The DEPOLOX 3 plus is not able to send data directly to a printer.
3.7.2 Description of the RS485 Bus Interface
The serial RS485 bus interface of the DEPOLOX 3 plus , built-in as a
standard, is used for data transmission to a PC, to an external plant control
or to the MF485 interface card (e.g., for connection to a printer).
The serial RS485 bus interface of the DEPOLOX 3 plus is designed as a
symmetrical two-wires bus line to EIA RS 485 (DIN 66259 part 4 resp.
ISO 8482), that enables data transfer with high transfer rate (19.2 KBaud)
and long distances (up to 1200 m).
Characteristics:
• Data transfer in both directions
• twin wire connection (half duplex)
• Bus structure (addressable interface, up to 32 bus users)
