KLN Series 022014 B-11B.56 SYSTem:COMMunicate:LAN:SMAS? QUERY SYST:COMM:LAN:SMAS?Syntax: Short Form: SYST:COMM:LAN:SMAS?Long Form: SYSTem:COMMunicate:LAN:SMAS?Description: Indicates Subnet Mask address assigned for communication via the LAN interface.Return Format: is text in the format xxx.xxx.xxx.xxxExample: SYST:COMM:LAN:IP? returns 255.255.0.0 to indicate the Subnet Mask address is set to255.255.0.0.B.57 SYSTem:COMMunicate:LAN:TELnet:PORT COMMAND SYST:COMM:LAN:TEL:PORTSyntax: Short Form: SYST:COMM:LAN:TEL:PORT Long Form: SYSTem:COMMunicate:LAN:TELnet:PORT Description: Assigns port to be used for Telnet communication via the LAN interface. KLN units use port5025 for Telnet sessions. Changing this address requires that power to the KLN be cycled off, thenon.Argument: in text format, a number from 0 to 65535Example: SYST:COMM:LAN:TEL:PORT 5025 assigns port 5025 to be used during Telnet sessions. A Telnetsession can typically be started from a host computer shell by sending the IP address followed bythe port number, e.g., telnet 192.168.0.100 5025.B.58 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 65535Example: SYST:COMM:LAN:TEL:PORT? returns 5025 to indicate port 5025 is assigned to be used duringTelnet sessions.B.59 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 XXXXXXXXXXXXXExample: 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 oferror codes.TABLE B-2. ERROR CODESError Code Explanation0,“No error” No error72, “OVP” Overvoltage protection error:a. The output voltage exceeds the OVP value.b. The Analog Programming input for output voltage setting is too high (higher thanOVP value).73, “OCP” Output current exceeds 110% of rated current, this OCP value is restricted by hardwareand 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” DC to DC converter module number 1 failed (only one module in 750W models).76, ““D2D Module 2 fault” DC to DC converter module number 2 failed (two modules in 1500W models).77, “Analog shut-off shutdown” a. The slave unit(s) failed when operating in parallel/series.b. Pins 23 and Pin 24 of Analog Programming Port are shorted to shut-off the output.
