what is a group of 4 bits called?
black box group
data is transmitted in units of 4 bits (1 nibble) for which the interval between two falling edges (single edge) of the modulated signal with a constant amplitude voltage is evaluated. a sent message is 32 bits long (8 nibbles) and consists of the following components: 24 bits of signal data (6 nibbles) that represents 2 measurement channels of 3 nibbles each (such as pressure and temperature), 4 bits (1 nibble) for crc error detection, and 4 bits (1 nibble) of status/communication information. optionally, data can be transferred in 20 bit messages (5 nibbles) composed of a single 12 bit (3 nibble) measurement, a 4 bit (1 nibble) crc error checksum, and a 4 bit (1 nibble) status/communication field.
sent (protocol)
bits 17a–51a encode the time of the following minute in binary-coded decimal, most significant bit first. beginning with bit 17a comes 4 bits of tens of years, 4 bits of years, 1 bit of tens of months, 4 bits of months, 2 bits of tens of days, 4 bits of days, 3 bits of day of week (0=sunday), 2 bits of tens of hours, 4 bits of hours, 3 bits of tens of minutes, and 4 bits of minutes.
