There is no BUZZER I/O on the NEO Splitter board.
Note that both PAB and SAB systems also contain one "Coupler board" (impedance
matching board). The diagram below shows the 8.2 MHz RF signal path (other cabling
and hardware features not depicted), showing how TX1 and TX2 are used in this scenario:

Hub Board
The A1204 Hub Module delivers optional features, namely
Wired
connectivity, utilizing
the LAN9514 USB Hub and Ethernet Controller IC.
There is 1 USB Upstream port – used for the Upper Bay data connection (USB 2.0
interface with the System Controller).
USB Downstream ports (4) are used as follows:
1. EAS Sensor connection (USB to UART).
2. External USB-to-Ethernet dongle which is only used on the Master system (which
connects to the External network). The Hub Board has an 10/100 PHY Ethernet
switch (unmanaged switch).
3. RFID Reader - USB data - via J19 board to board connector, 2x8 Pin Header.
The Hub Board also has load switches, allowing it to supply +12V DC to the RFID
Reader. The Hub Board also has two (2) RJ-45 connectors. These are labeled OUT and
IN, and have the Sync dedicated pins for Sync Out / Sync In chaining. 8-Conductor
Cables (Shielded Cat 5e / Cat 6 or better) are installed between the systems next to one
another, allowing all the RFID reader/antenna systems to maintain synchronization.
