APPENDIX B: KISTLER-MORSE ® PROTOCOL SERIAL COMMANDS
‘wZ’ Command — Write DSP Filter Qualify
This command is sent by the master to set the DSP Filter qualify of an STXplus. The range of
acceptable values is 2-20. For this example, the master sets the DSP Filter qualify for an STXplus
at address 01 to 15(%). Any of the 5 leading zeros may be omitted.

‘[R1’ Command — Read 20mA Trim Value
This command is sent by the master to request the STXplus to send the 20mA trim value. The
trim value is used to calibrate the current output engine at the 20mA point. The range of
acceptable values is 0-65535. The default value is 59,674. For this example, the master requests
the 20mA trim value for an STXplus at address 01 which returns 59611 and a checksum of 66.

‘[R2’ Command — Read 4mA Trim Value
This command is sent by the master to request the STXplus to send the 4mA trim value. The trim
value is used to calibrate the current output engine at the 4mA point. The range of acceptable
values is 0-65535. The default value is 11912. For this example, the master requests the 4mA
trim value for an STXplus at address 01 which returns 19611 and a checksum of 62.
