Port Mode

Using the UECP protocol, the ports of the C04 are supporting three different modes:

Using the 'Unidirectional' and 'Bidirectional Requested Response' mode the user trusts the serial communication. There is no validation of the transmission. Only the 'Bidirectional Spontanous Response' ensures that the data transmission is correct. The C04 will send an ACK frame for each correctly transmitted UECP frame. Otherwise an error message will be displayed. The acknowledge frame will be analysed and displayed by ArcosII. To prevent resp. recognise transmission errors we suggest to set the port mode to 'Bidirectional Spontanous Response'.

Setting The Port Mode

Choose the 'Coder Ports' property page.

Select 'Bidir. requested response' in the 'Mode' Combobox and click on the 'Set All' Button. Now the data should be sent to the Encoder. To do so, check the 'Mode' Checkbox and press the 'Send' Button. Since the port mode might have changed now, you should check the connection to the Encoder again. ArcosII will determine the connection parameter automatically through this procedure.
