EVALUATION BOARD USAGE OPTIONS
In its most basic form, by utilizing the pre-loaded firmware and
configuring the ADuCM4050 switches appropriately, two
EVAL-ADIN1110EBZ boards can be used in standalone mode
(Figure 8 & Figure 9) without any connection to external
software to establish links with a link partner, indicated to the
user via LEDs. In standalone mode, power the EVAL-
ADIN1110EBZ with a 5-30 V supply at the P1 or P2 connector
or alternatively via USB. In this mode, a UART terminal can
optionally be used for extra user feedback and interaction with
the ADIN1110 versus solely based on LED activity.

Figure 9. Two MAC-PHY boards, Exercise PHY functionality
Firmware is configured by DIP switches (see Table 5) and the
MAC-PHYs are set per the hardware pin configuration DIP
switches (see Table 3). In the example depicted in Figure 9, only
the PHY portion of the ADIN1110 is exercised, no MAC
function is exercised. The MAC-PHY on board 1 is set to
generate and check frames and MAC-PHY on board 2 is set in
PHY MAC Interface Remote Loopback mode. Status
information is reported via UART/USB and also indicated on
LEDs. An alternative, but equally valid set-up would be to use
an EVAL-ADIN1100FMCZ PHY evaluation board as the link
partner board (i.e. board #2 in Figure 9).
Figure 10 depicts an example whereby the MAC function is also
exercised. This does not require any extra hardware or software
versus the previous example in Figure 9. It is invoked by setting
the ADuCM4050 configuration switches to enable µC Frame
Generator/Checker and µC Remote Loopback modes
respectively. The optional JLINK connections are shown in
cases where it is required to modify the firmware for any
reason.
The ADuCM4050 on board 1 is set to generate and check
frames and either the PHY within the MAC-PHY on board 2 or
the ADuCM4050 on board 2 is set to loopback the frames to
board 1. Again, status is reported via UART/USB and also
indicated on LEDs.

A more advanced use of the EVAL-ADIN1110EBZ evaluation
board is in conjunction with a media converter board to
convert between 10BASE-T1L and 10BASE-T ethernet
protocols – this is depicted in Figure 11. In this example the
local application periodically reads the MAC-PHY status and is
linked to a web page. The TCP/IP stack can be managed via
UART using either fixed or dynamic IP address allocation. The
media converter board is then used to convert 10BASE-T1L to
10BASE-T ethernet, for which common web browsers can be
used to access the associated information.
