RC11xx-RC232
Low Cost Multi-Channel RF Transceiver Module
Product Description
The RC11XX-RC232 RF Transceiver Modules are compact surface-mounted high performance
modules for FSK operation with embedded protocol. The modules are completely shielded and
pre-certified for operation under the European radio regulations for license-free use.
RC1170- and RC1190-RC232 conforms with regulations for operation under FCC (USA and
Canada) and under the directives given by G.S.R. (India) respectively.
Applications
• Wireless Sensor Networks
• Automatic Meter Reading
• Alarm and security systems
• Point-of-sales terminals
• Bar code scanners
• Telemetry stations
• Fleet management
Features
• Small size (12.7 x 25.4 x 3.3 mm), shielded and optimized for SMD mounting
• Low sleep current consumption, well suited for battery operated equipment
• Embedded RC232™ protocol with Addressing and Error check
• Up to 1018 byte data buffer
• Two-wire UART interface for easy RS232/422/485www.DataSheet.co.kr wire replacement (handshake optional)
• No external components
• No configuration required for single-channel use
• Easy to use data interface
• Wide supply voltage range, 2.0 – 3.9 V
• RC1140/80-RC232 conforms with EU R&TTE directive (EN 300 220, EN 301 489, EN 60950)
• RC1190-RC232 conforms with regulations for operation under FCC CFR 47 part 15
• RC1170-RC232 complies with G.S.R.564(E) (G.S.R.168(E)).

on the UART
tTXD = # bytes received x 590 us/char (10 bits at 19.2 kBd + 70 us

Time from last character is received by the UART (including any
timeout) until CTS is activated
Time from last character is received by the UART (including any

Delay after channel-byte is sent until prompt (“>”). (For other
commands like ’M’, ’T’ there is no delay but immediate prompt)
In this period the internal flash is programmed. Do not reset, turn the
module off, or allow any power supply dips in this period as it may
cause permanent error in the Flash configuration memory. After 0xFF
the host should wait for the ‘>’ prompt before any further action is
done to ensure correct re-configuration.
tTX = # bytes to send x 1.67 ms/byte (at 4.8 kbit/s) + 7 bytes preamble,
sync and length + 2 bytes address + 2 bytes CRC
Time from end of S command to start of RSSI byte received on UART

RC11xx-RC232
The simplest antenna to use is the quarter wave whip antenna. A quarter wave whip antenna
above a ground plane yields 37 Ohm impedance and a matching circuit for 50 Ohm are usually
not required.
A PCB antenna can be made as a copper track where the ground plane is removed on the back
side. The rest of the PCB board should have a ground plane as large as possible, preferably as
large as the antenna itself, to make it act as a counterweight to the antenna. If the track is shorter
than a quarter of a wavelength, the antenna should be matched to 50 ohms.
The lengths of a quarter wave antenna for different operational frequencies are given in the table
below.
