This command will not remove the Hold state. Note that only capital „F‟ is

recognized.

? – Handshake Signal Status

The status of SSN and DRDY lines are returned to the user in a single byte. The

value of the byte indicates the status of these lines, as given in Table 5-3.

Table 5-3: Handshake Signal Status

! – Pulse CLEAR Signal

On receiving this command a 10 s pulse is generated on the CLEAR pin. This pin is

normally LOW.

$ – SSN Control

Issuing this command sets or resets the CommBoard‟s SSN line. The syntax is:

where # must be “0” or “1”. The SSN pin will be set LOW if the number following

the „$‟ character is “0” and will be set HIGH if the number is “1”.

Example: x$0!wn113r~1rsi<CR>

This sentence asserts SSN LOW and writes “113” (decimal), then waits for

DRDY to go high, after which it reads a 16-bit signed integer. SSN is still LOW

at the end of the sentence.

. – Pause 2 ms

Sending a “.” command causes a 2 ms delay before processing the next character in

the receive buffer. This is useful when working with the V2Xe.

V or v – CPHA Setting

The SPI clock phase can be set by the user. “V” sets CPHA=1, “v” sets CPHA=0.

The default is “v”, CPHA = 0.

O or o – CPOL Setting

The SPI clock polarity can be set by the user. “O” sets CPOL=1, “o” sets CPOL=0.

The default is “o”, CPOL = 0.
