1 Dt sheet Issue 3, 14 th July 2014 E201 USB Encoder Interfce E201-9Q - incrementl E201-9S - bsolute bsolute SSI BiSS-C mode (unidirectionl) B Z Clock Dt M SLO The E201 is single chnnel USB encoder interfce suitble for use with wide vriety of 5 V rotry nd liner encoders. It llows encoders to be esily interfced nd powered from PC using only USB cble. The E201 is vilble in 2 versions: E201-9Q supporting incrementl encoders E201-9S supporting bsolute SSI nd BiSS-C mode (unidirectionl) encoders Both stndrd versions re pin comptible with RLS rotry nd liner mgnetic encoders. The interfces cn lso be used with Renishw encoders. Two sttus LEDs re included to indicte USB sttus nd encoder ctivity. Demo softwre instlltion Downlod nd instll the demo softwre from During the instlltion ll necessry drivers re instlled. When instlltion is completed, connect the E201 interfce nd configure the softwre for the encoder you will be using. Encoder supply voltge nd current consumption cn be red out by the softwre. Power supply to the encoder cn be switched on/off by the softwre. For custom development of softwre, detiled explntion of the SCII commnds cn be found in this dtsheet under the Progrmming commnds section. pplictions Encoder functionl test Encoder demonstrtion Metrology Guging PC bsed mchinery ssocite compny

4 Dt sheet Progrmming commnds NOTE: Note this section is only needed if you wish to develop your own softwre. The E201 is provided with simple disply softwre. This section contins detiled informtion on the communiction between the E201 interfce nd PC which is needed to develop customised softwre. Instlltion of USB Drivers Downlod the E201 softwre which includes the USB drivers from nd follow the instlltion steps. The drivers will be instlled during the softwre instlltion. The E201 interfce will pper s new Virtul COM port on the computer. The ctul port number ssigned depends on how mny COM ports re lredy in use on the PC. In Windows 7 this cn be found under: Control Pnel > System > Device Mnger > Ports (COM & LPT) Supported operting systems: 32-bit nd 64-bit Windows (XP, Vist, 7 nd 8/8.1) Communictions The E201 interfce responds to SCII commnds received over the USB cting s virtul seril port. No CR chrcter is required fter ny commnd. Speed settings of the virtul seril port cn be ny vlue. 4
