SECTION 4. EXTERNAL STORAGE PERIPHERALS
4-4
When on-line Storage Module or printer transfer
is not enabled and the *9 Mode is used to dump
new data, the start of dump pointer (PPTR) will
remain where it was when the dump was
completed or aborted until the next time the *9
Mode is entered. If the End of Dump location
(window 2) is changed while in the *9 Mode, the
TPTR will be set to its previous value when the
*9 Mode is exited. Changing the program and
compiling moves the PPTR to the current DSP
location.
NOTE: A printer dump is aborted by
keying #.

4.3 CASSETTE TAPE OPTION
The Model RC35 Cassette Tape Recorder or
equivalent can be left attached to the 21X for
continuous on-line data recording or it can be
periodically taken to the 21X site for the
manually initiated retrieval of the data
accumulated in Final Storage. The *8 Mode is
used to manually initiate tape transfer.
4.3.1 CASSETTE RECORDER
The RC35 Cassette Recorder offered by
Campbell Scientific is an inexpensive recorder
for use with the 21X (also compatible with the
CR10 and CR7 dataloggers). The
record/playback function of each RC35 is tested
by Campbell Scientific along with a head
alignment procedure prior to shipment.
21X/RC35 connections are made with the
SC92A Cassette Write Only Interface or the
SC93A Cassette Read/Write Interface. The 21X
turns the RC35 on and off by switching power
through the DC power input.
