EtherPath-X4 User’s Guide
Flow Control
The choices are “None”, “XON/XOFF”, and “RTS/CTS”. It is common to use NONE for installation
troubleshooting, then set it correctly to match the connected device. If RTS/CTS is used, the cables must
have handshake lines wired correctly. RTS Toggle is a handshake mode commonly used with half duplex
modems. The RTS output is asserted when the unit has data to transmit and it will remain asserted for
approximately 5ms after the last character has been transmitted. The CTS signal controls output flow.
Baud Rate
Speeds between 300 bps and 230.4Kbps are supported.
Parity
The choices are “None”, “Odd”, or “Even”.
Data Bits
The choices are 7 or 8. This does NOT include the parity bit. The two most common settings are 7 bit
PLUS appropriate parity or 8 bit with NO parity. Default is 8 bits.
Stop Bits
The choices are 1 or 2. Commonly use 1.
DCD Input Control
If Forced On, the EtherPath responds as if interface DCD Input is always high. If From Interface, its
condition is a read from the RS-232 cabling must be correct for proper operation.
Client Dial Mode
Set port dialing mode [AT Dial Hardware, (DCD) Dial, or Nailed Up] In AT dial mode, modem-like AT
commands are used to connect to a remote server. In DCD dial, the client automatically
connects to the remote server when the DCD signal goes high. In nailed-up mode, the DCD
signal is ignored, and as soon as the client is activated, it connects to the remote server.
Mode
Server mode allows this serial port to be accessed via a raw TCP socket on this port. Client mode connects
the serial port to a remote server. Telnet-server works like server mode, but the connection uses telnet
standard character escaping and can also support changing baud rate, stop bits, and start bits using the
RFC2217 protocol. Client-telnet allows the serial port to connect to a server which is using telnet mode..
Client's Remote IP Address
In server mode, this is the address (e.g. 192.168.1.4) of the client serial device server. In client mode, it is
the address (e.g. 192.168.1.5) of the remote server.
Server Ethernet Port
In client mode, this is the number of the remote server port to connect to. In server mode, this establishes
the server socket port that accepts connections for this serial port.
