Code Command Detail
command strings are fully sent with less than 5 seconds between
each character.]
Ed<termination> Buffer full error Too many characters contained between the Start Character and
the Carriage Return of a command. Message is not processed by
the probe kit. [Host should send correct string.]
Ee<termination> Invalid command
first character
The received command is not a valid command per the command
list for the probe kit. Specifically, the first character of the
command is not one of the valid first characters of any acceptable
command. [Host to check command]
Ef<termination> Invalid command
additional
character(s)
The additional parameters contained in a received command are
not valid. Specifically the additional characters, after the first
character in a command, are not valid additional characters for this
type of command for the probe kit. [Host to check command.]
Eg<termination> Probe hardware
error
An error has been detected by limited error detection in the probe
(not the interface) and it has been determined that this error will
cause the requested response to be unreliable, so the requested
response is not sent. [Host should try the command again to see if
this probe error clears. If error does not clear probe needs to be
repaired. Note that since the probe is not user repairable, there is
no reason for further fault detection in the probe.]
Eh<termination> Laser not on error Commands cannot be sent to or received from the probe without
the laser power on. [Turn laser on from front panel and check for
fault status.]
3.7.2 GPIB (IEEE-488) Operating Protocols
3.7.2.1 IEEE-488 (GPIB) Communications
For IEEE-488 operation, the device address is set using the dip switches on the rear panel of the product.
Ensure that each device connected to the IEEE-488 buss is set to a unique address. (Resetting the address
requires re-booting the unit).
Specific IEEE-488 bus commands depend on which software package you are using. To send commands be
sure that the Field Monitors address is set properly and that the controller has correctly identified the unit as a
“listening” device.
When sending commands to the unit via the GPIB interface, the command must be terminated with an EOI .
3.7.2.2 Setting the IEEE-488 (GPIB) Address
The IEEE-488 device address can be set to any number between 1 and 30. This selection is made by setting
Switches 1 to 5 of the rear panel DIP switch to the binary equivalent of the number. Table 3-4 illustrates this
switch selection. Please note that although addresses 0 and 31 can be entered, neither address is valid for this
device, and therefore should be avoided.
