Communication protocol Baud rate 115200, data bits 8, stop bit 1, no parity bit:
A command begins with instruction code and ends with a carriage return '\r' (ASCII 0x0D). Multiple commands can be transmitted with a semicolon as separator. For example, single command: 'help\r' or multiple commands 'ac=100;ac;dc\r'.

There are 'read' and 'write' command types. 'Read' command only gets a value or parameter, 'write' command sets a parameter and shows a current value of the parameter in the response.

For example, read command (get current acceleration):
controller read command: 'ac\r'
controller response: 'ac=1000\r'

For example, write command (set current acceleration to 2000 steps/sec2):
controller write command: 'ac=2000\r'
controller response: 'ac=2000\r'

e-Trigger
4-Channel Encoder Trigger: 9...36V
Powered, Quadrature Encoder Interface for frequencies up to 1000KHz with 100Mbps Ethernet Interface

eTrigger is an innovative system that allows the continuous monitoring of the encoder state and produce a trigger output at the exact encoder positions. Up to 4 separate encoder positions may be used for triggering purposes.

It's a perfect solution for an automatic control of industrial and commercial machine vision applications. High speed communication is the key for a flexibility and efficiency. The ability of “on the fly” injections, gives the opportunity to reach the optimal performance and save your time for trigger configuration.

The build-in processor is used to calculate not only the status of the encoder, but also the trigger point in advance*, depending on velocity of the motor. The Hardware supports up to 1000 KHz Encoder Frequency.
