RC17xxHP-RC232
Ultra Narrow Band High Power RF Module at
169/433/444/458/463/467/868 MHz
Product Description
The RC17xxHP are a family of compact surface-mounted modules that measure only 12.7 x
25.4 x 3.3 mm.
The module contains a communication controller with embedded RC232 software
and is
pre-certified for operation under the European regulations (for applicable bands).
Custom variants can be offered in dedicated bands within the 169 - 870 MHz frequency
range. How to use the embedded RC232 protocol is described in the RC17xxHP-RC232 User
Manual.

Typical application Circuit:
Note that the VCC_PA pin supply the internal power amplifier only, while the rest of the
internal block runs on VCC. They can be connected together or separated using individual
supply. If VCC_PA is connected together with VCC, the max output power is reduced to +24
dB for all modules except RC1701HP that support +27 dBm at VCC_PA = 3.3 V. For all low
power variant the VCC_PA pin can be left open.
Quick Introduction to the RC232 embedded protocol
How do I transmit data?
Send your data to the RXD pin on the module. Use the UART format with settings (19200, 8,
1, N, no flow control). Up to 127 of payload bytes are buffered in the module. The module will
transmit the data when
•
the max packet length is reached
•
the unique end character is sent
•
the modem timeout limit is reached
The packet length, end character and timeout limit are configurable in-circuit.
How do I receive data?
Any received data packet with correct address and check sum will be sent on the TXD pin
using the same UART format as for transmit.

What about the antenna?
In most cases a simple quarter wavelength wire or a PCB track will do. Connect a piece of
wire to the RF pin with length corresponding to the quarter of a wavelength. For space limited
products, contact Radiocrafts and we will recommend the best antenna solution for your
application.
How do I change the RF channel or any other parameter?
To change configurable parameters, assert the CONFIG pin, and send the command string
using the same serial interface as for transmitting data. Parameters can be changed
permanently and stored in non-volatile memory in the module.
RC232™ Embedded Protocol
The module offers a buffered packet radio in the RC232™ embedded protocol. Using the
buffered packet radio mode, all data to be sent is stored in the module before they are
transmitted by the RF circuitry. Likewise, when data is received they are stored in the module
before they are sent to the host. This allows the communication controller to add address
information and to do error check of the data. In buffered mode the UART interface is used to
communicate with the host.
The embedded protocol, configuration commands and configuration memory is described in
the RC17xxHP-RC232 User Manual. This protocol is used in a wide range of RF modules
available from Radiocrafts. Please refer to the latest revision of the RC232 User Manual for
feature details.

The use of RF frequencies, maximum allowed RF power and duty-cycles are limited by
national regulations. The RC17xxHP-RC232 and RC17xx-RC232 are complying with the
applicable directives within the European Union when used within these limitations.
Note: Max output power (+27 dBm) @ 868 MHz are in EU limited by ERC/REC 70-03 to
operate in sub band 869.40 – 869.65 MHz. RC1780HP has 10 high power channels (ch 57-
66) inside this sub band that allow max output power (+27 dBm).
