  • Page 6: Introduction

    CMD600 Introduction The digital adjustable charge amplifier CMD600 has an Ethernet interface for configuration and digital data−streaming and a real−time signal output as " 10VDC voltag output. On power−up is output voltage −10V and both digital outputs are on logical state 0.

  • Page 7: Configuration Via Telnet Interface

    CMD600 Configuration via Telnet interface Configuration is done via standard TELNET protocol. Only one TELNET session is possible in given time. Charge amplifier accepts text commands, which are terminated with CR (hex code 0D). Optional LF characters are ignored. Charge amplifier accepts one command at once. After command is issued, charge amplifier will respond in maximum response time.

For the complete List of commands see chapter 3. 3.2 Parameters format Int (integer) is signed 32 bit number. Float numbers are always returned in float representation with 4 decimal places(example –3.4567E−9).

  • Page 9: Discovery Procedure

    CMD600 Discovery procedure When measurement application does not know the IP address of charge amplifier it can send UDP broadcast discovery packet. It should use Ethernet broadcast address (ff:ff:ff:ff:ff:ff) and IP broadcast address (ff.ff.ff.ff). The destination port should be 85 and source port should be 86. The packet should have 4 data bytes : 0x77, 0x68, 0x65, 0x72.
