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 10pin 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

IRAM Back-End
POLAR SWITCH user manual
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

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:
•

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.
