3. Introduction

The aim of the POLAR SWITCH1 module is to select, for each antenna, what horizontal or vertical polarisation data is to be sent to the correlators. The module can process 12 antenna and is fully compatible with NOEMA12.

The digital board receives commands through the CAN3 bus, a micro-controller (MCU12) translates them and drives the switches through two connectors. The switching is synchronised by the 1pps12 pulse issued from the observatory master clock.

Last switching position, power supply voltages, temperature and IDentification information can be monitored with few CAN12 commands.

4. General Specifications

4.1 Background

The digital board carries the 1pps12 receiver and 4 drivers, the 5MHz clock receiver and 4 drivers, connectors and voltage regulators on the motherboard, and a C1646 micro-controller (MCU) located on a daughter board.

The interface between the CAN bus and the switches is a commercial daughter board with a C164 micro-controller (MCU). It is a derivative of the famous Infineon C1678 family. It receives commands through the CAN bus, computes data and translates them in switching commands. Interruption routines process CAN receive and the timing management. Switching update is synchronised by the 1pps12 timing signal. The MCU can be reset by a local pushbutton located on the mother printed circuit board.

On the front panel are located the CAN connectors, indicators and switch connectors.

On the rear panel are located the 230VAC connector and main switch, the 5MHz and the 1pps connectors used to feed WIDEX.

6. Instrument Interfaces

6.1 CAN bus I/O Signals

The DB9 sockets C1&C2 connect the module to the external CAN bus3 network. CAN_L & CAN_H feed a CAN transceiver (PCA82C251) located on the MCU daughter board. The CAN controller is embedded inside the MCU C164.

6.2 1pps Sync interface

The 1pps Timing signal is delivered in coaxial through the C6 connector described in paragraph 5. A NC7S1414 trigger receiver feeds four drivers whose outputs go to the connectors C7 up to C10. The 1pps12 timing signal also feeds a fast interrupt input of the MCU to synchronize the events that takes place in the module.

6.3 Reset button

The Reset button is located on the left side of the front panel. The Reset signal feeds the Master Reset of the C164 MCU. It is used to re-initialize the MCU.

6.4 RS232 Serial Port

The RS232 port is connected to a MAX233013, transceiver and levels translator, before feeding the asynchronous serial channel #0 of the MCU. This port is used to download the user software into the flash RAM. The HE10 socket J2, described in paragraph 5.5 table 2, is dedicated to maintenance and software upgrade. The 3M 10-pin connector J2 is only reachable when the module is open.

6.5 5MHz reference clock

The 5MHz reference clock input delivered in coaxial through the C11 connector, AC coupled in single mode with 0dBm level, feeds a LT171912 comparator. Its output feeds four inverters whose outputs go to the connectors C12 up to C15.

7. Local Interfaces

7.1 One Wire interface

Each motherboard has a unique serial ID number generated by a Dallas Semiconductor DS18S2011 device, which offers a temperature sensor in addition. The serial ID number is delivered in 48-bit format (6 bytes) and temperature in 9 bits format (2 bytes). For maintenance purpose, module temperature and ID number can be requested with CAN commands.

7.2 Analog Voltages Monitoring

The MCU includes an on-chip 8-channel Analog to Digital Converter with 10-bit resolution. Four output voltages are monitored: +5V, +3.3V, M5V, P5V and an input



voltage: +6.5V. For maintenance purpose, voltages reading can be requested with few CAN commands.

8. Implementation Details

8.1 Micro Controller Unit (MCU)

The MCU is a DIPmodul-1644 from SYSTEC used as a daughter board. It carries a C164 µicrocontroller running at 20MHz with a 10MHz quartz, 128 KB of FLASH memory, 32 KB of SRAM, 2 KB of serial EEPROM, 8 dipswitches and a CAN transceiver. A single +5V / 80mA power supply is required. According to SYSTEC, its MTBF is 1,307,950 hours or 149 years. 8.1.1 C164 Micro-Controller Unit (MCU)

The micro-controller is a C1646, a 16-bit processor from INFINEON. It is a derivative of the C1678 family in an 80-pin TQFP package. It combines high CPU performance (up to 10 MIPS) with high peripheral functionality: full CAN interface, 8-input ADC, asynchronous serial port, High Speed synchronous serial port, timers, RTC12, 14 digital I/Os available to user and high speed DMA under interruption. A bootstrap loader is available to download user software into Flash memory. For more information, refer to the datasheet listed at the end the document4.

8.1.2 CAN Controller The micro-controller has an on-chip CAN controller (Rev. 2.0B) with 15 message objects. It is capable of 1-Mbaud operations.

8.1.3 Analog to Digital Converter The micro-controller has an 8-channel Analog to Digital Converter with 10-bit resolution. A conversion can take place in less than 10 microseconds. Any unused channel can be used as an extra conventional digital input.



8.1.4 Digital I/O The micro-controller has up to 59 general purpose I/Os among which 14 are available outside of the daughter board. This is enough for our application.

8.1.5 Asynchronous Serial Controller The micro-controller has a single serial channel dedicated to the RS232 interface. This interface is used to download user software.

8.1.6 Synchronous Serial Controller The micro-controller has a high-speed synchronous serial channel capable of 5-Mbaud operations. It can be used for: I2C, SPI or any serial transmission. In this module, it is dedicated to communicate with an EEPROM and is not available on external pins.

8.1.7 One Wire controller One-Wire interfacing has easily been developed in C for this micro-controller. This interface use one pin and is dedicated to DALLAS integrated circuits.

8.2 Voltage regulators A DC/DC converter and three low drop voltage regulators are used in this module. Fed by +6.5V, the four regulators deliver:

• M5.0V/ 480mA for the switches • P5.0V / 720mA for the switches • +3.3V / 20mA for the 1pps interface • +5.0V / 100mA for the ICs

9. Built-in Firmware

9.1 Bootstrap loader

A bootstrap loader is available to download user software. By simultaneously pressing RESET and BOOT then release first RESET, and 3 seconds later release BOOT. Now the MCU is ready to accept user software from the RS232 line. Run Flashtools16W on any PC to download the firmware into the FLASH memory. At the end of the download process, pressing RESET will initialise the program.

9.2 Power up or Reset sequence At init, receivers with horizontal polarisation are selected to feed the correlators.



10. Device-Specific Software / CAN Functions Interface

10.1 Operating program In normal operation, the module receives Can frames with next polarisation settings for the antennas 1 up to 12. The 1pps pulse synchronizes all changes.

10.2 CAN Overview The POLAR SWITCH module is controlled and monitored by the PdB2 CAN network, revision 2.0B (extended format), operating at 1Mbauds. The module is a slave CAN node operating in the address range 0x0828 0000 (hex), through 0x082C 0000 (hex). Its CAN relative address space spans from 0x0 0000 to 0x3 FFFF (hex). 8 switches located on the MCU daughter board define the module global address. Each switch being a power of 2, the result ranging from 0 up to 255 is multiplied by 0x4 0000 (hex) to generate the module global address. When a broadcast message 0 is received, the module transmits its address. CAN payload bytes are listed from 1 up to 8.

Address range 0x0828 0000 0x082B FFFF (hex) Relative address 0x0000 0000 0x0003 FFFF (hex)

Note: L1 indicator flashes when a CAN frame is received or transmitted.
