RF Neulink NL6000 User Guide 17 If a reliable path does not exis t between a remote unit and a bas e station, you can confi gure one or more NL6000 units as a repeater to reach the hidden unit. The repeater can work with both sim ple x and half duplex networks.
RF Neulink NL6000 User Guide 18 Figure 8 shows the use of a wildcard (12 FF) to transmit data to multiple units within range of Unit #1 that have a MY ID start ing with 12 Figure 8: Addressing with Wildcards Figure 9 shows the use of a w ildc ard (FFFF) to broadcast data to all units within range of Unit #1.
RF Neulink NL6000 User Guide 19 Consider the following example of a repeater (MY ID30 00) configured to repeat pack et s transmitted from a base statio n (MY I D2000) to a hidden remote (M YID420 3). Unit MY I D3000 is configured with a repeater entry that has a Trigger = TOID and ID = 4203.
