Setup Guide
The EMCOR module is properly configured for use before shipment. The following jumper
configuration guide is for reference only and shows how the module should be configured for normal
use. All testing is performed with the jumpers in the following configuration. Table 1 shows the signal
names and jumper configurations. Figure 1 shows the actual location of the jumpers on the module.
The table below does not reference the jumper on P9, which is installed to ensure a predictable CPU
boot-up process.
The EMCOR module comes equipped with a CPU module attached (non SLAC customers only). The
CPU must go through a boot up process each time power is applied to the crate before the EMCOR
module can be used to control MCOR modules, unless the USB Diagnostic Application is being used.
Instructions for the CPU boot up process, which loads the OS into the CPU module, can be found later
in this document.
Note that due to the amount of heat generated by the CPU module, it is necessary to always make
certain that a blower assembly is installed to the crate and that air flow is constantly available across
the EMCOR and CPU module as a means to remove heat being generated.

EMCOR Controller Module Description
The EMCOR module was designed to replace the Interface Controller module that resides in slot 00 of
the crate power supply. The EMCOR module will only fit in slot 00 since that is the only location in
the crate with the 2 connectors (P1 and P2) necessary to mate with the EMCOR module. The EMCOR
module will receive the required power needed from the crate power supply via crate connection P1
and EMCOR module connection J2. The EMCOR module will control up to 16 MCOR modules using
a GUI based software such as EPICS and the EMCOR front panel EPICS CA port.

Note that all of the signal connections for the EMCOR module J1 are identical to the Interface
Controller module J2 connector, but many of the EMCOR J2 connections are not the same as the
Interface Control module J1 connections. The signal names for the EMCOR connections (J1 and J2) are
shown in table 2 below.
Caution: Crate connections J and J4 on the back of the crate were designed for use with the C4
Interface Controller, and NOT the EMCOR Controller. Do not make connections to either J or J4 if
you are going to be using the EMCOR controller, as damage to the controller or external connections
could occur. Table has been created as a means to map the EMCOR J2 connections to the crate J and
J4 connections.

EXT INTLK connection 1 Description
Crate connection J1, which is a BNC connector on the back of the crate labeled "EXT INTLK", must
be configured correctly for normal operation of the crate. As is currently the case with the Interface
Controller module, a closed switch must be present across J1 or an MCOR fault will be generated.
The signal name for this connection is 'Water_Sum_Fault'. An open switch will cause +5V on the
water_sum_fault circuits which will generate a fault condition and disable all MCOR modules.
Crate OK connection 2 Description
When properly configured this BNC connection may be used as a dry contact output to enable/disable a
properly configured Bulk Power Supply output.
A properly equipped power supply used as the bulk supply must have a connection available that will
enable the output of the supply with a short across the applicable pins. Consult the operator's manual
of the power supply in use for more specific information.
Event Receiver (EVR)
Currently these functions have not yet been implemented.
Fast Feedback
Currently the Fast Feedback function has not yet been developed.
EMCOR Crate Diagnostic Application
This is a Windows based GUI application primarily used as a diagnostic application to monitor and
reset certain faults, set and monitor MCOR channels, and turn on/off a properly configured bulk power
supply. A USB male Type A connection attached to a PC with a USB male Type B connection attached
to EMCOR connector J9 is required for use with this application.
The application may be used as soon as the crate has been powered up and can be used whether the
CPU boot process has been completed or not. If the CPU boot up process is not going to be performed,
both the serial and Ethernet cables (J7 and J5) do not need to be connected. Once the crate is powered
up and the power-up sequence of the EMCOR module has completed, a green (OK) LED on the
EMCOR module should be slowly flashing. A red LED on the MCOR module(s) may also be flashing
(assumes that the bulk supply is connected and enabled, and a closed switch across the crate J1

connector) which would indicate a fault on the MCOR module(s).
The application may now be opened and the main panel shown in screen shot 1 will appear.
To remove the fault(s) associated with any MCOR modules during the power up sequence, (assuming
there are any) click on the 'Faults' tab on the main panel. The 'Faults' panel will open up (screen shot
2). After the 'Refresh' tab of the 'Faults' panel is clicked, all faults associated with the MCOR modules
will show up in red ( a fault indication on this screen will correspond to a flashing red LED on the
indicated channel MCOR module). In screen shot 2 only one module is showing in red since the crate
is only populated with one MCOR module (channel 7). The fault can be cleared by checking the
'MCOR Reset' box and then clicking on the 'Refresh' tab. Note that the 'Faults' display shows two types
of faults, Latched and Immediate. The only way to clear a 'Latched' fault is with the software 'MCOR
Reset' selection. An 'Immediate' fault can be cleared by using the EMCOR front panel Reset button.
The 'Faults' display should now appear as shown in screen shot , with all MCOR faults appearing in
green as shown on the panel, and no flashing red LEDs as shown on the MCOR module(s). It should be
noted at this time that even though the 'Faults' panel displays 'Magnet' and 'External Interlock' faults,
they are not active on the EMCOR module at this time (have not been implemented) and will not
display faults. Once the fault(s) of the MCOR modules has been cleared, the EMCOR module and
MCOR modules are ready to be programmed per the instructions below.
The application is ideally suited for configuring the current setting on any MCOR module and then
determining if the output setting matches the desired setting. The following instructions can be used as
an example to set an MCOR module's current setting and then reading the value back to confirm that
the setting was properly performed. The screen shots below will aid in the use of the application.
From the main panel of the application click on the 'DAC' button.

Select the channel to be set from the 'Channel' pull-down (Screen shot 4) at the top left of the DAC
panel. Next, set the 'DAC Full Scale Current' setting from the 'Full Scale Current' table below. This
setting will be based on the type of MCOR module being used (for an MCOR 12 module as an
example, '12. 0768' would need to be entered in the 'DAC Full Scale Current' window). Once this
value has been set, you must then hit the 'Enter' key. Use the same table to determine the Monitor ADC
and Feedback ADC settings and enter those values using the 'Enter' button as well. Once those values
have all been entered, click the 'Configured' box at the bottom of the panel. Then set the 'Set Point' to
the desired value of current and hit the enter or return key (note that there must be a load connected to
the output on the back of the crate before any current will flow). The 'Set Point' window cannot be set
to a value unless the 'Configured' box has been checked. Click on the 'Refresh' button for the changes
to take effect on the panel display. Select the 'ADC' panel (from the main panel). This panel (screen
shot 5) will enable the user to monitor any settings made and determine that the output is the same as
what was requested (after clicking the 'Refresh' button). The 'DAC' panel also displays the Feedback
and Monitor current values for the channel selected.
Note that a ramp rate for the current to reach full level can be set by entering the desired value in the
'Ramp Rate' window (DAC Panel). The 'Ramp Mode' box must be displayed for the setting to take
effect after the enter button is pressed. The value entered in the ramp rate window is in amps/second.
The alternative to 'Ramp Mode' is the 'Immediate' Mode.

The 'Bulk Supply' Panel is shown in screen shot 8 below. This panel is used for enabling/disabling an
external bulk supply only. The bulk supply must support being remotely enabled/disabled, which is
accomplished by the crate via the 'Crate OK' connection on the back of the crate. This connection is a
BNC connector (J2) which is a dry contact (relay) output. When enabled ('PS On/Off' box checked) a
short is placed across the enable connection of the power supply pins to turn the output of the bulk
supply on. The user must consult the manual of the specific power supply in use to determine the
connections necessary for this function. BiRa Systems can help with this if necessary.
It is necessary to configure the bulk supply properly to ensure that the supply comes up in the correct
state so that the output of the supply does not come on until commanded. The bulk supply voltage,
Over Current, Over Voltage protection must be set up locally and cannot be controlled by the EMCOR
module. The power supply should be set up so that when powered on the output is enabled but the
output is not on. Note that it is not necessary to remotely access the bulk supply output. The bulk
supply may be used manually by the user if desired.

The USB application can also be used for monitoring the Xilinx (FPGA) temperature and voltage.
From the main panel select 'XMON' and the panel shown in screen shot 8 will appear. The current
values of the 1.0V and 2.5V supply voltages and the temperature of the part will be shown upon
clicking the 'Refresh' button.

The front panel of the EMCOR module is shown below. The J9 connector is used for USB
communication. The P9 connector (JTAG) is used for programming of the FPGA, which is done by
BiRa Systems and should never need to be accessed by the user. The jumper that can be seen in the P9
connector is for stability of the boot-up process and should not be removed. The EVR connector is not
active at this time. The EPICS CA (J5) connector is for Ethernet communication. The COM (J7)
connection port is used for serial communication. CPU RST (S2) is a switch that when activated will
reset the CPU, which will cause a re-boot of the module to occur. The Fast Feedback function is not
active at this time.

Remote PCI Register Information
The tables below contain detailed information on the EMCOR Registers. Refer to the following tables
for use in accessing data from the EMCOR module.
Some of the registers may not be active since some of the features of the EMCOR module have not yet
been incorporated.
The registers may be accessed by a GUI that resides on the PC that contain the CPU boot-up software,
and is a LINUX based OS.
Should it be necessary or desirable to access the PCI Registers, the following instructions should be
used. The following instructions assume that the CPU boot-up process has completed normally (see
boot-up instructions below).
Open up a terminal on the LINUX based machine used for the boot up process, and enter the following,
being careful to make the entries exactly as shown.
"cd emcor-python-package/Python-RemotePCI-GUI". Once this information is entered you are in
the correct directory to access the function. Next, enter "python pyrpci_gui.py", which is the actual
python based GUI. In order to access a desired register it is first necessary to enter the IP address
(172.16.0.100) at the top of the GUI, and then hit the connect button. A screen shot of the register is
shown here.
18

Once the GUI has been accessed, the specific address of the register with the desired data must be
entered, and a read of the register executed. The data is in a 2 bit hex format which must then be
converted to a decimal equivalent. Information in the tables below will indicate what format the data
is in (generally signed or unsigned integer) and the units of the data.
As an example of how to convert the data to usable information, suppose that one wanted to know what
the Set point requested value was for channel 7. The BAR (Base Address Register) tells us that the
Channel Control Registers reside between address 0x00000000 to 0x00000 C0. The EMCOR channel
registers table tells us that the base address for channel 7 is 0x000001c0. Since the channel settings
registers table shows us that the information we're looking for (Set Point Requested) has an offset of
0x00, we would enter the address 0x000001c0 into the GUI and request a read of the information in
this register. In this case the data in the register reads 0x000f4240. The channel settings register tells us
this data is a signed integer format with units of uA. When translated to decimal, the result is 1000000,
or the equivalent of 1amp, which is the current set point for channel 7.
The BAR 0 (Base Address Register) Memory Map of the EMCOR Registers is shown below.
