Reference, Installation, and Operations Manual Upgrading a Mark II to a Mark III
3-9000-743 Rev S June 2013
Gain 307
C.4.3 Gain
The Mark III signal gain values (GainA1...GainD2) and limits (GainLowLmt and GainHighLmt)
are read in hardware gain units. Daniel MeterLink converts the hardware gain units to decibels
(dB) for display purposes using the conversion equation:
Equation C-10 Mark III Gain Conversion Equation
The Mark III gain units differ from those used by the Mark II. Therefore, the Daniel MeterLink
configuration conversion does not convert the Mark II
GainLowLmt and GainHighLmt parameters.
The Mark III GainLowLmt and GainHighLmt data points should be at their default values (the
widest allowable gain limits) and are unmodified by the Daniel MeterLink configuration
conversion. These data points can be modified using the Daniel MeterLink

screen.
C.4.4 Batch update period and stack size
The Mark III batch update occurs at a fixed timed interval whereas the Mark II batch update
occurs after each
BatchSize firing sequences are completed.
For the Mark III, the batch update period is a function of the SpecBatchUpdtPeriod and
StackSize data points (as described in Section 6.1.3).
When using Daniel MeterLink to convert a Mark II configuration for use in a Mark III, the Mark II
BatchSize parameter is not converted. The Mark III SpecBatchUpdtPeriod should be at its
default value (standard update period of 1 sec) and is unmodified.
The Mark III does not support “stacking-by-chord.” The Mark II
StackSize parameter is converted
to the Mark III StackSize data point as follows:
StackSize
(Mark II)
StackSize
(Mark III)
0, 1, 128 or 129 1 (none)
2 or 130 2
4 or 132 4
8 or 136 8
