Command Format
All commands and responses are ASCII strings.
“A～Z” characters are reconized as command strings. “＋,－,．,0～9” characters are reconized as parameters.
Command Group Sending
Multiple commands can be sent in a single string by seperating commands with “,”.
＜Ex.＞A1,MV10.00,MC2.00,OT1
However, a single string with multiple commands assigning addresses will error.
＜Ex.＞A1,OT1,A2,OT1 /* Errored due to multiple address assignment commands */
Alarm Response Trigger Factors
In the event that any of the following error conditions are met, the ZX power supply will promptly return an
alarm response ”ALM128”.
If an error is generated while inputing commands, recovery will not occur until delimiter is received.
To prevent this, make certain to send either “CR, LF, or CR+LF” when an alarm response is received.
・
When undefined command is received
・
When command parameters exceed the range
・
When a character or symbol other than numerals 0～9, ＋, －, and decimal point is sent in parameters
・
When sent with a single parameter containing more than 2 decimal points
・
When sent with spaces between the command and parameter
＜Ex.＞MV_35
Space
・
When a command is sent in lowercase
＜Ex.＞mv35
・
When a string received at one time (until delimiter is received) exceeds 128 characters
Setting examples that are not errors
・
Throw away digits in parameters which exceed the maximum number of numerical places
＜Ex.＞MV10.999 → MV10.99
For ZX-S Series power supplies, if either OVP, OCP or OHP error is generated the alarm response will change
to “ALM160”. During device errors, only “LV”, “LC, “AR”, “TP”, and “TK” commands are valid. All other
commands will return alarm responses.
Delimiter
Please add a end character (delimiter) to the end of commands being sent to a ZX power supply.
Possible delimiters that can be used are listed below.
・CR Carriage Return
・LF Line Feed
・CR+LF
Use any of the above as a delimiter.
