Interface control
For remote control, the corresponding interface (CAN, RS-232, USB, IEEE-488, Ethernet) has to be
selected first in Menu “F07 Set Interfce”. The device switches to REMOTE state when receiving the
first command from the selected interface. The yellow LED “REMOTE” is lighting. The yellow LEDs
VOLTAGE and CURRENT stop lighting to indicate that no local control is possible at the moment.
By pressing the LOCAL button the remote control is suspended. The device can now be controlled
via front panel. When receiving new commands via Interface, the device switches back to REMOTE
state.
If the device is in “HV-ON” state via interface, high voltage can be turned off by pressing the ON/OFF
button. In this case the device goes to LOCAL state as well.
Exception:
If local control is disabled (Local Lockout, see chapter 6.3), the device can only
be turned off via mains switch POWER!
While receiving or transmitting data via RS-232 or IEEE-488, the LED’s RxD (Receiving) or TxD
(Transmitting) are flashing.
5.1 CAN Interface
Attention:
Turn off the device with mains switch POWER before connecting/disconnecting
the interface cable.
The CAN interface is located at a male D-SUB-9 connector at the device rear. The pin assignment is
as follows:
Pin
Signal
2
CAN_L
(CAN Low)
3
CAN_GND
(CAN Ground)
5
CAN_SHLD (CAN Shield)
7
CAN_H
(CAN High)
For the CAN protocol, please see the description of the EDCP protocol in the manual
CAN-Interface
Multi-Channel High Voltage Power Supply Module
EHS xxx and EDS xxx
Thus, the device can be controlled with the program isegCANHVControl or with the iseg OPC server.
