Interface parameters
The controller CVC 2000
II
is equipped with a serial interface at the rear side of the housing (RS 232C,
nine-pole Sub-D-plug).
☞ Respectively plug-into or remove the cable (cable RS 232C, nine-pole Sub-D) from the interface only if
the equipment is switched off.
☞ The interface is not electrically isolated from the measuring circuit.
☞ For optimal electromagnetic compatibility assemble an interface filter (cat. no.: 63 82 35).
The controller can be operated via serial interface. Measuring results, preselections and the status of the
controller can be read out at any time. Controlling via interface (write commands) is only possible, if the
remote operation mode has been preselected at the controller. During remote operation (”PC” is
displayed) the controller can be operated only via interface, the keys at the controller have no
function.
Setting of the interface
The setting of the interface parameters directly at the controller is described below. The factory set values
are underlined.
➨ 1200, 2400, 4800 or 9600 BAUD
➨ 7 data bits odd, 7 data bits even, 8 data bits none, 8 data bits odd, 8 data bits even
➨ no Handshake, XON/XOFF Handshake, CTS/RTS Handshake
➨ remote on, remote off
☞ Unchangeable: Startbit = 1, Stopbit = 1
Keep key ▲ pressed while switching on.
☞ The controller switches to the mode to configurate the inter-
face.
BAUD-Rate is displayed.
➨ Press key ▲ or ▼ to select the BAUD rate and confirm with
key START/STOP (”96”=9600, ”48”=4800, ”24”=2400,
”12”=1200).
Data bits are displayed.
➨ Press key ▲ or ▼ to select the data bits and confirm with
key START/STOP.
Parity is displayed.
➨ Press key ▲ or ▼ to select parity and confirm with key
START/STOP (”no” = no check of parity, ”O” = odd, ”E” =
even).
Handshake is displayed.
➨ Press key ▲ or ▼ to select handshake and confirm with key
SART/STOP (”no” = no Handshake, ”HA” = RTS/CTS, ”SO”
= XON/XOFF).
Remote is displayed.
➨ Press key ▲ or ▼ to select parity and confirm with key
START/STOP (”no” = local operation, ”On” = remote opera-
tion).
☞ The controller switches to normal operation mode (process
control not active).
