Ieee 802.3 (Ethernet) - Optional; Characteristics Of Interface - Fluke Norma 4000 User Manual

Hardware Handshake
With a hardware handshake, the instrument signals readiness for reception via the lines
DTR and RTS. A logic 0 identifies "ready," a logic 1 identifies "not ready."
Whether or not the controller is ready for reception is signalled to the instrument via the
CTS or the DSR line (see section, "Signal Lines"). The transmitter of the instrument is
switched on by a logic 0 and off by a logic 1. The RTS line remains active as long as the
serial interface is active. The DTR line controls the instrument's readiness for reception.
Wiring between Instrument and Controller
Wiring between the instrument and the controller is an extension cable (in case of a 9 pin
controller connector), that is, the data, control, and signalling lines have straight-through
wiring. The wiring diagram shown in Figure 3-3 applies to controllers with a 9-pin or 25-
pin connector.

IEEE 802.3 (Ethernet) – Optional
The instrument is optionally equipped with IEEE 802.3 (Ethernet) interface. The
connector to Ethernet interface (RJ-45) is provided at the rear of the instrument (see
Figure 3-4). A controller for remote control can be connected via the interface.
Connection is made using a twisted pair cable.
