9.8 Error counter
The receiver features two separate error counters: one for low-
voltage errors, one for signal errors.
The corresponding LED on the receiver (
sum of the seconds during which errors were detected:
BATT-ERR: indicates recorded low-voltage errors.
SIGNAL-ERR: indicates recorded signal errors.
If errors are indicated, they can be saved (stored) after the
landing using the SET button (
( 12.).
1. Operating voltage errors
Examples: flat or faulty battery, inadequate cable cross-
section, etc.
The error count contains all voltage collapses below the
threshold of 4.5 V (value can be changed using the MULTI-
mate or RX DataManager
2. Signal errors
The count contains instances of interference to the M-LINK
signal packet. For example, interference could be due to
unfavourable aerial deployment, signal clashes, or operating
the system close to the range limit.
Signal errors are recorded in virtually every flight. In most
cases the pilot does not notice them, but they are still picked
up by the extremely sensitive error counter.
After a few flights, and regular analysis of the error counter, you
will gain the experience to detect changes in good time, and to
identify possible causes of interference.
! Protracted voltage collapses below 3.5 V cause the receiver
to re-boot. If this occurs, the values for both error counters are
lost permanently.
! If you press the SET button for the purpose of saving the
error count, the stored information is retained until the next time
you save the error count.

ELEMETRY
The telemetry-capable RX-9/12/16-DR pro M-LINK 2.4 GHz re-
ceivers offer a means of transmitting data from the model back
to the transmitter.
When these receivers are employed, the telemetric values for
"receiver battery voltage" and "connection quality" (LQI = Link
Quality Indication) are transmitted directly, i.e. they require no
additional external sensors.
The receivers can also be used in conjunction with up to sixteen
external M-LINK sensors, which are connected in series (in any
order) to the socket or sockets marked "S". In this way a very
wide variety of telemetry data can be "sent back" to the pilot.
! Note:
The possible methods of indicating telemetry data by visual
and / or audible means vary according to the M-LINK trans-
mitter or RF module in use.
Examples of external M-LINK sensors are as follows:
Voltage sensor (# 8 5400).
Temperature sensor (# 8 5402).
Current sensor:
Max. 100 A (# 8 5401) or max. 35 / 60 A (# 8 5403).
Rev count sensor:
Optical (# 8 5414) or magnetic (# 8 5415).
Vario / altitude sensor (# 8 5416).
For more information on connecting and operating the various
sensor types and their features (measurement range, addres-
sing, warning threshold settings, display facilities for minimum,
average or maximum values, in some cases activation of a
second measurement channel, ...) please refer to the instructions
supplied with the sensors and / or the MULTImate.

WO ECEIVER
MULTIPLEX RX-9/12/16-DR pro M-LINK receivers are what are
known as "dual receivers", ("DR"): each receiver case contains
two complete receiving circuits operating in parallel ("receiver
diversity"). It is also possible to connect two receivers together
using the Diversity lead (# 8 5070). In this configuration a total of
four receiving circuits is operating in parallel:
All four receiving circuits installed in the two receiver cases pick
up and assess the signals ("quadruple diversity"). In this section
we refer to this type of diversity as "two-receiver mode".
Two-receiver mode is possible with various MULTIPLEX M-LINK
receivers starting with the RX-7-DR M-LINK. You can also connect
different M-LINK receiver types together, provided that both are
capable of two-receiver operation (e.g. 1 x RX-16-DR pro M-LINK
and 1 x RX-7-DR M-LINK).
The different orientation of all four receiver aerials provides a
further improvement in the reception performance, since this
arrangement minimises the directional aerial effect. This means
that one receiver aerial always has a good "view" of the trans-
mitter regardless of the model's attitude. Two-receiver mode
therefore provides an additional safety margin. Two-receiver
mode is particularly recommended for use in large-scale model
aircraft.
