DS6400 REFERENCE MANUAL4844.3 AUXILIARY INTERFACEThe auxiliary serial interface is used exclusively for RS232 point-to-point connections. It isprincipally used for scanner configuration from a laptop PC but is also available for LOCALECHO to a monitoring PC or for Pass through layouts. This interface is active when the DataTx parameter is enabled. The overall maximum cable length should not exceed 15 m (50 ft).The following pins of the 25/26-pin connector are used for RS232 full-duplex interfaceconnection:Pin Name Function20 RX Receive data21 TX Transmit data23 GND Common GroundDS6400 USER INTERFACE23 GND GNDTXDRX20RXDTX211EarthGroundCHASSISFigure 61 - RS232 Auxiliary Interface Connections4.4 INPUTSThere are four optocoupled polarity insensitive inputs available on the 25/26-pin connector ofthe DS6400 scanner: Input 1 (External Trigger/PS), Input 2 (Encoder), Input 3 and 4 genericinputs:The electrical features of these inputs are:Maximum voltage 30 VdcMaximum current all Inputs: 12 mAPin Name Function18 I1A External Trigger (polarity insensitive) for PS19 I1B External Trigger (polarity insensitive) for PS6 I2A Input Signal 2 (polarity insensitive) for Encoder10 I2B Input Signal 2 (polarity insensitive) for Encoder14 I3A Input Signal 3 (polarity insensitive)15 I4A Input Signal 4 (polarity insensitive)24 I34B Common Reference of Input 3 and Input 4 (polarity insensitive)The active state of all the inputs is selected in software (open or closed). Refer to theGenius™ Help On Line.All inputs are optocoupled, polarity insensitive, and driven by a constant current generator;the command signal is filtered through an anti-disturbance circuit which generates adebouncing delay which can be set to 5 ms or 500 s. In particular, I1 for PS, I3 and I4 share
