b). Resend ( FE )

Preliminary

a). Any time EM84530 receives an invalid command, it returns a Resend command to the system.

b). When EM84530 receives a Resend command, it retransmits its last packet of data. If the last packet was

a Resend command, it transmits the packet just prior to the Resend command.

c). In stream mode, if a Resend command is received by EM84530 immediately following a 3-byte data

packet transmission to the system.

c). Set Default ( F6 )

The command reinitializes all conditions to the power-on defaults.

d). Disable ( F5 )

This command is used in the stream mode to stop transmissions from EM84530.

e). Enable ( F4 )

Begins transmissions, if in stream mode.

f). Set Sampling Rate ( F3,XX )

In the stream mode, this command sets the sampling rate to the value indicated by byte hex XX,

shown in following:

g). Read Device Type ( F2 )

EM84530 always echoes “ FA,00 “ following this command.

h). Set Remote Mode ( F0 )

Data value are reported only in response to a Read Data command.

i). Set Wrap Mode ( EE )

Wrap mode remains until Reset ( FF ) or Reset Wrap Mode ( EC ) is received.

j). Reset Wrap Mode ( EC )

EM84530 returns to the previous mode of operation after receiving this command.

k). Read Data ( EB )

This command is executed in either remote or stream mode. The data is transmitted even if there has been

no movement since the last report or the button status is unchanged. Following a Read Data command,

the registers are cleared after a data transmission.

l). Set Stream Mode ( EA )

This command sets EM84530 in stream mode.
