Products: LAN controller Promix - CN. LN.01 (sheriff - ln)
It is part of the Promix - Locker system. Designed to organize a network, scan the status of the Promix - Locker system controllers (connected to the controllers of identifier readers, control sensors, switches and other mechanisms) and transfer information via USB or UART interfaces.
The Promix - CN. LN.01 LAN controller (hereinafter referred to as the controller) is a part of the Promix - Locker control system and is designed to organize a network for controlling electromechanical locks, blockers, and other mechanisms and scan their current state (triggering of sensors, loss of communication, presentation of identifiers etc. ) via USB and UART interfaces.
The implementation of the access technology is carried out by a top - level device (server, PC, terminal, tablet, etc. ) that runs on common UNIX - like operating systems, Windows OS, as well as software for control devices with a UART interface.
The Promix - Locker system includes the following devices manufactured by Promix:
- electromechanical locks,
- peripheral controllers for controlling mechanisms (Promix - CN. PR.04, Promix - CN. PR.08),
- peripheral controllers for reading identifiers (Promix - CN. RD.01),
- electronic locks for mobile urban transport Promix - SM307,
- LAN controller Promix - CN. LN.01,
- converters / repeaters of the Promix - AD. RI.01 interface as signal amplifiers.
As well as:
- local network power supply,
- top - level device (server, mini - PC, terminal, tablet, etc. ).
The Promix - CN. LN.01 controller, in addition to collecting information about the access system, maintains the local network interface, short - circuit protection, galvanic isolation of the local network circuits and upper - level devices.
A simplified version of the network implementation is shown in the figure:
The upper - level operating system recognizes the controller as a virtual COM port, assigning a serial number.
