B.47 SYSTem:COMMunicate:LAN:TELnet:PORT? QUERY
SYST:COMM:LAN:TEL:PORT?
Syntax: Short Form: SYST:COMM:LAN:TEL:PORT?
Long Form: SYSTem:COMMunicate:LAN:TELnet:PORT?
Description: Indicates port assigned for Telnet communication via the LAN interface.
Return Format: in text format, a number from 0 to 65535
Example:
SYST:COMM:LAN:TEL:PORT? returns 8003 to indicate port 8083 is assigned to be used during
Telnet sessions.
B.48 SYSTem:ERRor? QUERY
SYST:ERR?
Syntax: Short Form: SYST:ERR? Long Form: SYSTem:ERRor?
Description: Returns error codes and messages.
Return Format: is text format in -XXX XXXXXXXXXXXXX
Example:
Input command S0URce:VOLTage 2w will cause error. SYSTem:ERR? returns error code “-138,”
and sending SYSTem:ERR? again returns no error code “+0,”. Refer to Table for a complete list of
error codes.
TABLE B-2. ERROR CODES
Error Code Explanation
0,“No error” No error
72, “OVP” Overvoltage protection error:
a. The output voltage is exceeding the OVP value.
b. The Analog Programming input for output voltage setting is too high (higher then
OVP value).
73, “OCP” Hardware overcurrent protection error: Output current exceeds 110% of rated current,
this OCP value is restricted by hardware and not adjustable.
74, “REMOTE SENSE OVER” The max. compensation voltage is 5V d-c (the sum of two wires, i.e. 2.5V d-c for each).
75, ““D2D Module 1 fault” The DC to DC converter module number 1 is failed. There is only one DC to DC mod-
ule in KLN 750W models.
76, ““D2D Module 2 fault” Not applicable
77, “Analog shut-off shutdown” a. The slave unit(s) failed when operate in parallel/series.
b. The Pin 23 and Pin 24 of the Analog Programming Port are shorted to shut-off the
output.
78, “Software OCP” Software over current protection error: The output current exceeds the set OCP value
(adjustable manually or remotely) for more than 1 second.
79, “AC Fault“ Ac line input abnormal
83, “FAN failed” One or more fan failed.
84, “D2D Module 3 fault” Not applicable
85, “D2D Module 4 fault” Not applicable
-102, “Syntax error” An unrecognized command or data type was encountered; for example, a string was
received when the device does not accept strings.
-104, “Data type error” The parser recognized a data element different than one allowed; for example, numeric
or string data was expected but block data was encountered.
-109, “Missing parameter” Fewer parameters were received than required for the header; for example, the
SYST:BEEP command requires one parameter, so SYST:BEEP is not allowed, while
SYST:BEEP ON is allowed.
-221, “Settings confect” Indicates that a legal program data element was parsed but could not be executed due
to the current device state
