Writing to Registers
Writing to a volatile register is nearly instantaneous. Writing to a non-volatile
register, however, takes typically 16ms. Because the packet size can vary
based on the need for encoding, there are two possible packet structures.
The following tables show the byte sequences for writing a register in each
case.
Figure 41: Write Register Command, Value to be written is less than 128 (0x80)
The module will respond to this command with an ACK (0x06). If an ACK
is not received, the command should be resent. If a write is attempted to a
read-only or invalid register, the module will respond with a NAK (0x15).
Preliminary Draft
Figure 42: Write Register Command, Value to be written is greatre than or equal to 128 (0x80)
and remains powered for the duration of the register write. Loss of
important configuration information could occur if the unit loses power
during a non-volatile write cycle.
!
Warning:
Be sure that the module is properly powered

Reading from Registers
A register read command is constructed by placing an escape character
before the register number. The following table shows the byte sequence
for reading a register.
Figure 43: Read Register Command
The module will respond to this command by sending an ACK (0x06)
followed by the register number and register value. The register value is
sent unmodified. For example, if the register value is 0x83, 0x83 is returned
after the ACK (0x06). See table below for the format of the response. If the
register number is invalid, it will respond with a NACK (0x15).
