Telemetry; Installing The Ar637T Receiver - Spektrum SPMAR637T Manual

Telemetry

The AR637T features full range telemetry and will provide receiver battery
voltage, flight log data, and variometer* and altitude* data without any
additional sensors. Additional telemetry devices such as voltage sensors can
be connected to the volt port, and XBus telemetry sensors can be connected
through the XBus connector. Every XBus telemetry device has two XBus ports,
and XBus telemetry sensors can be connected in a daisy chain in any order.
*TIP: AR637TA receivers included with BNF models do not have a
built-in pressure sensor for altitude and vertical speed data (variometer)
measurements. If you want to add altitude and variometer to an AR637TA, an
external sensor (SPMA9589) can be connected to the XBus system.
The AR637T is not compatible with the Spektrum Temperature Sensor (SPMA9571)

Installing the AR637T Receiver

1.
Mount the receiver using double-sided servo tape. The receiver may be
mounted upright, upside down or on its side, but it should be square with
the fuselage in its mounting position. The receiver cannot be mounted at
an odd angle.
TIP: For SAFE setups, install the receiver as close to the center of gravity of
the aircraft as practical.
2.
Connect the servos to their respective ports on the receiver using the chart
below.
CAUTION:
Always perform a control surface check and AS3X control surface
response test before flying a new setup, or after any setup changes.

IMPORTANT:
When using Y-harness or servo extensions with Spektrum
equipment, do not use reversing harnesses. Using reversing Y-harnesses or
servo extensions may cause servos to operate erratically or not function at all.
Incorrect installation of the receiver could cause a crash.
