Safety Precautions The following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating HMS1. Manufacturers of the cellular terminal are advised to convey the following safety information to users and operating personnel and to incorporate these guidelines into all manuals supplied with the product.
HMS1 Hardware Interface Description Confidential / Preliminary SOS s IMPORTANT! Cellular terminals or mobiles operate using radio signals and cellular networks. Because of this, connection cannot be guaranteed at all times under all conditions. Therefore, you should never rely solely upon any wireless device for essential communications, for example emergency calls.

HMS1 Hardware Interface Description Confidential / Preliminary 3. s Application Interface HMS1 is equipped with an 80 pin board-to-board connector that connects to the external application. The host interface incorporates several sub-interfaces described in the following chapters: • • • • • Operation Modes - see Section 3.1 Power supply - see Section 3.2 SIM interface - see Section 3.6 Serial interface USB - see Section 3.7.
s HMS1 Hardware Interface Description Confidential / Preliminary 3.1. Operating Modes The table below briefly summarizes the various operating modes referred to in the following chapters. Table 5: Overview of operating modes Normal operation GSM / GPRS SLEEP POWER DOWN HMS1_HD_V01.62 Tbd. GSM IDLE Software is active. Once registered to the GSM network, paging with BTS is carried out. The module is ready to send and receive. GSM DATA Connection between two subscribers is in progress.
HMS1 Hardware Interface Description Confidential / Preliminary s 3.2. Power Supply HMS1 needs to be connected to a power supply at the B2B connector (5 pins each BATT+ and GND). The power supply of HMS1 has to be a single voltage source at BATT+. It must be able to provide the peak current during the GSM uplink transmission. All the key functions for supplying power to the device are handled by the power management section of the analog controller.
s HMS1 Hardware Interface Description Confidential / Preliminary Example: If the length of the flex cable reaches the maximum length of 100mm, this connection may cause, for example, a resistance of 30mΩ in the BATT+ line and 30mΩ in the GND line. As a result, a 2A transmit burst would add up to a total voltage drop of 120mV.
HMS1 Hardware Interface Description Confidential / Preliminary s 3.4. Power Saving Intended for power saving, SLEEP mode reduces the functionality of the HMS1 to a minimum and thus minimizes the current consumption. The different sleep modes will be specified later. 3.5. RTC Backup The internal Real Time Clock of HMS1 is supplied from a separate voltage regulator in the analog controller which is also active when HMS1 is in POWER DOWN status.
HMS1 Hardware Interface Description Confidential / Preliminary s 3.8. Control Signals Several control lines are signaling the states of the HMS1 module or control the module. These states are power down, stand by, paging, GSM voice call, GSM data call, UMTS voice call, UMTS data call or HSDPA connection. 3.8.1.PWR_IND Signal PWR_IND notifies the on/off state of the module. High state of PWR_IND indicates that the module is switched off.
HMS1 Hardware Interface Description Confidential / Preliminary 4. s Antenna Interface The RF interface has an impedance of 50Ω. HMS1 is capable of sustaining a total mismatch at the antenna connector or pad without any damage, even when transmitting at maximum RF power. The external antenna must be matched properly to achieve best performance regarding radiated power, DC-power consumption, modulation accuracy and harmonic suppression.

Absolute Maximum Ratings The absolute maximum ratings stated in Table 6 are stress ratings under any conditions. Stresses beyond any of these limits will cause permanent damage to HMS1. The power supply shall be compliant with the SELV safety standard defined in EN60950. The supply current must be limited according to Table 6.
