CODE 44 - RATE B MINIMUM/MAXIMUM UPDATE TIME
The determination of the rate value uses a method in which the elapsed time is
measured between the first and last pulse of the update period. The minimum
update time is the shortest the time period can be. Once the minimum update time
has expired, the unit will end the measurement period when the next negative
going count edge occurs. If the unit does not receive the next negative count edge
within the maximum update time at the start of the measurement period, the unit
will end the time period and the rate display will go to zero. At very slow count
rates the update time period will be the actual period of one count cycle.

CODE 45 - RATE B SCALE MULTIPLIER
The Rate B Scale Multiplier is used in conjunction with the Rate Scale Factor
B and Rate B Conversion Factor to scale the actual signal input to obtain the
desired reading.

CODE 46 - RATE B DECIMAL POINT & LEADING ZERO
BLANKING
There are six basic modes of decimal point placement for the Rate B indicator
of the Gemini 5200. The decimal point is placed to the right of the display digit
that corresponds to the mode identifier. (The right most decimal point, digit 1, is
never turned on.) A “-” sign in front of the mode identifier will inhibit leading
zero blanking. The absence of a “-” sign will enable leading zero blanking.

CODE 51 - OUTPUT ASSIGNMENT
The outputs of the Gemini 5200 can be assigned to either the Rate A or Rate B
channel or one to each.
The Gemini 5200 has a Preset tracking feature which allows Preset 1 to track
Preset 2. If Preset tracking is programmed, whenever the Preset 2 value is changed,
the Preset 1 value will also change to maintain the same offset. For example, if
Preset 1 is 100 and Preset 2 is 200, changing Preset 2 to 300 will automatically
change Preset 1 to 200, maintaining the same 100 unit offset. In order to change the
amount of offset, the Preset 1 value is changed. The Preset tracking feature is
programmed by adding a “-” modifier in front of the desired mode.
Note: When Preset tracking is enabled, before changing Preset 2 via serial
communications, the Preset 2 value must be interrogated in order to establish
the Preset 1 value.
[51 1] Output 1 assigned to Rate A, Output 2 assigned to Rate B
[51 2] Outputs 1 & 2 assigned to Rate B
[51 3] Outputs 1 & 2 assigned to Rate A
[51 -1]
[51 -2]
These modes are the same as above with the exception
[51 -3]
that Preset Tracking is enabled.
