CL4490 User’s Manual
4.2.2 CN4490 Settings
The CN4490 Settings Page is shown below, as it will appear the first time when the CN4490
check box is checked.
4.2.2.1 CN4490 Settings
Client/Server: Designates CN4490 type. In each network, there must be only one Server. All
other CN4490 units must be programmed as Clients. The number of Clients in the network is not
limited; however, if performance diminishes, consider additional RF Networks.
Channel Number: A number that designates an independent network of CN4490 units. Up to
32 independent networks can be created. The valid range of values for this field is 16 to 47.
Max Transmit Retries (For Clients and Servers in Point-to-Point networks only): This value
represents the maximum number of times a particular data packet will be transmitted
unsuccessfully, or without an acknowledgement, before the CN4490 discards the packet. The
default value is 16 attempts. If communication is lost and the Client’s Link LED is on, try
increasing this value in small increments until communication is reestablished.
Note: This value is always associated to Client radios and Server radios in Point to Point Mode.
The valid range of values for this field is 2 to 255.
