Single and Multi- Point Addressing | RF-Link Technology NL6000

Single and Multi- Point
Addressing	An NL6000 can be configured to transmit to a single unit,
	a group of units, or to broadcast to all units within range.
Acknowledgement	The NL6000 can be configured to request an
	acknowledgement (ACK) from the destination modem
	with each transmission. If it does not receive an ACK,
	the unit can retransmit a specified number of times.
Auto-Transmit	The NL6000 will automatically trigger transmission of data
	over the RF link: The NL6000 will wait for characters to
	arrive via the serial port in order to completely fill a
	packet size as defined under Network/Max Packet Size
	before transmitting. The typical default setting for TX
	CHAR TIMEOUT is 100 and MAX PACKET SIZE is 300.
	This will give you a reasonable response time between
	serial data arrival and transmitting data. The MAX
	PACKET SIZE should be set based on your applications
	typical maximum packet size.
Configuration Templates	The NL6000 software allows you to save a configuration
	as a template and download the parameters in that
	template to other units that share the same configuration.
	This saves time when configuring a large network. Care
	should be taken in maintaining the Diagnostics
	configuration settings. These settings are normally
	factory set using radio test equipment and are unique to
	each NL6000 radio
