BANDWIDTH:
Monitors channels 1 to 6 ("Low" = low bandwidth, and "High" = high
bandwidth). Enter (2) to change bandwidth.
INHIBIT:
Monitors inhibit status for channels 1 to 6 ("Inh" indicates data inhibited,
"Track" indicates data is tracking). Enter (4) to inhibit a channel.
RESOLUTION:
Monitors resolution for channels 1 to 6. Enter (3) to change resolution.
(Options 10, 12, 14 or 16 bits).
Encoder Mode Information:
Provides A quad B outputs (0 for “Off” and 1 for “On”). Enter (6) to change
encoder mode. Enter (12) to change A quad B (encoder) resolution.
Note:
The Encoder must be enabled for the turns counter and the direction
to work properly for both the DOS console and the Windows GUI.
Encoder (A quad B) resolution must be of equal or lesser value than
the resolution set on the card. For example, if the resolution set on
the card is 14 bits, the A quad B resolution must be set to 14 bits or
less (not 16 bits).
SET OSCILLATOR FREQUENCY
1) Enter (8) to change frequency.
2) To change the Oscillator frequency, enter the bit multiplier. The bit
multiplier, which is an integer, is determined by the following formula:
Frequency = (bit multiplier) X (Hz/bit)
