GoKart RFID Complete System Configuration Guide

System Overview

After extensive research and testing, we selected 4 devices from Chafon to build our GoKart lap timing system.

Equipment List

| Device | Model | Purpose | Qty | |--------|-------|---------|-----| | Fixed Reader | CF-815 | High-speed tag reading | 1 | | High-Gain Antenna | CF-RA1201 | Extend range to 15m | 1 | | Desktop Writer | CF-601 | Tag programming | 1 | | Anti-Metal Tags | G9811 | Mount on karts | 20+ |

Why CF-815 Reader?

Core Advantages

Impinj E710 Chip - Industry-leading
1100 tags/sec - Ultra-fast reading
4 Antenna Ports - Expandable
33dBm Output - Long range
Complete SDK - Easy C# development

Why CF-RA1201 Antenna?

12dBi High Gain

Standard 9dBi antennas read at 8-10m, while 12dBi reaches 15m, meaning:

Longer detection window at high speeds
Flexible installation positions
Better interference resistance

Why CF-601 Reader/Writer?

Designed for Programming

USB plug-and-play
50cm range sufficient
Keyboard emulation support
Cost-effective

Why G9811 Anti-Metal Tags?

Essential for Metal Environments

Kart bodies are mostly metal; regular tags fail. G9811's ABS shell solves this.

Durability

-20℃ ~ +100℃ operating temp
10-year data retention
10+ months trouble-free
