Page 6: Overview
ACURA’s 2 Overview The L-A210 Serial reader is the latest incarnation of the classic RS232, RS485 type network and part of the new generation of patch lead friendly products including the L-A211 and IPSU. ... -
Page 7: New Generation Reader Properties
ACURA’s 2.1 New Generation reader Properties The L-A202/L-A210 and L-A211 family are significantly different from there predecessor the L-A201. These differences are summarized here and explained in more detail throughout the manual. Front End Filtering The L-A202 / L-A210 / L-A211 utilize front end RF filtering allowing them to work extremely effectively in noisy RF environments including in direct proximity to other 433MHZ emitters including TETRA band. -

Page 9: Hardware Configurations
ACURA’s 3 Hardware Configurations. ACURA’s recommend the following configuration methods Single reader for Demo Purposes The L-A210 when used as a standalone unit can draw power over the USB USB lead L-A210 Reader Network USB Host to RS485 The IPSU supports USB, RS232 and RS485 allowing it power up to 8 readers over RS485* Dependent on cable lengths. -
Page 10: Networking
ACURA’s 4 Networking 4.1 Single Network structure The L-A210 readers are connected together in a daisy chain type format. That is, Reader 1 is connected to Reader 2 is connected to Reader 3 etc. The network can handle a maximum of 254 readers because of addressing constraints. -
Page 11: Basic Network Operation
ACURA’s 4.2 Basic Network Operation Data passed up and down this network is arranged in a packet format. (Explained later). Each reader can be individually addressed via 2 address techniques, or the entire network can be broadcast to by assigning the destination address as value 255. -
Page 12: Establishing Node Id Addressing (Automatic Assignment)
ACURA’s Each Command and Response is formatted into a specific packet of data with error checking etc included in the protocol format. Data can only flow in one direction at a time since the hardware is using a single serial port to control all this serial data. In order to make the installation of this system easier, it was necessary to stop the need of having to give each reader and individual address via a dipswitch or other plug in computer methods. -
Page 13: Packet Control
ACURA’s 6. Once Reader 1 has been established, it will start continuously sending its NODE ID out of the right hand RS485 port. This will be a continuous ' 1 ' and lasts for 500ms. 7. - Page 14 ACURA’s RS232 2 wire RS485 2 wire 2 wire 2 wire 2 wire RS485 RS485 RS485 RS485 "ABCD In the idle mode, data can be received from either direction. Since there is only one serial port on the microprocessor, the header byte received will determine from which direction the packet is being received.
-
Page 15: Auto Polling
ACURA’s Each time a valid packet is received, the Packet RX LED will flash. This can be used to determine whether valid communications is taking place. Response packets are now sent back exactly the same way as the command packet, but in the opposite direction. - Page 16 ACURA’s Auto Polling sequences start with a complete system communications reset to ensure that the network is seen correctly. This happens each time the auto polling is switched on even at power up. RX210 User Manual Page 16 of 35 ...

Page 17: Protocols And Addressing
ACURA’s 5 Protocols and Addressing As mentioned earlier data flowing on this network have a specific packet format. This format is defined as follows: 5.1 Command Packets Data Network Receiver Node Command Data Checksum All bytes are HEX Values ... -
Page 18: Addressing Techniques
ACURA’s 5.3 Addressing Techniques The addressing system for these networks has been made as flexible as possible. This will allow for various configurations and keep the system open for later expansion etc. When addressing a reader, there are 3 addresses to take into account:- 1. - Page 19 ACURA’s Some examples would be as follows:- Invalid - will have no response Access Reader with Reader ID = 12 Access Reader 5 on the network Access Reader 5 on the network. Reader ID address is ignored Invalid - will have no response Access Reader with Reader ID = 4 on Network 1 Access Reader 123 on the Network 1...

Page 21: Command Details
ACURA’s 6.2 Command Details Reset Network Command The function of this command is to reset the entire network, and re-establish the NODE ID addresses. The NODE ID address in the command packet should hold a 255 (broadcast value) to ensure that the entire network enters into the reset sequence. -
Page 22: Disable Auto Polling Command
ACURA’s Disable Auto Polling Command The function of this command is to disable future Auto Polling after power up by resetting the Auto Polling flag in the Data EEPROM. This command can be addressed directly to reader 1, or on a broadcast basis. ... -

ACURA’s Get Environmental Noise Level Value This command will retrieve the calculated value (between 0 and 255) of the environmental white noise level. Take note that this command can only follow after the Start Environmental Noise Level Value Calculation. If a command is send down to the unit, while still in evaluation mode, the reader will cancel the calculation process, reset and continue normal operation. -
