DESCRIPTION
The User Status (
U
) command is used to return information about various conditions of the unit, and may be sent
at any time without interfering with normal operation. The following text provides more detailed information about
the
User Status (
U
) command responses.
*
U0
: Query and clear the Event Status Register (
ESR
). This request responds with
an integer
nnn
of the form
000
≤≤≤≤
nnn
≤≤≤≤
255
, where the individual values are as follows, and multiple
values are summed:
128
- Power On (Bit 7)
008
- Device Dependent Error (Bit 3)
064
- Buffer 75% Full (Bit 6)
004
- Query Error (Bit 2)
032
- Command Error (Bit 5)
002
- Stop Event (Bit 1)
016
- Execution Error (Bit 4)
001
- Acquisition Complete (Bit 0)
*
U1
: Query the Status Byte Register (
STB
). This request responds with an integer
nnn
of the form
000
≤≤≤≤
nnn
≤≤≤≤
255
, where the individual values are as follows, and multiple values are summed:
128
- Buffer Overrun (Bit 7)
008
- Scan Available (Bit 3)
064
- RQS or MSS (Bit 6)
004
- Ready (Bit 2)
032
- Event Detected (Bit 5)
002
- Triggered (Bit 1)
016
- Message Available (Bit 4)
001
- Alarm (Bit 0)
*
U2
: Query and clear the Calibration Status Register (
CSR
). This request
responds with an integer
nnn
of the form
000
≤≤≤≤
nnn
≤≤≤≤
255
, where the separate values are as follows,
and multiple values are summed. The
CSR
Bits 7 and 6 respond with the following combined values:
192
- Calibration Mode, Command Active
(Both Bits 7 and 6)
064
- EEPROM Test Mode (Bit 6 only)
(Not discussed in this manual.)
128
- Calibration Mode, Idle (Bit 7 only)
000
- Normal Run Mode (Neither Bit 7 nor 6)
Meanwhile, the
CSR
Bits 5 through 0 respond with the following individual values:
If in Normal Run Mode (
000
), then: If in either Calibration Modes (
192
or
128
), then:
032
- Read Failure (Bit 5)
032
- Read Failure – EEPROM Error (Bit 5)
016
- Write Failure (Bit 4)
016
- Write Failure – EEPROM Error (Bit 4)
008
- Checksum Error (Bit 3)
008
- Checksum Error – EEPROM Error (Bit 3)
004
- NV-RAM Error (Bit 2)
004
- Calibration Error (Bit 2)
002
- Invalid Password (Bit 1)
002
- Invalid Password (Bit 1)
001
- Invalid Command (Bit 0)
