SYSTEM CONNECTOR INTERFACE 5.9.3 Control Signals - RTS, CTS, DTR, DSR, DCD, RI UART1 control signals are active low and need a standard interface IC, such as the MAX3237, to generate standard RS232 levels. UART1 converted signals, together with DGND, RD and TD form a 9-pin RS232 data port. RTS and CTS are capable of transmitting at 1/10th of the data transmission speed for data rates up to 460 kbit/s (byte-oriented flow control mechanism).

8. HINTS FOR INTEGRATING THE RADIO DEVICE 8. Hints for Integrating the Radio Device This chapter gives you advice and helpful hints on how to integrate the radio device into your application from a hardware perspective. Please read and consider the information under the following headings before starting your integration work: • Safety advice and precautions. • Installation of the radio device. • Antenna. 8.1 Safety Advice and Precautions 8.1.
PAGE 55
8. HINTS FOR INTEGRATING THE RADIO DEVICE 8.1.2 SIM Card • Before handling the SIM card in your application, ensure that you are not charged with static electricity. Use proper precautions to avoid electrostatic discharges. The radio device must be switched off before the SIM card is installed in your application. • When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card holder.
PAGE 56
8. HINTS FOR INTEGRATING THE RADIO DEVICE 8.2 Installation of the Radio Device 8.2.1 Where to Install the Radio Device There are several conditions which need to be taken into consideration when designing your application as they might affect the radio device and its function. They are: Environmental Conditions The radio device must be installed so that the environmental conditions stated in the Technical Data chapter, such as temperature, humidity and vibration are satisfied.
PAGE 57
8. HINTS FOR INTEGRATING THE RADIO DEVICE • If you intend to use SMS in the application, ensure this is included in your (voice) subscription. • Consider the choice of the supplementary services described in section 2.3.2 Short Message Service, page 10. 8.2.2 How to Install the Radio Device Power Supply • Use a high-quality power supply cable with low resistance. This ensures that the voltages at the connector pins are within the allowed range, even during the maximum peak current.
PAGE 58
8. HINTS FOR INTEGRATING THE RADIO DEVICE 8.3 Antenna 8.3.1 General The antenna is the component in your system that maintains the radio link between the network and the radio device. Since the antenna transmits and receives electromagnetic energy, its efficient function will depend on: • the type of antenna (for example, circular or directional); • the placement of the antenna; • communication disturbances in the vicinity in which the antenna operates.
PAGE 59
8. HINTS FOR INTEGRATING THE RADIO DEVICE In general, CE-marked products for residential and commercial areas, and light industry can withstand a minimum of 3 V/m. 8.3.4 The Antenna Cable Use 50 Ω impedance low-loss cable and high-quality 50 Ω impedance connectors (frequency range up to 2 GHz) to avoid RF losses. Ensure that the antenna cable is as short as possible. The Voltage Standing-Wave Ratio (VSWR) may depend on the effectiveness of the antenna, cable and connectors.

14. USING THE DEVELOPER’S KIT Jumper Default Description DIS - When fitted, the serial port driver IC disables the receiver buffers that normally drive UART signals into the radio device. This will prevent the radio device from receiving data through the serial port. WAKE - When fitted, the radio device will automatically power-up when the UART DTR signal is driven high. This allows a convenient mechanism for an external host computer to switch on the module.

14. USING THE DEVELOPER’S KIT DCD Fitted Connects serial port control signal DCD between UART connector X4 and radio device. Note: DCD is a dual function signal from the radio device. When this signal is being used for any other purpose (e.g. Keypad or application specific through X2 or X3), this jumper must be removed. TD Fitted Connects serial port Transmit Data signal TD between UART connector X4 and radio device. Note: It is only valid to have one Transmit Data buffer in the circuit.

14. USING THE DEVELOPER’S KIT 14.4 Switches All switches are mounted on the front panel of the developer’s box. Switch Default Description Vcc (SW1) N/C This switch chooses the voltage source that the radio device will use. The default state N/C makes the voltage path to the radio device open circuit. Choosing INT connects the internal +3.6V DC supply to the VCC pins of the radio device. Choosing EXT connects the external +3.6V DC supply to the VCC pins of the radio device. Note: The external +3.

14. USING THE DEVELOPER’S KIT 14.5 Headers Header Connections Description PCM ULD, DLD, OUT, IN, SYN, CLK Carries digital audio PCM signals for access by user application. Note: In order for analog audio to be created internally by the radio device, signal ULD must be connected to OUT for the MIC path and signal DLD must be connected to IN for the EAR path. SIM VCC, RST, CLK, VPP, DAT, PR#, GND This connector allows access to the SIM interface signals.

14. USING THE DEVELOPER’S KIT 14.6 Connectors Connector Type Description RADIO DEVICE ‘X1’ 60 PinDual Row0.05” pitch The radio device is 'plugged-in' to the development kit. This allows direct connection of the module to the development board. APPLICATION ‘X2’ 40 PinDual Row0.1” pitch This 40-pin connector is compatible with standard 0.1" pitch mating connectors and with 0.05" pitch IDC ribbon cable connectors. This allows the user a range of connection methods to interface to the application.

14. USING THE DEVELOPER’S KIT Connector Type Description Handset ‘X6’ RJ9 socket Connector for a standard telephone handset. Carries signals from the balanced outputs BEARN and BEARP and to the balanced inputs MICN and MICP. To enable an analog audio link it is necessary to link PCM signals “ULD to OUT” and “DLD to IN” using jumper links on the PCM header. Note: The PCM links to enable analog audio are fitted by default but may have been removed during customer development.

14. USING THE DEVELOPER’S KIT Connector Type Description EXT VCC 3 pin Circular This connector carries three signals: EXT VCC (1); CHG_IN (3); GND (2). (These signals are wired into PCB holes labelled EXT, CHG, GND 1 2 respectively).EXT VCC must be a +3.6VDC source capable of 3 supplying up to 2.0A. This can be a battery source.CHG_IN can be a +5.0VDC source capable of supplying 600mA maximum.GND is the ground reference to be used by the external supplies.
