General Information 

The  ETC  II  Network  Communicator  is  a  multi-port  Internet-to-serial  that 
connects  multiple  serial  RS-485/422  or  wireless  ZigBee  devices  to  the 
Internet via a local Ethernet network or via public telephone lines. It can also 
be  used  as  an  Internet-to-Internet  router  for  connecting  master  stations  to 
remote slave devices that are directly connected to the Internet. The  ETC II 

provides transparent master-slave connections using TCP/IP versions of the 
popular  industrial  fieldbus  protocols  such  as  Modbus  RTU,  DNP3,  and 
SATEC ASCII.  

The embedded Data server allows the  ETC II to automatically acquire data 
from slave devices and to store it in the memory exchanges or in the data log 
files  in  non-volatile  memory,  so  a  user  application  can  read  blocks  of 
acquired  data  directly  from  the  ETC  II  exchanges  without  waiting  for  a 
response  from  slow  serial  and  wireless  devices.  The  application  can  also 
write data to slave devices via the ETC II exchanges instead of waiting until a 

remote  device  is  accessible.  The  Data  server  may  be  programmed  to 
monitor the slave device’s status registers for specific events and to record 
them to a log file, and send alerts to a remote server. 

Features: 

 

Ethernet 10/100Base-T port communicating to the IP network 

 

Service USB Device port to communicate with PAS 

 

Two RS-422/RS-485 master ports for connecting to serial networks 

 

Service RS-232 port that can be used as a slave port for serial master 

applications 

 

Optional CELLULAR modem port communicating to the IP network 

 

Connections using popular field-bus protocols such as Modbus TCP 

 

Terminal connection 

 

Telnet service 

 

Embedded Data server: up to 250 real-time data exchanges, up to 250 

data write exchanges, and up to 250 16-bit status event exchanges 

 

Up to 250 data log files 

 

Event log for recording status change events and device diagnostics 

 

Table top, DIN Rail or wall-mounting options 

 

4  Mbyte  non-volatile  memory  with  battery  backup  for  storing  data  and 

event files 

 

Real Time Clock 

 

120/240V AC/DC operation
