5.1 Preparation for configuring using the DLOAD10 program
Connecting the computer to the controller
To make the connection, use the USB-RS converter offered by SATEL. The controller has no
RS port connector, therefore you must use the PIN3/RX adapter, which is delivered with the
converter. Screw the adapter wires to the controller terminals in accordance with Table 1 and
Fig. 2.

Notes:
If you cannot establish communication between the controller and the program, add
a 47 k
Ω
resistor between the LV and +12V terminals.
Before connecting the adapter wires to the AL and LV terminals, disconnect other wires
from these terminals.
