Wiegand 26/34 to RS485 converter

The Jedrek WG26/34 unit converts Wiegand 26 and 34 signals to RS485 and back again in a single module. It identifies the Wiegand format automatically and requires no manual configuration. A built-in watchdog circuit resets the device if the firmware stalls, keeping the link alive without operator intervention. Power is drawn from a 9 to 15 V supply.

Installers extending legacy Wiegand runs

This converter suits installers who need to run Wiegand 26 or 34 data over longer RS485 cabling without replacing existing readers or controllers. Because the Wiegand interface carries no device address, a single unit cannot distinguish multiple readers on the same bus; buyers needing multi-drop topologies must look elsewhere. The fixed 9600 baud, 8-N-1 serial parameters also rule out systems that demand other speeds or parity settings.

Two units required for transparent extension

The manufacturer notes that a transparent Wiegand extension requires a pair of converters, one at each end of the RS485 segment. No configuration software, jumpers or address switches are bundled; the automatic format detection and watchdog reset are the only onboard intelligence. Buyers should budget for two modules and a suitable 9 to 15 V power source for each end.

Questions about this item

What power supply do I need to run this Wiegand-to-RS485 converter?

Connect a 9 V to 15 V DC source; the unit draws its operating current from that range.

Will my existing WG26 or WG34 readers work with this converter without reconfiguration?

Yes, the converter automatically identifies WG26 and WG34 formats and translates them bidirectionally with no manual setup.

How can I verify the link is healthy after wiring the converter?

The built-in watchdog monitors the MCU; if communication fails the converter resets itself, so a stable link means the watchdog has not triggered a reset.
