1 . I nt r oduct ion
Em bin’s ETM 1 3 1 is a Serial t o Et hernet Convert er m odule wit h 8051. ETM 1 3 1 can
be used ext ensively t o read t he dat a over t he serial port and send t he dat a via
Et hernet
in
t he
packet s
form at .
At
t he
heart
of
t he
board
is
Phillips
P89C51RD2/ P89C668; t his provides advance feat ures like I SP. The m icro cont roller
has 64KB flash m em ory and 1KB/ 8KB on- chip RAM. The Module board com es wit h
RS- 232 int erface t o allow user t o program t he m icro cont roller direct ly from PC.
ETM 1 3 1 board reads t he dat a from any Serial Port and sends t o t he Et hernet ( LAN) .
ETM 1 3 1 is a unique hardware and soft ware com binat ion providing t he serial dat a
send t hrough t he Et hernet . Hardware reference and soft ware applicat ion program s
also sim plify 8051 based hardware and soft ware developm ent . This board is also
having t he facilit y of Soft ware flow cont rol or Hardware flow cont rol and No flow
cont rol, you can select t he Soft ware flow cont rol or Hardware flow cont rol or no flow
cont rol opt ion t hrough t he CONFI G m enu. SERI AL BUFFSI ZE is 100byt es, so wit hout
S/ W or H/ W flow cont rol we can t ransfer t he 100byt es at a t im e wit h out dat a loss.
The t im e gape bet ween t wo t ransm issions should be approxim at ely 5m sec. TCP

Et he r ne t ca r d conne ct ivit y: To connect t he Microcont roller t o t ransfer t he
dat a from Microcont roller t o t he Et hernet RTL8019AS is used in ETM 1 3 1 . Et hernet
connect ivit y is t he m ain feat ure of ETM 1 3 1 . So t hat one can use it according t o t he
need. RTL8019AS is connect ed t o t he Microcont roller t hrough t he port 0 and port 2.
I n ETM131 RTL8019 we have used in 8bit m ode in int errupt m ode. The fallowing are
t he feat ures of t he RTL8019 if user want s t o im plem ent his own developm ent he can
im plem ent on t his feat ures.
The RTL8019AS is a highly int egrat ed Et hernet Cont roller. Wit h t he t hree level
powers down cont rol feat ures, t he RTL8019AS is m ade t o be an ideal choice of t he
net work device for a GREEN PC syst em . The full- duplex funct ion enables
sim ult aneously t ransm ission and recept ion on t he t wist ed- pair link t o a full- duplex
Et hernet swit ching hub. This feat ure not only increases t he channel bandwidt h from
10 t o 20 Mbps but also avoids t he perform ance- degrading problem due t o t he
channel cont ent ion charact erist ics of t he Et hernet CSMA/ CD prot ocol. The Microsoft ’s
Plug and Play funct ion can relieve t he users from pains of t aking care t he adapt er’s
resource configurat ions such as I RQ, I / O, and m em ory address, et c. However, for
special applicat ions not t o be used as a Plug and Play com pat ible device, t he
RTL8019AS also support s t he j um per and propriet ary j um per less opt ions. To offer a
fully plug and play solut ion, t he RTL8019AS provides t he aut o- det ect capabilit y
bet ween t he int egrat ed 10BaseT t ransceiver, BNC and AUI int erface. Besides, t he
10BaseT t ransceiver can aut om at ically correct t he polarit y error on it s receiving pair.
Furt herm ore, 8 I RQ lines and 16 I / O base address opt ions are provided for grand
resource configurat ion flexibilit y. The RTL8019AS support s 16k, 32k & 64k byt e
