PD (Pull Up/Down Direction)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
The resistor pull direction bit field (1 = pull-up, 0 = pull-down) for corresponding I/O lines that are set
by the PR command.
See PR (Pull-up/Down Resistor Enable) for the bit mappings.
Parameter range
0x0 - 0xFF
Default
0xFF
IU (I/O Output Enable)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
The IU command disables or enables I/O UART output. When enabled (IU = 1), received I/O line data
packets are sent out the UART. The data is sent using an API frame regardless of the current AP
parameter value.
Parameter range
0 - 1

IT (Samples before TX)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
Sets or displays the number of samples to collect before transmitting data. The maximum number of
samples is dependent on the number of enabled I/O lines and the maximum payload available.
If IT is set to a number too big to fit in the maximum payload, it is reduced such that it will fit. A query
of IT after setting it reports the actual number of samples in a packet.
Parameter range
0x1 - 0xFF
Default
1
IS (Force Sample)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
