Manual optoNCDT 1402 - Micro-Epsilon

Serial Interface RS422iIf the sensor operates with the ILD1401 data protocol, the measurement value is a 12 bit word, e.g. thebits D12 and D13 are 0.Replies with a length of 4 Bytes must be swapped according to the following rule:Reception: 0 1 2 3 4 5 6 7Conversion: 3 2 1 0 7 6 5 4This rule does not apply to values.8.2.2 ASCII FormatOutput of 5 characters (digits) in ASCII code for the digital value + 1 tag „CR“ (= 0x0D), i.e. a total of 6 characters.Digital values with just 3 or 4 digits are preceded by blank characters.Example: Digital value 2099Transfer: “_2099“ (preceded by 1 blank character) „CR“ASCII code (Hex.) 0x20 0x32 0x30 0x39 0x39 0x0DCharacters SP 2 0 9 9 CRiASCII characters can be easily shown using a terminal program.8.2.3 Request the Data ProtocolPC transmits “---R”.Sensor replies“---14CI1“ Sensor operates with the ILD1401 data protocol or“---14CI2“ Sensor operates with the ILD1402 data protocol.optoNCDT 1402Page 42
