40 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

#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.

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

New unit becomes effective after power is
cycled or a reset command is executed.

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
