Library. The NASA/GSFC ISOMAX telemetry frame sync board provides simple command and telemetry services in a PC104 form factor board. For use with the MV2x series VME boards, the ISOMAX frame sync board is mated with a Dynatem DPC104 VME-to-PC104 bus bridge board. The DPC104 card maps the ISOMAX register port addresses into the A16 VME address space. Also, the DPC104 board maps the ISOMAX interrupt levels onto VME interrupt vectors. {\bf COMMANDS\par } The ISOMAX frame sync board is able to receive the 16-bit data command word from the NASA/NSBF CIP. The reception of a command strobe from the CIP generates an interrupt to vector ISOMAX\_\-VEC\_\-CMD. The 16-bit command word may then be read by calling \hyperlink{ISOMAX_8h_a34}{ISOMAX\_\-cmd\-Read}(). The command buffer is only one deep, so available commands should be serviced promptly. {\bf TELEMETRY\par } The ISOMAX frame sync board is able to provide a simple telemetry system. Each board is capable of either transmitting or receiving fixed sized telemetry frames 128 bytes in size (ISOMAX\_\-FRAME\_\-SIZE). The telemetry frames are sent as a serial stream encoded in either NRZ or BI-PHASE formats. The transmission bit rate is commandable if the board is configured in transmit mode. The receive side board must be provided with a bit rate clock to recover the serial data. The ISOMAX frame sync boards can operate at a bit rate up to 1 Mb (ISOMAX\_\-MAX\_\-RATE). The ISOMAX frame sync board provides a 2 KB FIFO to buffer the telemetry data. The boards do minimal formatting on the data. The user must provide the frames pre-formatted on the transmit side. Each frame is viewed as an array of 64 16-bit words (ISOMAX\_\-FRAME\_\-WORDS):\par \footnotesize\begin{verbatim} ----------------------------------------- | Frame Sync Word = 0xeb90 (1 word) | ----------------------------------------- | | | | | | | | | | | | | Frame Data Words | | (62 words) | | | | | | | | | | | | | ----------------------------------------- | Checksum Word (1 word) | ----------------------------------------- \end{verbatim}\normalsize Every telemetry frame must begin with one 16-bit word set to 0xeb90 (ISOMAX\_\-SYNC\_\-WORD). The next 62 (ISOMAX\_\-DATA\_\-WORDS) 16-bit words are user data which the ISOMAX boards ignore. Finally, every telemetry frame ends with a 16-bit checksum word. If the ISOMAX frame sync board is configured as a transmitter, the the user must provide a series of 8 (ISOMAX\_\-FIFO\_\-FRAMES) for the \hyperlink{ISOMAX_8h_a32}{ISOMAX\_\-fifo\-Write}() function. The frames must be headed by a frame sync word and have the user data following. The \hyperlink{ISOMAX_8h_a32}{ISOMAX\_\-fifo\-Write}() will fill half of the telemetry FIFO. The ISOMAX frame sync board will generate interrupt vector ISOMAX\_\-VEC\_\-FIFO when the telemtry FIFO is at least half empty and ready to accept more frames. The telemetry transmit FIFO interrupts should be servived promptly to prevent FIFO underflow. If the ISOMAX frame sync board is configured as a receiver, the board will scan the incomming serial stream looking for the frame sync word value. Once found, the board will fill the telemetry FIFO with the incomming frames as long as the frame sync words are found at the proper locations in the serial stream. The ISOMAX board will generate interrupt vector ISOMAX\_\-VEC\_\-FIFO when the telemetry FIFO is at least half full and ready for a read. The function \hyperlink{ISOMAX_8h_a33}{ISOMAX\_\-fifo\-Read}() will return 8 (ISOMAX\_\-FIFO\_\-FRAMES) from the FIFO. The returned frames will still contain the frame sync words and checksum words. It is the user's resposibility to extract the data portion of the frames. The telemetry receive FIFO interrupts should be servived promptly to prevent FIFO overflow. {\bf CONFIGURATION\par } The function \hyperlink{ISOMAX_8h_a27}{ISOMAX\_\-configure}() sets the operaing mode of an ISOMAX frame sync board. Four modes are available \begin{TabularC}{3} \hline Mode Number & Macro & Description \\\hline 0 & ISOMAX\_\-MODE\_\-TX & Transmit user telemetry frames \\\hline 1 & ISOMAX\_\-MODE\_\-RX & Receive user telemetry frames \\\hline 2 & ISOMAX\_\-MODE\_\-TX\_\-TEST & Transmit test frames \\\hline 3 & ISOMAX\_\-MODE\_\-RX\_\-TEST & Simulate reception of test frames \\\hline \end{TabularC} The user telemetry modes ISOMAX\_\-MODE\_\-TX and ISOMAX\_\-MODE\_\-RX are as described above. The test modes ISOMAX\_\-MODE\_\-TX\_\-TEST and ISOMAX\_\-MODE\_\-RX\_\-TEST use a test pattern to verify the basic operation of the boards. In mode ISOMAX\_\-MODE\_\-TX\_\-TEST, the test pattern is transmitted with no other user intervension. In mode ISOMAX\_\-MODE\_\-RX\_\-TEST, the ISOMAX frame sync board pushes the test pattern into the telemetry FIFO as if it received the data stream from a transmitter. \subsection{Define Documentation} \hypertarget{ISOMAX_8h_a11}{ \index{ISOMAX.h@{ISOMAX.h}!ISOMAX_CHECKSUM_OFFSET@{ISOMAX\_\-CHECKSUM\_\-OFFSET}} \index{ISOMAX_CHECKSUM_OFFSET@{ISOMAX\_\-CHECKSUM\_\-OFFSET}!ISOMAX.h@{ISOMAX.h}} \subsubsection[ISOMAX\_\-CHECKSUM\_\-OFFSET]{\setlength{\rightskip}{0pt plus 5cm}\#define ISOMAX\_\-CHECKSUM\_\-OFFSET\ 63}} \label{ISOMAX_8h_a11} The offset in 16-bit words of the ISOMAX telemetry frame checksum word from the beginning of the frame. \hypertarget{ISOMAX_8h_a8}{ \index{ISOMAX.h@{ISOMAX.h}!ISOMAX_CHECKSUM_WORD@{ISOMAX\_\-CHECKSUM\_\-WORD}} \index{ISOMAX_CHECKSUM_WORD@{ISOMAX\_\-CHECKSUM\_\-WORD}!ISOMAX.h@{ISOMAX.h}} \subsubsection[ISOMAX\_\-CHECKSUM\_\-WORD]{\setlength{\rightskip}{0pt plus 5cm}\#define ISOMAX\_\-CHECKSUM\_\-WORD\ 0x0000}} \label{ISOMAX_8h_a8} The value of the ISOMAX telemetry frame checksum word if no errors have occurred.
