PC or terminal connection
Via the serial interface, you can configure the scan engine by means of a PC or terminal. For this, you need
a RS 232 connection that establishes the RxD, TxD and GND connections between PC and scan engine.
The RS 232 connection can be established in the following ways:
• Direct connection of the plug connector of the scan engine to the PC or terminal via its own connector.
• Connection via a MA-CR modular adapter unit
To simplify the connection of the connection wires to the PC interface, a modular adapter unit (MA-CR)
is available for implementing the 6-pin plug connector to D-SUB, 9-pin (see chapter 13.2 "Acces-
sories").

Cable lengths and shielding
The maximum cable length is 3 m.
Should a cable extension be necessary, make certain that the cables of the RS 232 interface are shielded.
