5.2 Connection to the PC

Connect the First DPA to the PC's RS232 serial port, using a 9-pin female plug connected to the RS232 socket on

the rear panel of unit.

Connect RS485 IN of the Second DPA to the First DPA 's RS485 OUT socket, in this way, you can connect up to 32 DPA units for a same PC.

IMPORTANT!!!

If the first unit is placed at a distance to the PC that exceeds 5 meters, RS232 to RS485 converters must

be used to reach it. And the first unit connected to the PC thru RS232 must be switched ON and working, otherwise none of the other units can be controlled by the PC.
