2. 2 Preliminary DCS technical specifications (v1.0) for the GTK-RO electronics Topics:  Introduction  Types and quantities of standard VME crates  List of GTK-RO status variables  Preliminary list of TDC-pix status variables (to be defined with Alex) DCS Meeting, CERN (vydio), Jun 25th 2013, A.

3. 3 “off-detector” readout electronics for the Gigatracker (GTK_RO): status report  Introduction This document describes the types of crates and modules composing the “off- detector” readout system for the GTK subdetector. The DCS should perform a set of standard control / monitoring functions on the crate power supplies of the “off-detector” electronics. The “off-detector” GTK readout card (GTK-RO) will also monitor some local variables whose status could be monitored by the DCS and this document provides a list of such variables. This document does not cover the topic of configuring the Gigatracker ASICs (“TDCpix”) configuration. The Gigatracker subdetector PCs will maintain the information concerning the configuration and the status of the TDCpix on the GTK stations and the handling of these parameters will then be covered in a separate document.

4. 4 “off-detector” readout electronics for the Gigatracker (GTK_RO): status report  Types and quantities of standard VME crates Four VME crates located in the farm room: they are one each in rack S16 and S14 and two in rack S15 (of the 2 in rack S15 one if for the GTK-RO cards and one is for the main timing unit) The characteristics of the VME crates (all are the same) for the “off-detector” electronics are summarized in the table below: DCS Meeting, CERN (vydio), Jun 25th 2013, A.
