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).
5. SYSTEM CONNECTOR INTERFACE Data Terminal Ready (DTR) DTR indicates that the DTE is ready to receive data. It also acts as a hardware ‘hang-up’, terminating calls when switched high. The signal is active low. You can define the exact behaviour of DTR with an AT command. Data Set Ready (DSR) DSR indicates that the DCE is ready to receive data. The signal is active low. Data Carrier Detect (DCD) DCD indicates that the DCE is receiving a valid carrier (data signal) when low.

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.
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.
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.
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.
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.
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.

INT selects power from the internal +3.6V DC supply. EXT selects power from the EXT VCC connector.
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 $XGLR DQG 3&0 Jumper Default Description ULD To OUT To enable analog audio microphone path ULD must be connected to OUT using the jumper. OUT To ULD To enable analog audio microphone path OUT must be connected to ULD using the jumper. DLD To IN To enable analog audio earpiece path DLD must be connected to IN using the jumper.

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.
14. USING THE DEVELOPER’S KIT 14.8 System Connector Pin Assignments Refer to the table below when monitoring signals on, or connecting to, X1. The table shows the system-connector pin assignments for the radio devices. See “System Connector Interface”, page 19for more details.
