There is a possibility to control and monitor the controller via a PC over a serial interface
(USB or RS-232). In control, measure and automatic modes a cyclic output of the current
instrument status can be switched on and off. The output interval is 1 second.
7.1 USB interface
The PC provides a virtual COM port over the USB interface. The control of the instrument
is therefore no different from the control via the RS-232.
7.2 RS-232 Interface
To connect, the RxD, TxD and GND lines are required. The connection is made with an
in-line serial cable (1:1, male/female).
7.3 Interface configuration
Press the MENU button and press the
/
button until the SETTINGS submenu
item appears and confirm with SELECT. In the submenu, go to the item RS-232/USB
with the
/
button and confirm with SELECT. The following settings can be made:
■

(USB, RS-232)
