Notice!
If bit 4 SLEEP in the control byte is set to 1 and bit 2 D in the status byte has the value 1,
the BPS 8 is in SLEEP mode (laser and polygon wheel motor off). If bit 2 SLEEP in the con-
trol byte is set to 0, the BPS 8 returns to positioning mode after a boot time of approx. 5s. If
polling takes place while the BPS 8 boots and there is no valid position data yet, the error
message tape error (bit OUT) is generated.
Output of the diagnostic data
Example for diagnostic data: E05
Data byte 2 = E = 45 Hex = 01000101 Bin
Data byte 3 = 0 = 30 Hex = 00110000 Bin
Data byte 4 = 5 = 35 Hex = 00110101 Bin
Notice!
If there is a diagnostic query during SLEEP mode, SOS (S
ystem Operation Standby/
SLEEP) is transmitted in data bytes 2 to 4.
