Write MAC Address and the firmware.
(operation procedure)
• Install FPROM in ROM socket of TCP/IP and set IPL switch of
TCP/IP to "program rewriting mode".
• Power on the UP-3301, then execute the MAC ADDR&FIRM
WRITE diag.
• Enter three sets of three digits decimal from numeric key of touch
panel, and touch the ENTER key.
• Write the MAC ADDRESS of total 6 byte, which is comprising
SHARP maker code (08, 00, 1F) and the three hexadecimal dig-
its converted from three numbers entered with keyboard, into
dual port RAM (800000H~)
• Turn the power off and remove the EPROM from the ROM
socket of the TCP/IP, then set the IPL switch to "normal MODE".
• Power on the main unit.
Input: DUAL PORT RAM (80000H~)
