tina03e1-b (2004-02) BPG400 v1.om
The following table lists all permissible commands of the RS485 host and the cor-
responding responses of a BPG400 SR during data transfer.
Depending on the operation mode selected (BPG or RIG mode) the BPG400-SR
responses may differ. Syntax errors will produce an error message.
For each command listed, a programming example is given in the last column
where:
T:
Command data transmitted by the host
R:
Data received by the host (from BPG400-SR), in BPG and RIG mode
R
BPG
:
Data received by the host (from BPG400-SR), only in BPG mode
R
RIG
:
Data received by the host (from BPG400-SR), only in RIG mode

Programming example and remarks
Read pressure
measured value
#aaRD CR
*aa_x.xxEsyy CR
→ BPG mode
T: #02RD CR
R: *02_5.36E–04 CR
R
RIG
: *02_9.99E+09 CR
If gauge is switched off and during the first 3
seconds after gauge is switched on.
Read status
#aaRS CR
*aa_status CR
→ BPG mode
T: #02RS CR
R
BPG
: *02_BPG_ST_5 CR
R
RIG
: *02_00_ST_OK CR
Set address (offset)
#aaSAoo CR
*aa_PROGM_OK CR
→ BPG mode
T: #02A3_CR
R *02_PROGM_OK CR
New address becomes effective after power is
cycled or a reset command is executed.
If the user sets the offset address to a value so
that the operating device address would be
>0x3F
Hex
, the offset address is set to "0" by the
device itself.
Set pressure unit
#aaSUunit CR
*aa_PROGM_OK CR
Error message
T: #02SUPASCAL CR
R
BPG
: *02_PROGM_OK CR
New unit becomes effective after power is
cycled or a reset command is executed.
R
RIG
: ?02_SYNTX_ER CR
Read pressure unit
#aaRU CR
*aa_unit CR
Error message
T: #02RU CR
R
BPG
: *02_PASCAL CR
R
RIG
: ?02_SYNTX_ER CR
Set filament
#aaSFn CR
For future use
*aa_PROGM_OK CR
T: #02SF2 CR
R: *02_PROGM_OK CR
Set overpressure
#aaSOx.xxEsyy CR
For future use
*aa_PROGM_OK CR
T: #02SO5.00E–02 CR
R: *02_PROGM_OK CR
Set degas off
#aaDG0 CR
*aa_PROGM_OK CR
→ BPG mode
T: #02DG0 CR
R: *02_PROGM_OK CR
Set degas on
#aaDG1 CR
*aa_PROGM_OK CR
→ BPG mode
T: #02DG1 CR
R: *02_PROGM_OK CR
When the gauge is switched off, a degas on
command will produce an error message:
R: ?02_COMM_ERR CR
If pressure is >7.20E–06 mbar, the degas on
command is disabled
Read emission
#aaSES CR
*aa_xxFA_EM CR
→ BPG mode
T: #02SES CR
R: *02_
_20MA_EM CR
Read version
#aaVER CR
*aa_VERv.vv CR
→ BPG mode
T: #02VER CR
R: *02_VER_1.04 CR
