BIT SWITCHES

2. BIT SWITCHES

WARNING
Do not adjust a bit switch that is described as "Not used", as this may
cause the machine to malfunction or to operate in a manner that is not
accepted by local regulations. Such bits are for use only in other
areas, such as Japan.
Note: Default settings for bit switches are not listed in this manual. Refer to
the System Parameter List printed by the machine.

How to calculate the rx level listed on the TCR (Journal)
Example: V29 96 L 01 A0 00 00
The four-digit hexadecimal value (N) after "L" indicates the rx level.
The high byte is given first, followed by the low byte. Divide the decimal value of N by
-16 to get the rx level.
In the above example, the decimal value of N (= 01A0 [H]) is 416.
So, the actual rx level is 416/-16 = -26 dB

Do not change the settings.
1: Instead of the personal code, the following data are
listed on the TCR for each analog G3 communication.
e.g. V33 14 01 03 00 02
First number: Final modem type used
Second number: Final modem rate (for example, 14
means 14.4 kbps)
Third and fourth numbers: Line quality data. Either a
measure of the error rate or the rx level is printed,
depending on the bit 3 setting below. (An M on the
report indicates that it is error rate, and an L indicates
Rx level.) The left hand figure is the low byte and the
right hand figure is the high byte (refer to the following
note for how to read the rx level). If it is a measure of
the error rate; a larger number means more errors.
Fifth number (rx mode only): Total number of error
lines that occurred during non-ECM reception.
Sixth number (rx mode only): Total number of burst
error lines that occurred during non-ECM reception.
The fifth and sixth numbers are fixed at 00 for
transmission records and ECM reception records.
