In most cases, power supply with 12 VDC, 1 Amp sta-
bilized output will be good enough for Evaluation Kit
powering.
Serial RS-232 connection
A standard Null-Modem cable (not included in the Kit)
with DE-9 Female connectors on both ends and with
length from 1 to 10 meters may be used to connect PC
COM_X port with Serial A, Serial B or Serial C port, D
port on Evaluation Kit as well as to provide connection
between two Evaluation Kits to send some data from
one OEM receiver to another OEM receiver.
DE-9 Female connector external view and pinout is
shown on the picture below.

Serial RS-422 connection
Serial RS-422 port may be used to connect OEM receiv-
er with other external devices as well as connect two
OEM receivers together for some data exchange be-
tween them.
A Null-Modem RS-422 cable (not included in the Kit)
with DE-9 Female connectors on both ends and with
length from 1 to 100 meters may be used to connect
two OEM receivers together. The DE-9 Female connec-
tor external view and pinout shown in Figure 2-4.
For best results, we recommend to use high quality STP
5 or 5e category cable type as well as specialized for
RS-422 applications cable types, for example: Belden
9730, 9830 or similar.
The Serial RS-422 Null-Modem cable should be wired
according to the wiring table below.
