The GS20 Connectivity Gateway Leader Module has two dedicated output GPIO that trigger follower devices or send Pass/Fail results to the host.
The number of Zebra Barcode Scanners connected to one output pin should not exceed 16 devices or the Maximum Forward Continuous Current (IFM=70mA @ TA).
While the follower devices are connected to the leader through IO, it is still necessary to connect followers and the GS20 to the Ethernet switch to ensure that the results from the followers are sent to the leader device.
The following diagram shows a GS20 Leader Module with two followers on outputs (FS40 and FS70). Terminal blocks are used to connect the output pin on the GS20 to the inputs on the FS40 and FS70. Follower inputs can connect to one GS20 output or split between two outputs. Follower devices are powered via a PoE switch. The GS20, follower devices, and the host PC are connected to the Ethernet switch via Ethernet cables. In this case, the GS20 is powered by a 24V DC power supply or PoE switch.
In this configuration, follower devices receive a trigger through TCP/IP from the host PC, triggering the follower devices through GPIO or TCP/IP (depending on configuration) and sending the result back to the host PC.
