Please note the following:      Mounting holes positioned at two of the corners make it possible to securely bolt the modem into your application. Keypad, display, microphone, speaker and battery are not part of the modem. The SIM card is mounted in the modem, accessible by the user under a lid without any tools. The pins and electrical characteristics or the modem’s various connectors are described in “2. Electrical Description” Information about the antenna connector is found in “2.

3 Operation 3.1 Switching ON the modem There are two ways to switch on the modem, once power is applied.   assert TO_IN to high level for > 5s activate the RS232 control line DTR The modem is fully operational after 4 seconds. Logging onto a network may take longer than this and is outside the control of the modem. The modem can be configured to start up at the time power is applied by permanently tying power connector signals TO_IN (pin 4) and VCC (pin 1) together.
PAGE 16
3.2 Switching OFF the modem There are two ways to switch off (power down) the modem as described below:   use the AT#SHDN command; DTR permanently to low (0,8V) HR_IN to high level for t > 5s A delay of up to 10s is experienced as the modem logs off the network 3.3 Optional Low Power Mode In addition to turning the device completely off the terminal can placed into a low power mode while maintaining connectivity.

Switching off GPIO3 at#gpio=3,0,1 These LEDs can be controlled e.g. by an external microcontroller via at-commands issued to the terminal via the serial RS232 interface. They can be used for signalling any useful status of the external application such as:     error indication status of communication (GPRS, SMS, CSD, etc.

CEP AG may refuse warranty claims where evidence of product misuse is found. 3.7 SIM card precautions Before handling the SIM card in your application, ensure that you are not charged with static electricity. Use proper precautions to avoid electrostatic discharges. When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card holder. Caution! Do not touch these connectors! If you do, you may release an electrical discharge that could damage the modem or the SIM card.

4 Installation of the modem This chapter gives you advice and helpful hints on how to integrate the HT910 E Terminal into your application from a hardware perspective. Please read the information given in “Safety and Product Care”, page 10 and then read the information in this section before starting your integration work. 4.1 Where to install the modem There are several conditions which need to be taken into consideration when designing your application as they might affect the modem and its function.
PAGE 20
4.2 How to install the modem 4.2.1 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. When the unit is powered from a battery or a high current supply, connect a fast 1.25A fuse in line with the positive supply. This protects the power cabling and modem. 4.2.
PAGE 21
4.3.3 Antenna placement The antenna should be placed away from electronic devices or other antennas. The recommended minimum distance between adjacent antennas, operating in a similar radio frequency band, is at least 50cm. If signal strength is weak, it is useful to face a directional antenna at the closest radio base station. This can increase the strength of the signal received by the modem. The modem’s peak output power can reach 2W. RF field strength varies with antenna type and distance.
