Bcd Interface (X33) - HEIDENHAIN ND 282B User Manual

BCD Data Interface (X33)
There are several ways to start measured value output:
ä
Press MOD repeatedly until the PRINT indicator blinks
(only for"slow" data output), then start data output with
ENT;
or
ä
Let the measured values periodically be sent to the data
output;
or
ä
nput a latch command at the D-sub connection EXT;
or
ä
nput a latch command at the BCD connection.
Interface Operating Mode (see Operating Parameter P53)
slow– Display value
fast – Display value referenced to datum 1
(MIN/MAX/DIFF display values are not shown)
You can order a connecting cable (to a PC, for example) from
HEIDENHAIN (Id. Nr. 206 420-..); maximum cable length 10 m.
Operating parameters for display output: P23, P53 to P57,
P84.
