Note: By pressing ENTER it is possible
a) to change from 1 Volt to 0 Volt (if output of 1 Volt is active)
b) to stop the calibration sequence (if output of 0 Volt is active)
If the above described functions do not operate properly, the SDM needs to be
repaired. Refer to
section 4.2.4 "SDM specific troubleshooting"
to further evaluate the
problem.
3.2.13 Serial Data Port (RS-232)
For a detailed description of the Serial Data Port (RS-232) refer to the corresponding
section of the
Technical Manual for the SDM
. The Serial Data Port is located on the
rear panel of the SDM (
see
Figure 2 Rear Panel of the SDM
).
To verify the data transmission to an external device (e.g. PC) activate the protocol
"SenTecLink" (proceed as described in the
Technical Manual for the SDM)
.
Connect one end of a serial cable to the serial data port (RS-232) of the SDM and
connect the other end of the cable to a serial port of your PC. If your computer has no
serial port but USB-ports an USB232 Converter Cable can be used.
Start V-STATS software on your PC. Select the appropriate COM-port in the Sub-menu
"Communication / Settings … "). Start the sub-menu “Communication / with SDM (via
Serial Interface) …”, this opens dialog “Communication with SDM (via Serial Interface)”
with the “Connection Status” indicator showing the status of the communication
between V-STATS™ and the SDM (for detail description see
V-STATS
Instruction
Manual
).
Verify that data transmission between V-STATS™ and the SDM works properly. The
“Connection Status” indicator lights green if the connection is established and the
communication is successful between V-STATS™ and SDM.
If the above described functions do not operate properly, the SDM needs to be
repaired. Refer to
section 4.2.4 "SDM specific troubleshooting"
to further evaluate the
problem.
3.2.14 LAN Test
In order to test correct LAN communication the following steps need to be
performed:
You will need a network environment to plug in your PC running a registered
V-STATS™ and the SDM. Alternatively you may use a crossover LAN cable and
connect the PC and SDM. Attach PC and SDM to the network.
Note: Please consult the online help of V-STATS™ for further information.
Configure the SDM and connect the SDM to the PC via serial cable .
Run V-STATS™ (latest version) and open the dialog-window “Communication with
SDM (via Serial Interface)…” by clicking on the respective big button in the center
main window or on the icon in the upper menu-bar of the graphic window or by
using the menu “Communication / with SDM (via Serial Interface) …”
