disableoverflow

Disables the overflow indication.

disableunscaled

If the ‘Scale’ reed switch is enabled by the hardware link ‘link C’ or by software, issuing this

command will prevent Scale Swapping function from affecting the count.

disablezero

If the ‘Zero’ reed switch is enabled by the hardware link ‘link B’ or by software, issuing this

command will prevent the zero function from affecting the count.

display1

Directs the system to display the value derived from the number of counts registered from (non-

quadrature) input 1

display2

Directs the system to display the value derived from the number of counts registered from (non-

quadrature) input 2.

displayq

Directs the system to display the value derived from the number of counts registered from the

quadrature input comprising of both inputs 1 & 2.

dwelltime

Input a dwell time – adjusts the time that the display remains illuminated after light is

extinguished, in seconds – 1255 seconds maximum.

enable232zero

This command disables the “RS232 DATA LOOP BACK ZERO” function. The RS232 data output

from pin 1 (5 way connector) is fed back into the data input pin 2 and a comparison carried out. If

there is no difference between them (which is to be expected), then the Zeroing of the Display

commences.

enableabs0

This command enables the display of absolute zero or ‘TDC’ (Top Dead Centre).

enablelightsensor

If the Light Sensor is not enabled by the hardware link ‘link A’, issuing this command will enable

the Light Sensor which will allow the unit to enter a very low power mode when the presence of

light is not detected.

enableoverflow

Enables indication of an overflow.

enableunscaled

If the ‘Scale’ reed switch is not enabled by the hardware link ‘link C’, issuing this command will

enable the Scale Swapping function for when the reed is in close proximity of a magnetic field.

enablezero

If the ‘Zero’ reed switch is not enabled by the hardware link ‘link B’, issuing this command will

enable the zero function when the reed is in close proximity of a magnetic field.

excite

Keep the bridge on

loaddisp

Load accumulator

normal

‘normal’ defeats any or all tests in progress and returns the system to ‘normal’ operation.
