Female connector on Evaluation Kit board.
A standard USB 2.0 High Speed cable with USB type A Male connector
on one side and USB type Mini-B Male connector on other side (not in-
cluded in the Kit) may be used to connect OEM receiver with PC through
J115 USB type Mini-AB Female connector on Evaluation Kit board.
For best results, we recommend to use as short as possible (from 0.5
to 3 meters) USB high quality cables with marking similar to this: “USB
SHIELDED 28AWG/1P + 24AWG/2C HIGH-SPEED USB 2.0”. USB connec-
tion cannot be used to connect two OEM receivers together directly for
data exchange. This is because OEM receiver has “device” type of USB
port, that may be connected only to “host” type of USB port, usually
present on PC or on USB hubs.
Warning:
Because both J116 USB type B and J115 USB type Mini-AB Female connec-
tors are physically connected to one and the same USB port, only one USB cable at a
time may be used. Do not connect to Evaluation Kit two USB cables simultaneously.
Ethernet connection
The J119 “ETHERNET” port may be used to:
- connect OEM receiver with Local Area Network (LAN);
- connect OEM receiver with PC directly;
- connect two OEM receivers together directly.
For Ethernet connection we recommend to use short (from 1 to 10 me-
ters) high quality UTP 5 or 5e category cable with two RJ45 Male con-
nectors on both ends.
RJ45 Male connector external view and pinout shown below:

For direct connection between two OEM receivers or between one OEM
receiver and PC, the Ethernet Crossover cable usually used. Crossover
cable should be wired according to the wiring table below
