MAX9264 Evaluation Kit
Evaluates: MAX9263/MAX9264
2.1.4)
Diagnostic:
EXIT_CODE_JTAG_ABSENT
.
The USB cable seems not to be connect-
ed, or possibly the USB device driver
software not installed. Check setup using
a known good unit. Verify that the 6MHz
crystal is working. Visually inspect failed
board FT232 chipconnections.
2.1.5) Exit the firmware loader program.
2.1.6) Disconnect the USB cable from MAX9263
EV kit Board #1 TX_B1.
2.1.7) Replug the USB cable into MAX9263 EV
kit Board #1 TX_B1.
2.2) Configure Board #1 TX_B1 and UC_B (MAX9263
EV kit) as follows:
2.2.1) JU1 (CDS) = 2-3 to allow UC_B firmware
to access the MAX9263 registers.
2.2.2) JU10 = 1-2 to power UC_B microcon-
troller from repeater-provided 5V power.
2.2.3) JU125 = 1-2 so UC_B can sense the
VSYNC input.
3) Prepare the repeater board set MAX9264 EV kit
RX_R1 plus MAX9263 EV kit TX_R1.
3.1) Update Board #2 RX_R1 firmware:

3.1.2) The firmware update batch file instructs
you to
Plug USB cable into Maxim
Evaluation Kit to begin firmware
update...
and
Press any key to con-
tinue...
After plugging in the USB cable,
wait at least 5s to allow Windows to catch
up. Press the Enter key to begin the firm-
ware update. After approximately 1min,
verify that the batch file reports
Exit code
= 0 EXIT_CODE_SUCCESS
.
3.1.3)
Diagnostic:
Windows reports
USB over
current surge
. Check if the USB connec-
tor is the type that has a separate back
shield that can short across the USB
signal pins. Pry off this back shield cover
to clear the short.
3.1.4)
Diagnostic:
EXIT_CODE_JTAG_ABSENT
.
The USB cable seems not to be connected,
or possibly the USB device driver software
not installed. Check setup using a known
good unit. Verify that the 6MHz crystal is
working. Visually inspect failed board FT232
chip connections.
3.1.5) Exit the firmware loader program.
3.1.6) Disconnect the USB cable from MAX9264
EV kit Board #2 RX_R1.
3.1.7) Replug the USB cable into MAX9264 EV
kit Board #2 RX_R1.
3.2) Modify Board #2 RX_R1 and UC_R (MAX9264
EV kit) as follows:
3.2.1) Install pins at JU141, JU142, GND, VIN,
and IOVDD.
3.2.2) Make sure that RX_R1 JU143 and JU144
are open.
3.2.3) Connect a wire between RX_R1 JU143
bottom pin (U14 level-translated U12
RXD0) and TX_R1 JU141 top pin
(MAX9263 TX).
3.2.4) Connect a wire between RX_R1 JU144
bottom pin (U14 level-translated U12
TXD0) and TX_R1 JU142 top pin
(MAX9263 RX).
3.3) Modify Board #3 TX_R1 (MAX9263 EV kit) as
follows:
3.3.1) Install pins at JU141, JU142, GND, VIN,
and IOVDD.
3.4) Configure Board #2 RX_R1 and UC_R (MAX9264
EV kit) as follows:
3.4.1) JU8 (
ENABLE
) = 2-3 so that
ENABLE
is
low, driving the video outputs on header
H1.
3.4.2) JU23 = open to disconnect IOVDD from
the on-board 3.3V regulator U2.
3.4.3) JU1 (CDS) = 1-2 to allow UC_R firmware
to access the MAX9264 registers.
3.5) Connect Board #2 to Board #3 as follows:
3.5.1) Connect Board #2 GND to Board #3
GND.
3.5.2) Connect Board #2 VIN to Board #3 VIN.
3.5.3) Connect Board #2 IOVDD to Board #3
IOVDD (powered by TX_R1 board’s 1.8V
regulator U2).
3.5.4) Connect RX_R1 header H1, pin 62
(PCLK) to TX_R1 header H1, pin 62
(PCLK).
3.5.5) Connect RX_R1 header H1, pin 40
(VSYNC) to TX_R1 header H1, pin 40
(VSYNC).
3.5.6) Connect RX_R1 header H1, pins 2–58
(D[0:28]) to TX_R1 header H1, pins 2–58
(D[0:28]).
3.6) Configure Board #3 TX_R1 (MAX9263 EV kit) as
follows:
3.6.1) JU10 = open (board #3 TX_R1
microcon-
troller is not powered).
3.6.2) JU1 (CDS) = 2-3.
4) Connect the 5V power supply to Board #2 RX_R1 as
follows (the USB does not provide sufficient current
to power the EV kit demonstration):
4.1) Set the 5V power-supply output voltage to 5V.
4.2) Disable the power-supply output.
