Minimal settings required for easy configuration:

• for the RS232 slave service port (terminals 6, 7, 8)

- baud rate (1200...38400 baud)

- number of characters + parity + stop bits (8N1, 8E1, 8O1, 8N2)

• for the RS485 master side port (terminals 4 and 5) and RS485 master front port (terminals 10, 11, 12)

- baud rate (1200...19200 baud) (dip switches SW1)

Up to 64 instruments with different addresses can be connected by means of the two RS485 master ports.
