                              DATA TRANSFER MODULE (DTM)

        13.1  GENERAL DESCRIPTION

        This single-width module, model 6032, transfers data (duplex,  serial)
        between   two  CAMAC-interfaced  computer  systems.   Therefore,  6032
        modules are most commonly used in pairs, one 6032 being plugged into a
        CAMAC   crate   of  each  system,  with  the  two  modules  physically
        inter-connected by two data lines and two control lines.  Each  module
        contains  two 256 words x 16 bits memories, combined with the parallel
        formatted CAMAC dataways.  In addition, a front panel port  interfaces
        the  module  to  the  MDCX  channel  over  which  the  controls system
        transmits serial block transfers independent of the CAMAC dataway.
        A software maskable LAM bit  is  set,  following  a  time-out  at  the
        conclusion  of  a  Receive Data (RD) serial block-transfer to indicate
        that data is available to be read via the dataway.  Software  readable
        status  provided  for each memory includes content (binary word count)
        and "full" and "empty" flags.

        13.2  CAMAC COMMAND DESCRIPTION

                F0 AX   Clears LAM and reads F0 memory.
                F1 A0   Reads module status; also inhibits intermodule R/W
                        transfers for 20 msec. to freeze data prior to dataway
                        MDC reads.
                F4 AX   Same as F0 AX.
                F6 A0   Reads module No. (binary).
                F8 A0   Tests LAM, Q returned if set and enabled.
                F9 A1   Clears F0 memory.
                F10 A0  Clears LAM.
                F12 A0  Disables internal memory jumper.
                F14 A0  Enables internal memory jumper.
                F16 AX  Writes one word into F16 memory.
                F24 A0  Disables LAM.
                F26 A0  Enables LAM.
                F28 A0  MDCX OFF.  Inhibits block transfer.
                F30 A0  MDCX ON.  Enables block transfer.
                ZS2 + POWER ON clears memories, LAM, LAM Disable.
