Citizen OPT-807 Short Range Dual GHz Dongle

Overview

The OPT-807 is a short-range dual-frequency wireless dongle designed to extend connectivity options for Citizen CL-S5, CL-S6, and CL-S70 series printers and mobile devices. This accessory provides dual-band GHz radio capability, allowing you to pair devices with supported Citizen hardware in environments where wired connectivity is impractical — warehouse floors, production lines, and mobile scan-to-print workflows. The OPT-807 mates directly with the IF5-ES04 interface module, making integration straightforward on compatible host equipment.

Compatibility

The OPT-807 is engineered for Citizen CL-S5, CL-S6, and CL-S70 series devices. It requires the IF5-ES04 interface module for integration — ensure your host device has an IF5-ES04 slot or expansion port before ordering. Verify with the device datasheet or contact the equipment manufacturer if you are uncertain whether your specific unit supports this interface module. Short-range coverage limits this to local deployment scenarios (warehouse counters, loading docks, adjacent workstations) rather than long-distance facility-wide wireless mesh.

Installation Notes

The OPT-807 connects physically via the IF5-ES04 interface — no software driver installation required beyond the host device's standard OS. Ensure the IF5-ES04 module is seated firmly in the expansion port before attaching the dongle. Dual-band operation means you can select 2.4 GHz for range or 5 GHz for reduced interference in congested RF environments; consult your device manual for band-switching procedure. Keep the antenna unobstructed — metal shielding, EMI-heavy machinery, and thick concrete can degrade signal. Test wireless range in your intended deployment area before full rollout.
