Command Description

LS

Loads a record from the serial flash memory, in order to retrieve the
list of recorder signals.

RC

Defines which of mapped signals should be recorded.

RG

Recorder gap: specifies sampling rate of the recorder.

RL Recorder

length.

RP[N]

Recorder parameters: defines which event will trigger the recorder,
and the trigger position. Also defines basic time quantum for
recorder (TS or four times TS) and data to be uploaded to host by
next BH command.

RR

Launches recorder and reads back its status.

RV

Signal mapping: maps the IDs of the recordable signals to logical
IDs that the recorder can reference.

SR

Status register, which indicates the status of the recorder: idle,
armed, triggered and recording, or ready with data.

TS

Sampling time, the basic resolution of recorder.

WI[21]

Actual amount of recorded data.

Table 10-1: Commands Relevant to the Recorder

10.1.1

Recorder Sequencing: Programming,

Launching and Uploading Data

In order to activate the recorder, it must first be programmed to indicate which signals
should be recorded, at what resolution and what will trigger the recording event. A
number of limitations apply to programming the recorder:

The recorder cannot be programmed while it is armed or recording. It must

first be stopped, or “killed” (RR=-0).

Modifying the recorder programming invalidates any previously recorded

data. Be sure to upload all data that you need before programming the
recorder.

After it is programmed, the recorder can be launched by:

RR=1

Arms recorder to trigger at next start of motion.

RR=2

Starts recording immediately.

RR=3

Arms recorder to start recording at next trigger event.

To poll the status of the recorder, use the RR and SR commands. After the recorder
data is ready, use the BH command to upload the data.
