XTend™ RF Module ‐ Product Manual v2.x6x
Polling Base Configuration:
Polling Remote Configuration:
Set the MD (RF Mode) parameter (MD = 3).
Set MY (Source Address) parameter (MY = 0).
Set the sequential range of Polling Addresses using the PB (Polling Begin Address) and PE
(Polling End Address) parameters.
(Optional) Enable Acknowledged Reliable Delivery (RR >= 0). Note: Basic Reliable Delivery is
also supported. Refer to the ‘Polling Mode - Basic section for more information.
(Optional) Use the PD (Minimum Polling Delay) command to configure a delay between polls to
slow down system (if needed).
(Optional) Enable API Mode to address remotes within polling range on a packet-by-packet
basis.
Set the MD (RF Mode) parameter (MD = 4).
Configure sequential source addresses for all remote modules using the MY (Source Address)
command.
Set the DT (Destination Address) parameter to point to ‘Polling Base’ (DT = 0x0000).
(Optional) Enable Acknowledged Reliable Delivery (RR >= 0). Note: Basic Reliable Delivery is
also supported. Refer to the ‘Polling Mode - Basic section for more information.
