In some cases, to connect other external devices with
Evaluation Kit RS-422 port, not Null-modem, but
Straight Through RS-422 cable may be used.
The Serial RS-422 Straight Through cable should be
wired according to the wiring table below.

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 con-
nector 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 included 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 pos-
sible (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 connection can-
not be used to connect two OEM receivers together di-
rectly 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 connectors 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 meters) high quality UTP 5 or 5e category
cable with two RJ45 Male connectors on both ends.
RJ45 Male connector external view and pinout shown
below:
Figure 5.
RJ45 Male connector
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
Table: 5.
