7.10 RS485 Interface Kit (A-MP-CONV-SERIAL-xxx)

The RS232/485 interface provides a serial data transfer to the PC. However, the PC will have to be capable of
communicating at a sufficiently high baud rate. Most standard PC's communicate at speeds up to 115 kBaud which
is capable of communication with the linescanner at a scan speed of 36 Hz and at 256 pixel per scan data sampling
rate. For faster scan frequencies or for a higher pixel count the Ethernet connection should be used.
The RS485 Interface Kit comes with the following items:
•
RS232/485 converter
•
RS232 adapter 25 to 9-pin
•
RS485 cable rated at an maximal ambient temperature of 180°C (356°F) and in a length of 7.5 m / 25 ft
(A-MP-CONV-SERIAL-CB7) or 10 m / 33 ft (A-MP-CONV-SERIAL-CB10)
To use the RS232/485 connection, connect the linescanner to the PC with the RS485 cable. First, insert the 7-pin
DIN-round plug (IP65) into the socket on the back side of the linescanner, then tighten the locking cap carefully.
Next, connect the RS232/485 converter to the RS232 serial interface of the PC. Use the RS232 25 to 9-pin adapter
cable if needed. The RS232/485 converter is powered by the linescanner, and no separate power supply is
required.
