3.18 Odometer Input
The BL51E supports:

Input voltage:
- 5 V DC to 50.4 V DC

Pulse counter frequency:
- 2 kHz max.
The pulse counter value is read inside the FPGA in the BL51E by IP core
16Z082_IMPULSE.
3.18.1 Front Connection
Table 46. Connector types – 6-pin PCB plug
Table 47. Pin assignment – BIN IN 2 (6-pin PCB plug)
Table 48. Signal mnemonics – odometer input
The odometer input switching levels are software-configurable via SMBus by enabling/
disabling pull-up and pull-down resistors:
