    Torridon HS Lite Drive Control Module - Technical Manual Mechanical Characteristics: 15.3 (0.602) 2.7 (0.106) 69.85 (2.75) 4.8 (0.19) (4.00)  The Modules have the same cross section as a 2.5” disk drive, allowing them to fit into any 2.5” or 3.5” drive enclosure.

  • Page 9: Control Interfaces

    Torridon HS Lite Drive Control Module - Technical Manual Control Interfaces All Torridon Control Modules are designed to be used with a Torridon Array Controller (QTL1079) or a single Torridon Interface Card (QTL1144). The control cable is an ultra-thin Flex cable.

  • Page 10: Drive Presence Support

    Torridon HS Lite Drive Control Module - Technical Manual Drive Presence Support The module supports three different proprietary drive presence circuits, all are switched by the same control signal SPECIAL_1. If the detection circuits are not implemented on the backplane this circuitry should have no adverse effect on drive operation.

  • Page 12: Basic Concepts

    Torridon HS Lite Drive Control Module - Technical Manual Basic Concepts Each switch on the Torridon control cards is called a ‘Signal’ and can be programmed to follow one of 6 programmable delay profiles (called ‘Sources’). This allows the user to sequence power and signal connections to the drive in up to six programmable steps.

  • Page 14: Signal Configuration

    Torridon HS Lite Drive Control Module - Technical Manual Signal Configuration Each signal that is switched by the module is usually assigned to one of the 6 timed sources, S1 – S6. Each signal can also be assigned directly to ’always off’ (source 0), ‘immediate change’ (source 7) or ‘Always on’...

  • Page 15: Power Up Vs. Power Down Timing

    Torridon HS Lite Drive Control Module - Technical Manual Power Up vs. Power Down Timing Each control source is always configured with power-up parameters; the power-down profile is automatically generated by the module, and is the mirror image of the power up:...

  • Page 16: Voltage Measurements

    Torridon HS Lite Drive Control Module - Technical Manual Voltage Measurements The modules are capable of measuring various voltages both for self test and to assist in the testing of a customer’s system. The following measurement points are available: Measurement Command...

  • Page 17: Default Startup State

    Torridon HS Lite Drive Control Module - Technical Manual Default Startup State On power up or reset, the control modules enter a default state. To make the module as easy to use as possible, the default state is a ‘standard’ hot-swap scenario with preset source and signal settings such that the “run:power up”...

  • Page 18: Controlling The Module

    Torridon HS Lite Drive Control Module - Technical Manual Controlling the Module The module can be controlled either by:  Serial ASCII terminal (such as HyperTerminal) This is normally used with scripted commands to automate a series of tests. The commands are normally generated by a script or user code (PERL, TCL, C, C# or similar).
  • Page 19 Torridon HS Lite Drive Control Module - Technical Manual Clear the terminal window and displays the normal start screen. Also runs the internal self test. The same action can be performed by pressing return on a blank line. *IDN? Displays a standard set of information, identifying the device. An example return is shown below...
  • Page 20 Torridon HS Lite Drive Control Module - Technical Manual CONFig:TERMinal ? Returns the current terminal mode DEPRECATED COMMANDS – Provided for backwards compatibility, we strongly suggest you use the ‘Signal’ and ‘Source’ commands instead. REGister:READ [0xAA] Returns the value of the register with address [0xAA]. [0xAA] should be in hex format and preceded by the suffix “0x”.
  • Page 21 Torridon HS Lite Drive Control Module - Technical Manual SOURce:[1-6|ALL]:DELAY [#ms] SOURce:[1-6|ALL]:DELAY? Sets the initial delay of a source in mS. The delay is entered as a decimal number with no units. E.g. “Source:1:delay 300”. SOURce:[1-6|ALL]:STATE [ON|OFF] SOURce:[1-6|ALL]:STATE? Sets or returns the enable state of the source. Any signals assigned to a disabled (off) source will immediately be disconnected and vice versa.
  • Page 22 Torridon HS Lite Drive Control Module - Technical Manual is the master control for all switches on the card. The same action can be performed by writing this bit directly. The command will fail if you order a power up when the module is already in the connected state and vice-versa as the action cannot be performed.

  • Page 25: Source Registers

    Torridon HS Lite Drive Control Module - Technical Manual Source Registers Each source is setup by a block of 9 16-bit wide registers. Below is the register map for a generic source. The list of registers in the title indicates the actual address of the byte in each of the 6 timed sources.

  • Page 28: Appendix 1 - Signal Names

    Torridon HS Lite Drive Control Module - Technical Manual Appendix 1 - Signal Names The following signal names are used to specify a single signal or a group of signals. These may be used in commands that take a parameter “SIGNAL_NAME”. Note that some commands, such as those returning a value, only accept a parameter that resolves to a single signal.
