PAI connects to Paradox alarm panels across three product families: Magellan (MG), Spectra (SP), and EVO. All panels expose a serial port (TTL 5V) that PAI uses to communicate, and the IP150 module can be used as an alternative connection method for all families. Support for Magellan, Spectra, and EVO panels is very stable. If you find a bug, please report it.

​
Panel families

EVO

Digiplex EVO series. Supports up to 192 zones, 8 partitions, access control doors, and up to 999 users. Requires firmware below 7.50.000 for serial connections.

Spectra

SP series panels including SP4000, SP5500, SP550+, SP6000, SP6000+, SP65, SP7000, and SP7000+. Tested with SP7000.

Magellan

MG series wireless panels including MG5000, MG5050, MG5050+, and MG5075. Tested with MG5050.

​
Connection methods

PAI supports two connection methods for all panel families.
All Paradox panels include a built-in serial port (TTL 5V). You can connect directly via:
  • The panel’s onboard serial port (requires a TTL level shifter)
  • A USB RS232 TTL adapter (CP2102, PL2303, CH340, and others)
  • Serial over TCP using an ESP32 or Arduino as a serial proxy
Panel familyDefault baud rateNotes
Magellan (MG)9600
Spectra (SP)9600
EVO9600Use 38400 (default EVO setting) or 57600 for EVO panels
Do not upgrade EVO firmware to version 7.50.000 or higher if you use a serial connection. See the EVO panel page for details.

Host hardware

PAI has been tested on the following single-board computers connected via built-in serial port (with a TTL level shifter) or USB RS232 TTL adapters:
  • OrangePi 2G-IOT
  • NanoPi NEO
  • Raspberry Pi 3
When using the panel’s built-in TTL serial port, a level shifter is required to safely interface with 3.3V or 5V GPIO on host hardware.
