1. Connect the Storage Module to the 21X
using the SC12 cable.
2. Enter the appropriate commands as listed
in Table 4.2-2.
4.5 PRINTER OUTPUT FORMATS
Printer output can be sent in the binary Final
Storage Format (Appendix C.2) or Printable
ASCII. If using the *4 Mode to enable on-line
output, Printable ASCII is the only format
available.
In the Printable ASCII format each data point is
preceded by a 2 digit data point ID and a + or -
sign. The ID and fixed spacing of the data
points make particular points easy to find on a
printed output. This format requires 10 bytes
per data point to store on disk.
Figure 4.5-1 shows both high and low resolution
data points in a 12 data point output array. The
example data contains Day, Hour-Minute, and
Seconds in the 2nd - 4th data points. The
output array ID and time values (year, day, hour-
minute, and seconds) are always 4 character
numbers, even when high resolution output is
specified.
Each full line of data contains 8 data points (79
characters including spaces), plus a carriage
return (CR) and line feed (LF). If the last data
point in a full line is high resolution, it is followed
immediately with a CR and LF. If it is low
resolution, the line is terminated with a space,
CR and LF. Lines of data containing less than 8
data points are terminated similarly after the last
data point.
