7.2.4 Baud Rate Setting
Seven optional rates are possible: 1200, 2400, 4800, 9600, 19200, 38400, 57600.
1. Press REM button. The REM LED illuminates. ”IN t ” message appears on the Voltage display.
2. Rotate Voltage encoder until Voltage display shows ”bd”.
3. Press Voltage encoder. Voltage display shows ”bd” and Current display shows baud rate.
3. Rotate the Current encoder to select required baud rate.
4. Press Current encoder to enter selected parameter to memory.
5. When parameter is accepted the display blinks once and returns to the previous level.
7.2.5 Language Selection (RS232/RS485, USB)
The Z
+
implements SCPI standard command line interface to remotely control the power supply.
Additionally, a small subset of legacy GEN commands has been provided for ease of use and
backwards compatibility.
1 Press REM button. The REM LED illuminates. ”IN t ” message appears on the Voltage display.
2. Rotate Voltage encoder until Voltage display shows ”ANG”.
3. Press Voltage encoder. Voltage display shows ”ANG” and Current display shows language.
3. Rotate the Current encoder to select required language.
4. Press Current encoder to enter selected parameter to memory.
5. When parameter is accepted the display blinks once and returns to the previous level.
7.2.6 Setting Unit in Remote, Local Lockout or Local Mode
Local mode:
When the power supply is in local mode, it can receive queries. If a query is received, the power
supply will reply and remain in Local mode. Serial commands may be sent to set and read the
status registers while the unit is in Local mode. If the Enable registers are set the power supply
will transmit SRQ’s while in Local mode.
Remote mode:
If a command is received that affects the output or a Remote command is received, the power
supply will perform the command and change to Remote mode.
When the power supply is in Remote mode, REM LED illuminates and parameters cannot be
changed via the front panel. Return to Local mode by pressing the front panel REM Button or via
serial port command.
Local Lockout mode:
When the power supply is in Local Lockout mode, REM LED illuminates and parameters cannot
be changed via the front panel. It is possible to return to Remote mode, only with a serial port
command or by AC power recycle.
