The Tally Tab
This contains the payloads for the Tally and the
Tally Reply.
For information on the Format Characters buttons
see the section on the Data Tab.
The SPI card sends a Request to the device it is
connected to obtain the current status of the
device. A RequestReply is then sent from the
device to the SPI card in response to the Request.
A Tally is initiated by the device and sent to the SPI
card. If for example the device is a VCR and the
play button is pressed on it, then the device will
send a Tally to the SPI card (indicating that it is
now playing). The TallyReply is sent from the SPI
card to the device in response to the Tally.
Request Poll Time is the time (in milliseconds)
between each Request payload being sent.
The Preset Tab
This contains the value, which the command will
be set to upon pressing the preset button on the
SPI card.
Note that this only applies for Number & String
styles.
