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.
