Read and Store Digital Input Data
FASTDATA Read digital bits 0-7 as fas t as possible
These commands read the respective byte of digital input data and store it in SRAM at the fastest
possible rate: 21 microseconds between samples. The commands will store as much data as the pod
can hold: RAM size-1KByte. Typically, this is 7Kbytes of data, however, a 32k RAM version is
optionally available, which would provide 31Kbytes of data storage.
Once the data has been stored, it is dumped to the serial port. The data is formatted into 3-byte
chunks, followed by a space: xxxxxx xxx...etc. There are no carriage returns until the last byte has
been sent.
All normal pod activities (parsing comm ands, receiving commands, pulse output countdowns, free-run
generation, COS detect, etc.) STOP until the serial data is done transmitting. NOTHING else works
until the data has been dumped.
Re-send Data
D This will dum p the last stored historical data to the serial port.
Data can be resent by issuing a "D" comm and. This will dump the last stored historical data to the
serial port and can be used, for example, if line noise or similar problems are suspected.
This command should only be used after FASTDATA has been issued, because random data fills the
buffer until one of these commands acquire data.
The format of the data is identical to the FASTDATAx commands. See the previous description of
the FASTDATAx comm and for more information about the format and length of returned data.
Example:
Resend the data buffer
SEND: D
RECEIVE: xxxxxx xxxxxx xxxxxx ... xxxxxx for size of buffer.
Entering a New Program
PROGRAM= This command initiates the transfer of a new program to the W M-IIRO-8.
This command should be used carefully. If you accidentally issue a "PROGRAM=" command, ESC
(ASCII 27) will restart the pod as if power had been reset.
This feature is designed to allow ACCES to provide field-upgrades to the W M-IIRO-8 firmware, and,
for advanced users, the opportunity to customize the firmware in the pod. Documentation relating to
the use of this comm and is provided with the CD, or is available separately for a small fee.
