Comnet Small Size RS232/422/485 2&4W Bi-directional Universal Data Transceiver sm 1 - FDX60S1BM

Comnet FDX60S1BM Data Transceiver

Overview

The Comnet FDX60S1BM is a single-fiber, bi-directional data transceiver designed to carry RS232, RS422, or RS485 serial signals over fiber-optic cable. This is the right unit when you need to extend serial control over distance without ground loops or EMI coupling — typical in surveillance system installations where PTZ camera control, access panels, or ANPR readers must communicate back to a central control room or NVR. The FDX60S1BM model number identifies a small-form-factor transceiver drawing just 2W and operating across -40°C to +75°C, suitable for both indoor racks and industrial outdoor enclosures.

Compatibility

The FDX60S1BM works with any device that outputs or accepts RS232, RS422, or RS485 serial data — including PTZ camera controllers, access control panels, gate operators, and license-plate recognition (ANPR) servers. It connects via a single ST fiber connector, requiring a matching fiber run between two transceivers or a dual-transceiver backbone. Compatible with Comnet's recommended PS-A12060 power supply and operates on any 9–30 VDC source. The unit is industrial-grade and designed for permanent installation in surveillance infrastructure.

Installation Notes

Operating voltage range of 9–30 VDC means you can power from standard +12V or +24V DC supplies common in surveillance racks. The unit occupies 1 rack slot if mounted vertically. ST fiber connectors require proper polarity and alignment — always confirm fiber direction before termination. Maximum reach is 69 km on single-mode fiber or 4 km on multimode, depending on your fiber plant; confirm fiber type with your installer. Power consumption is negligible (2W), so no dedicated UPS branch is required. Operating temperature range supports outdoor equipment cabinets without climate control, though storage temperature extends to +85°C. Bit error rate below 10−9 ensures reliable serial transmission across long distances — critical for access control or camera command chains where a dropped packet can lock a door or miss a pan-tilt command.
