DCC-EX is free open-source software on your own hardware; the DR5000 was a capable DCC/MM station — but Digikeijs went bankrupt in April 2023. An honest comparison of both options.
The comparison between DCC-EX and the Digikeijs DR5000 is really a comparison of two very different situations. DCC-EX is an actively developed open-source project: free software, buildable on an Arduino Mega, ESP32 or STM32, with a growing community and regular releases. The DR5000 was at its time one of the most fully equipped DCC/MM stations in this segment — rich in buses (LocoNet, s88-N, XpressNet, built-in Wi-Fi) and with a Z21 compatibility mode. But: Digikeijs B.V. (Almere) went bankrupt in April 2023. There is no further production, no manufacturer support and the Digikeijs website is no longer active. The DR5000 is only available secondhand.
That context fundamentally changes the choice question. A DCC-EX build is forward-looking and actively supported. A DR5000 purchase is always a secondhand investment without future firmware updates or factory warranty. The comparison below reflects that reality honestly.
| DCC-EX (EX-CommandStation) | Digikeijs DR5000 | |
|---|---|---|
| Type | Open-source DIY or RTR kit — actively maintained | Factory product — EOL, secondhand only |
| Protocols | DCC only (14/28/128 steps) | DCC (14/28/128 steps) + Motorola MM |
| mfx | Not supported | Not supported |
| RailCom cutout | Yes (ESP32 + EX8874, v5.6.0, 2026) | Yes (global detector) |
| RailCom feedback to ModelRailPro | To be confirmed on a layout | Yes (global detector present) |
| Max. track current | EX8874 up to 5 A (practical 2–4 A) | Max. 3 A |
| Feedback buses | GPIO / EXRAIL (no s88, no LocoNet) | LocoNet B+T, s88-N, XpressNet/R-BUS |
| Wi-Fi built-in | Via ESP32 or Wi-Fi shield | Yes (802.11 b/g/n) |
| ModelRailPro connection | TCP 2560 (Wi-Fi/Ethernet) or USB | Via Z21 emulation, UDP 21105 — to be confirmed on a layout |
| Guide price | Software free; hardware ~€30–80 (indicative) | Not new; secondhand ~€150–250 (indicative) |
| Manufacturer | Community (dcc-ex.com) — active | Digikeijs B.V. — bankrupt April 2023 |
DCC-EX (EX-CommandStation) runs on an Arduino Mega, ESP32 or STM32 with a motor shield. You build it yourself or buy a pre-assembled RTR kit. Protocol: DCC only (14, 28 or 128 speed steps). Older Motorola locos will not run on DCC-EX without replacing the decoder with a DCC one.
Maximum track current depends on the shield. The EX8874 shield reaches up to 5 amperes; in practice 2–4 A is typical. RailCom cutout is available on the ESP32 + EX8874 combination (EX-CommandStation v5.6.0, released 2026). Full bidirectional RailCom feedback — where decoders actively send their address per block — is platform-specific and in development, and is to be confirmed on a layout towards ModelRailPro.
There are no built-in feedback buses (no s88, no LocoNet, no R-BUS). Feedback runs via EXRAIL logic and GPIO pins; external EX-IOExpander modules (I2C) are in development. ModelRailPro connects via TCP port 2560 over Wi-Fi or Ethernet, or USB serial. DCC-EX is also compatible with JMRI and WiThrottle. See the DCC-EX hardware page for the current connection status.
Guide price: software is free; hardware approx. €30–80 depending on shield and platform (indicative). No factory warranty; support via the DCC-EX community (dcc-ex.com).
The DR5000 was the flagship station of Digikeijs' DiMAX product line and stood out for its broad protocol and bus support. Protocols: DCC (14/28/128 steps, up to 9999 simultaneous addresses, 117 decoders simultaneously) and Motorola MM. No native mfx — mfx requires a Märklin CS or ESU ECoS. Selectrix is not confirmed in the primary DR5000 documentation and is not stated as a fact here.
The bus configuration was strong for the original price: LocoNet B (for boosters, max. 40), LocoNet T (for devices and detectors, max. 128 modules), combined XpressNet/X-BUS + R-BUS port, s88-N, LAN (100BaseT), built-in Wi-Fi (802.11 b/g/n) and USB. RailCom: global detector present. Maximum track current 3 A.
End-of-life: Digikeijs B.V. (Almere) went bankrupt in April 2023. There is no further production, no manufacturer support and the Digikeijs website is no longer operational. The DR5000 is only available secondhand, approx. €150–250 (indicative). When purchasing consider: no warranty, no future firmware updates and limited spare parts availability.
ModelRailPro connects to the DR5000 via its built-in Z21 emulation mode on UDP port 21105 — the station then emulates the Roco Z21 LAN protocol. The completeness of that emulation (which commands exactly, accessory and feedback polling) is to be confirmed on a layout.
