conversion number and desired parameter will not correspond. Thus the weight and the conversion number
should be included in a single transmission or a 'create row' command for a database. The A/D conversion
number is not a displayable parameter. This means that it cannot be displayed from weigh mode with the
use of the select key (i.e. pressing 63 [SELECT] or pressing 63.[#] [SELECT]).
SETUP MODES
Parameter 63 can be selected as a parameter for use with analog outputs (P172 → P175), input interpreters
(P222), database (P701 → P799), custom transmits (P1000), setpoints (P5114, P5115, P5134, P5135,
P5150), and as a parameter for Modbus (P6001 → P6247). When selecting this parameter #A/D is shown if
the scale is not known yet. When the scale is known (the instance) then #A/Dx is displayed where x is the
number of the scale.
A/D CONVERSION NUMBER WITH %O
You can get the value of a scale's A/D conversion number by using =63.xP%o where x represents the
number of the scale for which the current A/D conversion number is desired.
You can set the state of a scale's A/D conversion number by using 63.xP=$%o where x represents the
number of the scale for which the current A/D conversion number is desired and $ represents the number
you wish to set the A/D conversion number to. Remember this exact number may not be seen unless you
read the A/D conversion number immediately after setting it.
USING WITH CUSTOM TRANSMITS
The A/D conversion number parameter was created primarily for use with custom transmits (P1000). The
same custom transmit must contain 63P and the desired parameters for which the corresponding A/D
conversion number is desired. To send a continuous transmit at high rates (60 Hz maximum) the baud rate
(P200) must be fast enough, the scale filter settings at P116 must be fast enough and the amount of data
sent by the custom transmit must be limited. Finally, P980, TxRate only allows multiples of 0.1 second. To
change the transmit rate to alternate multiples the I%Q macro must be used. This rate will be reset to the
value at P980 on power up and when exiting setup mode!
Example
To send a continuous transmit every 30th of a second out comm port 1, first set the filter at P116 for the
scale you are interested in to 1.0 second. Set P998 (Continuous Transmit) to "enabled" and configure the
custom transmit table as desired (use 63P). After saving and exiting setup mode or after powering up, send
a .033I%Q to override the interval at P980. Note that setpoints, macros, and use of other comm ports will
affect the transmission rate.

The Data Storage Device (DSD) parameters are associated only with the DSD feature. DSD must be
enabled at P590 and configured at P591 → P595 in order to use these parameters.
