AzLM Axle Counter systems may be monitored by direct Ethernet or USB connection.
No additional configuration files are required prior to installation.
Ethernet connection is the most economical, but is not possible where the Ethernet connection is already in use.
1 x S-LX may monitor 2 x Axle Counter Evaluators. (ACE) over Ethernet.

...

Where the Ethernet connection is use. Follow the guidance for connection over USB. 1 x S-LX may monitor 1 x Axle Counter Evaluators. (ACE) over USB
In the USB Configuration, Additional ACEs may be monitored by utilising both serial ports on the Internet connected S-LX compute device, or via bridging the Wireless connection through multiple S-LX devices. Contact MPEC for more information to ensure safety requirements are met.

Note

Connection of the S-LX system is via a monitoring port. The AzLM system may remain in service during installation.
Safety is assured by only connecting to 1 of duplicated or triplicated CPU devices found in each ACE. (2oo2 or 2oo3 safety system) (See SLX-TYP-AZLM-1)
Where Ethernet ports are already in use on all ACE CPUs, connection via USB is required, using a special “air-gapped” variant of the S-LX in order to control safety and reliability risks to a tolerable level. (See SLX-TYP-AZLM-2)
Appropriate cables shall be provided by the customer for Ethernet connection
