This is a newly developed unit and the previous CU09 is not compatible with the AV series. The CCU10 position is fixed at the extreme left slot of the AQS. Differences from previous versions The CCU10 is based on the CU09 hardware is very similar to it in most respects. The principal differences are: 1. CCU10 has been fitted with a 90 pin middle rear connection replacing the 30 pin socket used in CU09. It can therefore not be used in older AQX systems. 2. CCU10 no longer has the tty10 and tty20 RS485 ports available on the RS232 Extension Unit. Consequently unlike CU09 the RS485 signals are not available on the front panel connectors ST8 and ST9. Note: Only one of the two ethernet connections can be used Console tty00 ST7: This is an alternative (to the ethernet) link to the workstation. Note that this RS 232 link is not actually necessary since all the information goes over the much faster ethernet link. However it is particularly useful if the ethernet link crashes.To allow for space the RS232 ports are physically located on the RS232 Extension Unit and joined to the CCU10 via a 50 pin SCSI cable. The connection is one to one.Reset button: see sec Front Panel link LEDS The LEDs labelled link on the front panel are an indication of the status of the ethernet link LED1: Indicates transmission of data. LED2: Indicates receiving of data. LED3: Indicates ethernet link is good. LED4: Indicates data collision has occurred. Figure 3.3. LINK LED Front Panel Display L I N K LEDs are labelled LINK on the front panel. Referred to as Fast Ethernet STATUS LEDs in technical manual LED3 should be permanently lit once the CCU10 has booted. Note that LED4 lighting would indicate a problem. Front Panel status LEDS Figure 3.4. Status LEDs STATUS LEDs are labelled STATUS on the front panel. Referred to as ACTIVITY LEDs in technical manual Although these LEDs do follow a test procedure during booting the pattern is too fast to follow. At the end of the booting the leftmost LED (LED4) should remain permanently lit signifying that all tests have been passed. Connection of tty00: This connection will depend on whether the host workstation is an O2 or a PC. If it is an O2 the connection should be made to the COM2 port at the rear. If it is a PC the connection should be made to the Serial B port. On previous CUs this connection was RS232 SubD type, however to save space it is now round. Logging onto spect After rebooting the CCU10 it is customary to log onto spect. This is physically logging onto the CCU10 and is usually done with the RS232 connection to tty00. The window interface is called up by clicking on the CCU Hyperterminal icon of the host workstation graphics monitor. Note that you can also use telnet spect to access via the ethernet link. Reset If the CCU10 hangs then it may be necessary to initiate a reset. A reset can be effected in three ways: 1. by pressing the red button on the front panel 2. by switching the AQS off and on at the mains 3. by activating a software reset with commands such a init 5. The effect of the reset is to put the various VME bus units into a defined state. The re-booting after a reset can be most easily observed by clicking on the CCU Hypertermina licon. Exchange of the CCU10 can be carried out as follows: 1. Shut down the CCU10 with the init 5 command and switch off the AQS. 2. Remove the unit and replace 3. Switch on the AQS 4. Observe the booting up using the Hyperterminal icon 5. The message system is ready will signify that the booting is complete. 6. Check the the rs232 link is OK by logging onto spect. 7. Check that the ethernet link is OK by ensuring that the link LED is lit or by using the telnet spect command Note that you can also log onto spect over the ethernet connection using the telnet spect command. Service Manual Version 001 BRUKER 47 (187) 48 Communications Control Unit CCU10 Diagnostic Tests 3.7 There is no specific diagnostic test for the CCU10. If the system boots then this is every indication that the CCU10 is functioning. Note: The CCU10 is the successor of the older SIB unit. Do not attempt to run this test as it will crash the system. Software 3.8 In the cf routine tty10 is reserved for the RX22 tty20 is reserved for the ACB. Both of these are RS485 links that are transmitted over the backplane. Full duplex mode is not supported by the software. Specifications RS232 Channels 2 RS485 Channels The CCU10 on-board chip operating frequency is 100 MHZ, though the effective transmission frequency drops to 50 or 25 MHz depending on the bus used to communicate with other on-board components. Half duplex means that data transmission is allowed in one direction only at any given time. Full duplex ( which is data transmission in both directions during any given time interval) is not supported. Although the CCU10 hardware manual refers to the possibility of having 16,32 or 64Mbyte of DRAM, all units to date have been fitted with 64Mbyte as standard. Power Supply and Fuses 3.10 The digital power supply provides the CCU10 with the required voltage levels via the backplane and the power requirements are listed below. Service Manual Version 001 BRUKER 49 (187) 50 Communications Control Unit CCU10 50 (187) BRUKER Service Manual Version 001 51 Timing Control Unit TCU3 4 4 Introduction 4.1 The TCU3 is a single slot-in unit located in the AQS rack. It replaces TCU0 and TCU1 (the TCU2 was not introduced) and is the first TCU version compatible with the new AV series. A single TCU3 is designed to provide all the required timing signals for a spectrometer with up to 8 RF channels. As a general overview the TCU3 can be thought of as controlling the timing of events on various other VME units via signals transmitted along the AQS backplane providing a set of precisely timed outputs from the front panel which are available to drive other spectrometer units. Very generally the performance of the TCU3 can be viewed in terms of how precisely it can control the timing of various events (timing resolution) as well as how many events it can control (number of outputs). As a result many of the front panel outputs are currently not connected in the standard configuration. Only the top few outputs of T2 ( T2 A,B,C) are normally connected and connector T1 is used only for solids. There is effectively little of no distinction between the front panel outputs and backplane signals. Where possible signals are transmitted along the backplane to the various units. However units such as external amplifiers, QNP Pneumatic Unit BSMS etc.Most of the timing control takes place via the F and Acq buses which run along the backplane. From a service point of view relatively few of the TCU3 functions are accessible to test and measurement. Service Manual Version 001 BRUKER 51 (187) 52 Timing Control Unit TCU3 Specifically the functions of the TCU3 are to 1. synchronize and control the timing of the RCU and GCU. 2. control the implementation of frequency lists by the FCU via a set of timing sequences 3. generate various front panel switching signals used in external amplifiers, QNP Pneumatic Unit, BSMS etc. 4. to provide the RCU and GCU with a 40 MHz TTL clock signal. (This clock signal actually originates from the 20MHz signal supplied by the the REF. unit.) 5. Generation of the RCUGO signal for the RCU and AQS signal for the GCU. A complete list of the TCU3 outputs is given at the end of this Chapter. All outputs of the TCU3 are TTL active low. The outputs are designed to go high after a hardware reset of the CCU MHz internal signal. The timing of the TCU3 is implemented using an 80 MHz internal clock. This signal is generated on-board by quadrupling the 20MHz from the REF. unit. Note that the voltage level is TTL. Backplane bus Connections The TCU3 is connected to the FCU's, RCU and GCU via three buses, the Acquisition bus, the VME bus and F bus which run along the AQS backplane. Acquisition bus: This is a 16 bit data, 8 bit address real-time bus.the TCU3 is the one and only master of the Acquisition bus, guaranteeing control over critical acquisition timing. VME bus: This is a 32 bit bus used for general non timing critical communication and the CCU is normally master of this bus ( The TCU and RCU can also be master). The details of the timing within a pulse program would be made known to the TCU3 via the VME bus. F bus: This is a new 32 bit communication bus that is used by the TCU3 to communicate (non real time) with the FCU and GCU. The TCU3 is master of this bus. Through this bus the TCU3 effectively ensures that frequency sequences are loaded correctly into the FCU and correctly implemented. The TCU3 contains the termination resistors of the 20 MHz reference clock signal from the REF.

Now however this can be done with the PALS in situ. A connection (ST8) is available on the VME extender board to facilitate PAL downloading via a laptop in the field. A connection is made between ST8 and the laptop parallel port. To download using the VME Extender board W11 is set.if however the download is to be done using a cable directly onto the unit ( without extender board) then W11 should be unset. On the TCU3 ST8 is used as the connection to download PALS in chain 1 and ST10 is used as the connection to download PALS in chain 2. To date however downloading of pals with new firmware has not been required. The remaining T2 connections are not normally required. The signal is received from REF Unit after being daisy chained through the FCUs. This signal is to ensure synchronization with the various timing sensitive units. The 50 Ohm termination resistors for this signal are located on-board the TCU3.
