The key idea is identifying the uplink from the right-hand side device to the switch. In this topology, the RHS is wired to the designated uplink port on the first switch, which is Port 1. That port is typically set aside for inter-device connections and ensures traffic can flow toward the rest of the network (often as a trunk if multiple VLANs are involved). Other ports on the switch are generally used for end devices or additional links, so they wouldn’t serve as the intended RHS connection in this diagram.

The key idea is that per-device SAF totals live in the device-focused view of the system. Cellphie is the module that lets you inspect activity by individual PED, so you can see exactly how much money has been SAF’ed on a specific PED. The dashboard gives a broad, overall snapshot and isn’t guaranteed to show per-PED SAF amounts; reports are for historical tallies and typically aren’t the quick, per-device view you need; settings are for configuring features, not viewing live tallies. So, to find the SAF amount tied to a particular PED, open Cellphie and select that PED to view its SAF total.

This question focuses on which hardware component in a kiosk is typically non-user-serviceable and would need replacement by an OTP Pro or break/fix provider. The Kiosk Controller is the central processing unit—the brains of the system that coordinates all peripherals and software. When it fails, the entire kiosk is affected and requires specialized diagnostics, firmware loading, and careful reassembly, tasks that are handled by an OTP Pro or authorized break/fix technician. In contrast, the biometric reader, receipt printer, and PED multiport cable are peripheral or modular parts that are designed to be swapped or serviced more readily in the field, without reconfiguring the whole system. So the Kiosk Controller is the component most likely to require replacement by a pro.

In a KVS controller setup, each monitor feed is mapped to a specific video output on the controller so every display gets the correct signal. Kitchen Side 2 uses the second video output, which is the designated port for that zone’s monitor. This keeps the feeds properly routed and avoids mixing signals. Serial Port 2 is for control or communication with devices, not for video to the monitors. HDMI and DisplayPort are general video interfaces, but the system’s established mapping assigns Kitchen Side 2 to the second video output, not to those ports.
