QPT-HT / RCM 2 Introduction HERMES 2.1.1 Intended usage The project name HERMES has the meaning “Hardware for Enhanced Remote-, Mobility- & Emergency Services” and thus describes the main features of this device. This unit was designed for automotive usage and contains the following features: GSM, UMTS, LTE , USB, Bluetooth, Wireless LAN. It provides different telematic services and is the interface between different types of Daimler car headunits and the public network.
QPT-HT / RCM 3 System Description 3.1.1 System features In the past Daimler had already PASS v3.
QPT-HT / RCM 3.1.2 Hermes Block Diagram The following diagram shows the HERMES PASS 4G unit. The main functionalities of this box are: 1) Providing Network access for different telematic services 2) Providing E-Call (Emergency Call), R-Call (Road Service Call), I-Call (Information Call) The network access will be realised by connecting a headunit over USB, BT or WLAN to the HERMES Pass4G unit. Regarding Bluetooth the unit only supports the Bluetooth DUN profile according IEEE 802.15.
QPT-HT / RCM To cover different target markets the HERMES unit provides four different NAD-modules. These are: - ME909Tu-120 (ECE LTE => M055) - MU809Tu-8 (ECE UMTS => M090) - ME909Tu-565 (USA => M088) - ME909Tu-820 (China => M087) This HERMES provides different interfaces. For the car passenger there are only the E/R/I-Call buttons visible. To the car it is connected over CAN intervaces (CAN-D/CAN-H). Beside of that there are several UART and USB interfaces for debugging purpose.
QPT-HT / RCM 3.1.4 Operating States The following picture shows the possible HERMES operating states – these are: Full Sleep mode, Normal Power mode, DNO mode, Normal Polling mode, Extended polling mode 3.1.
QPT-HT / RCM 3.1.6 BT/WLAN Interface The HERMES PASS 4G module includes Bluetooth (IEEE 802.15) and WLAN (IEEE 802.11a/b/g/n) technology for connecting different types of Daimler headunits over GSM/UMTS/LTE to public network. The unit can use either Bluetooth or WLAN as transition medium. It is not possible to use both at the same time! The BT/WLAN functionality was realized by using the Harman CWM-03 module. This module has the following block diagram: BT/WLAN-Module The module supports IEEE 802.
