Operating manual
This operation manual is intended to study the principle of op-
eration, correct use and maintenance of the radio receiver
"RTD Astra-Y" (firmware Y-UOP-v4_0 and higher) (Figure 1).
The manufacturer reserves the right to make changes in the
design, software, circuitry solutions and product configuration
that do not degrade its technical characteristics, do not violate
mandatory regulatory requirements, without prior notice to the
consumer.

Purpose
1.1
RTD is designed to receive over the radio channel notifi-
cations from registered TTDs, decode and send notifications to
three built-in LED indicators, two signal relays and one OC
output, as well as via the LIN interface in standalone operating
mode or via the RS-485 interface in extended operating mode.
1.2
The main purpose is the organization of centralized moni-
toring via radio channel (433 MHz) of cottage settlements, in-
dustrial facilities, etc.
1.3
The radio channel communication between the RTD and
the TTD is two-way.
1.4
RTD supports up to 48 of TTD in
standalone operating mode and up to 250 of
TTD in extended operating mode.
1.5
RTD supports working in
standalone
mode
without connected Astra-Y MP.
1.6
Remote indication panel unit Astra-861
can be connected to the RTD in standalone
mode via the LIN interface.
1.7
RTD supports working in extended
mode, connecting via RS-485 interface to the
Astra-Y MP or to a PC with installed software
ARM-Y through connector F7. To connect to
a PC, the Astra-984 interface unit is used.
1.8
RTD supports two-level retransmission
of the signal and tracks the routes of signals through TTD re-
peaters. Current routes can be viewed using the ARM-Y soft-
ware in the configuration mode.
