4.1The RS232/422/485 Interface Option
With this option installed, the circuits for both the RS232 and RS422/485 interfaces are provided as standard. They can be used to interface to both printers and computers. A number of standard printer protocols are built into the instrument.
4.1.1Hardware
The following diagram provides an overview of the RS232/RS422/RS485 communications hardware. All three interfaces are available on the rear terminal strips and the user can select either one by making the appropriate connections.
The RS232 interface is primarily used with printers or for simple communication with a computer over a short distance. The RS422 and RS485 interfaces are used for communication over a long distance or in applications requiring multipoint communication.
