The SPEC4 connects 3 Serial RS232/485 ports and one current loop port
via the Ethernet TCP/IP network with up to 4 remote computers or other
SPEC4's. With the SPEC4, everything with a serial port connects to the
local network.
Hardware:
50 x 110 x 180 mm.
Power supply: 8 (300mA) to 35 Volt (80mA) DC or 12 to 24 Volt AC.
Build with the Quicc processor boards.
3 individually configurable serial ports with RS232 or RS485/422 selection.
Handshakes lines in RS232 mode.
1 current loop serial port with 2 separate current sources (16 possible
connections).
10 base T Ethernet connector (internal switching allows a point to
point connection, without a hub, if necessary).
Operation:
The 4 channels are transparent and completely undepended so you can
connect up to 4 apparatus to one or more PC’s.
Any PC or an other SPEC4 can open a connection to a chosen serial
port.
The SPEC4 is addressable by IP-address or name (WINS). Both the SPEC4
and WINS servers respond to a name query.
Configuration:
For configuration you can choose between a menu driven user interface
or a coded string for programmed configuration.
Fixed or automatic IP-address configuration (DHCP) and name registration
(WINS).
Serial port and Ethernet settings are done via the serial port or
a Telnet control session (TCP-port 23).
The telnet control session can also display the status of the different
connections and dump the receive and transmit buffers.
Baud rate ranges from 50 to 115200 Bd (the current loop port is limited
to 4800 Bd)
