Scan operations
The Model 2000 can be used with an internal scanner
card (Model 2000 SCAN or 2001-TCSCAN), or with
external scanner cards installed in a switching main-
frame (i.e. Model 7001 and 7002).
Step/Scan configuration — A “walk-through” menu is
provided to configure stepping or scanning. The main
menu is accessed by pressing SHIFT and then CONFIG.
Use the , , ▲ , ▼ and ENTER keys to select scan
type (INTernal or EXTernal), first channel in the scan
(MINimum CHANnel), last channel in the scan (MAXi-
mum CHANnel), time between scans, and reading
count (RDG CNT).
and keys — These keys can be used to manually
scan through channels on the internal scanner card.
Press to manually increment channels or to man-
ually decrement channels. Hold down either key to
scan continuously.
OPEN and CLOSE keys — Use these keys to open and
close channels on the internal scanner card. After press-
ing CLOSE, use the , , ▲ and ▼ keys to display the
desired channel (1 to 10) and press ENTER. Selecting a
different channel will cause the previously closed chan-
nel to open. For the Ω 4 function, CLOSE will close the
selected channel and the paired channel. Paired chan-
nels for the Model 2000 SCAN are 1&6, 2&7, 3&8,
4&9, and 5&10. Channel pairs are similar for the Model
2001-TCSCAN except that channels 1&6 are not paired.
STEP key — Pressing this key starts a stepping operation
of consecutive channels, where output triggers are sent
after every channel closure.
SCAN key — Pressing this key starts a scanning opera-
tion of consecutive channels, where an output trigger is
sent at the end of the scan list.
HALT — Pressing SHIFT and then HALT stops stepping
or scanning.
