UNIT CONFIGURATION
The unit will automatically detect the new inserted interface.
The interface icon will be shown in the display, see fig 5 - 4.
For programming the voltage, current and/or power via the
interface, set the correct source for CV, CC and CP
respectively, see below example:
o
For example the interface is mounted in slot2.
To program the CV-settings via this interface, via the front
menu go to CONFIGURATION -> PRG SOURCE ->
Vsettings and set it to Slot2.
To program the CC-settings via this interface, go to
CONFIGURATION -> PRG SOURCE -> Isettings and also
set it to Slot2.
To program the CP-settings via this interface, go to
CONFIGURATION -> PRG SOURCE -> Psettings and also
set it to Slot2.
Instead of doing this via the Front Menu, the source can
also be set via the web interface or via Ethernet commands
if the unit is connected to the network via LAN.

SERIAL PROGRAMMING
The unit can be programmed by using the serial programming
commands. See table 5.1 for an overview of the available
commands.
To start, first the command "CH n" must be executed to
activate the interface by setting its channel number (address).
The variable n is a number between 1...32.
For example "CH 1".
The command "CH?" queries the channel of the active serial
interface.
For more details about the commands in table 5.1, refer to
chapter 5 of the
Programming manual for Ethernet &
The manual is stored inside every SM15K unit and can be
downloaded via the web interface. It can also be downloaded
from
5.7
PROGRAMMING SPEED
Programming from a low to a high output voltage is nearly
load independent.
5.8
MONITORING VIA SERIAL INTERFACE
Via the programming command "MEASURE:" the voltage,
current or power can be monitored.

for details.
5.9
TROUBLE SHOOTING
Check the programming source is set to the correct slot.
Check the output is switched ON, the Interlock is connected
and Remote ShutDown is low.
The first programming command must be "CH n" otherwise
the
interface will not be activated.
Check that the communication is working; "*IDN?" must return
a value. Ensure to end the query with the termination
character LF.
(LF = 0x0Ah in ASCII)
Note: the serial interface uses the '.' (dot) as the decimal
symbol and not the ',' (comma). Check if your program is
using the settings in Microsoft Windows© regional settings.
Either change your program to specifically use the '.' or else
change the decimal symbol to '.' in your regional settings
(from the control panel).
Check that the power supply's output is not limited.
Consult the SM15K manual about adjusting the limit settings.
Check that ALL values for CV, CC and CP are not zero.
