Radiocrafts Embedded Wireless Solutions RC-IESM-Series Quick Start Guide How do I set up a simple link between an IESM board and a matching Radiocrafts RF module? A basic communication test can be done by sending and receiving serial data via the external RS232 (UART1) on the Sierra Wireless modem to and from a Radiocrafts Demonstration Board, after downloading the Radio Test Gateway (RTG) - demonstration software into the modem and enabling serial-to-serial mode.

Radiocrafts Embedded Wireless Solutions RC-IESM-Series Product Description The RC-IESM (Internal Expansion Socket Module) series of expansion cards for the Sierra Wireless AirLink Fastrack Xtend FXT modems (hereafter named Xtend only) contains an RF module which interfaces to the UART serial bus inside the modem, and an SMA connector for the external antenna. The RF module is a Wireless M-Bus module, a ZigBee module, or any module from the RC232 protocol family from Radiocrafts.

Radiocrafts Embedded Wireless Solutions RC-IESM-Series Functional Layout The ARM9 processor connects to the IESM board via a 50-pin GPC, General Purpose Connector, mounted on the secondary side of the board. The antenna connector is a standard SMA connector. Figure 2: IESM board functional connection Antenna connection A quarter wave antenna can be directly connected to the SMA antenna connector.

Radiocrafts Embedded Wireless Solutions RC-IESM-Series Data from UART1 via UART2 for module configuration and communication For detailed instructions on how to handle I/O’s on the GPC connector and for changing UART1 and UART2 Baud rates and handshake, see the RTG User Manual. Common to all IESM-boards: - UART2 default settings are 19200 Baud, no parity, 1 start and stop bit, no handshake.

Radiocrafts Embedded Wireless Solutions RC-IESM-Series Terminal Line Figure 3: RC232-CCT Window Handshake enable: - Enable CTS and/or RTS in configuration memory as described in module datasheet - Ensure that R49 and R50 (0 ohm 0603 size) are mounted on IESM board. One or both are by intention not soldered in production to avoid unintentional sleep mode (see module datasheet) - Ensure that R51 is not mounted, or de-solder if mounted.

Radiocrafts Embedded Wireless Solutions RC-IESM-Series The MBUS-DEMO can directly communicate with MBUS-IESM boards and handles ‘0x00’command inside the tool. Especially useful is the packet sniffer tab and after enabling RSSI in the setup tab: Incoming wireless M-Bus packages can then directly be monitored with its signal strengths. See MBUS-DEMO User Manual for details.

Radiocrafts Embedded Wireless Solutions RC-IESM-Series ZNM protocol modules. See the related document RC2400(HP)-ZNM Demonstration Kit Quick Start (including ZNMCCT User Manual) for a detailed description on how to use the PC Tools from Radiocrafts for configuration and communication with the module with the embedded ZNM protocol.

Radiocrafts Embedded Wireless Solutions RC-IESM-Series RC-IESM Circuit Diagram The circuit diagram of the RC-IESM board is shown in figure 6. A full resolution schematic is found in RC_IESM_2_0.zip available from Radiocrafts’ webpage. Figure 6: RC-IESM Circuit diagram RC-IESM PCB and Assembly layout The PCB is a simple 2-layer board where Layer 2 is used as ground plane. The laminate used is standard FR-4 board material. The PCB is 1.0 mm thick.

Radiocrafts Embedded Wireless Solutions RC-IESM-Series RC-IESM Bill of Materials The circuit diagram includes all components of the RC-IESM. Note that RC11xx, RC12x0/2x00 and RC2400 all requires different component mounting. Details are listed in the following tables. Components not to be mounted are marked DNM (Do Not Mount) in the ‘Quantity’ column.
