• Install FPROM in ROM socket of TCP/IP and set IPL switch of
TCP/IP to "program rewriting mode".
• Power on the ER-A771, 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 digits
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~)

5) Data Transmission Check
Data transmission is checked in the system already established. The
system is composed of one master machine and a max. 63 satellite
system is composed of one master machine and a max. 63 satellite
machines.
Note when starting the check:
• When checking the set in which the LAN setting has been completed,
disable the LAN setting before starting this check.
• When testing the system already established, disconnect the LAN
cable of the sets not subject to test, or disable the LAN setting. Leav-
ing LAN enabled may cause data to be destroyed.
• The transmission test setting must be performed after disabling the
LAN setting of all the sets in the system. For the transmission check
setting, first, set the satellite machines, then set the master machine.
ER-A771 DIAG uses private IP address. This DIAG assigns Private IP
addresses to 64 terminal numbers to simplify the test as shown below.
When performing data transmission check, be sure to physically discon-
nect other network where these IP addresses are set.
