= Front panel connectors =

From top to bottom:

* SFP connector - 1GigE fiber/copper/DAC
* 4 LEDs
* eSATA - clock+trigger input
* FMC daughter card slot
* 2 LEMO
* 16 MCX analog inputs

= Onboard switches and connectors =

* FP_SW1
* FP_SW2
* SEL1 rotary switch 0..F - MOD-SEL20..23
* SEL2 rotary switch 0..F - MOD-SEL16..19
* JTAG FPGA
* JTAG MAXV
* "reset" button
* SD card slot
* "Display" connector
* 16x 3 position switches for gain and input (front/back) selection

= LEMO connectors =

<pre>
|
|
|LEMO1A|LEMO1B|
|
|
</pre>

LEMO connectors are controlled by two position switches FP_SW1 (LEMO1A) and FP_SW2 (LEMO1B):

<pre>
|
|      ---XX-
| left |..XX| right
|      ---XX-
|
</pre>

* right switch position (next to mark): DAC output
* left switch position (opposite from mark): NIM input

= Onboard LEDs =

<pre>
|
|
|0|1|2|3|
|
|
</pre>

* FP_LED0 - "clock_synched" (from qsys)
* FP_LED1 - "led_trigger_input" (same as "trigger_input_adc")
* FP_LED2 - "run active" (same as "force_run")
* FP_LED3 - "led_link" (from qsys)

= Onboard thermometers =

* Temperature readout chip: LTC2983CLX#PBF
* Thermometers: 9x RTD1..RTD9 type PT100. The first 8 are on the back of the PCB next to the analog amps, the last one is on the front next to the FPGA.
<pre>
RTD1 sensor_temp[0] opamp 1-3
RTD2 [1] amp 2-4
RTD3 [2] 5-7
RTD4 [3] 6-8
RTD5 [4] 9-11
RTD6 [5] 10-12
RTD7 [6] 13-15
RTD8 [7] 14-16
RTD9 [8] between the FPGA and U11-U15
</pre>

= Analog gain and input selector switches =

The switches labeled SW1..SW16 (right side) are the input selector switches: default position (up; next to the dot) is "rear vme connector", reverse position (down) is "front panel MCX connector".

The switches without onboard label (left side; label on the schematics is "SW1") are the gain selection switches: default position (down; next to the dot) is "gain x4", reverse position (up) is "gain x1".

= Onboard hardware =

* 2-output DAC: Maxim MAX5877EGK+D, output driver TI OPA 2690IDG4, range +/- 1V open, +/- 0.5V into 50 Ohm
* I2C MAC chip: Microchip tech 24AA02E48T-I/OT, I2C addr 0xA0, MAC_SCL, MAC_SDA
* FPGA Boot flash: Micron Serial NOR flash memory: N25Q00AA13GSF40G

= Board schematics =

[[:File:GRIF-ADC16_Rev1.pdf]]

= ALPHA-g board configuration =

* rotary switches SEL1, SEL2 - set to zero
* FP_SW1, FP_SW2 - adc01..08: FP_SW1 left (NIM input), FP_SW2 set right (DAC output); adc09..adc16: both left (NIM input)
* analog input switches: default position (next to mark): from left to right: down, up, down, up, etc
* FMC connector: FMC-ADC32 module
* FMC connector: FMC-MiniSAS module cable plugs into the bottom connector
