Serial Mode:
Set this mode according to the WAN connected equipment (DCE). Possible choices are:
• RS-530: this serial mode uses a DB25 connector.
• V.35: this serial mode is usually used through an M34 connector. A DB25F/M34M
adaptation cable could be necessary.
• V.24/V.28: this serial mode uses a DB25 connector.
• X.21/V.11: this serial mode is usually used through a DB15 connector. A DB25F/DB15M
adaptation cable could be necessary.
Changes in the serial mode are taken into account when this menu is exited and after answering Y
to the question :
"Some parameters changed: Do you want to restart connection? (Y/N)"
Bridge filter:
This parameter activates or disables the filtering of the Ethernet frames depending on their
destination address and the known local addresses.
• Disable: no filtering, all frames are transmitted
• Enable : filtering. Only frames whose destination address is unknown, are transmitted.
Compression:
This parameter activates or disables the data compression. It will be efficient up to 256Kbit/s.
When using SeriaLAN at higher rates data compression must be disabled.
• Disable: no data compression.
• Enable : all the traffic is compressed. To be used at rates less than 256 Kbit/s.
Link Available :
This parameter determines the criterion taken into account by SeriaLAN to consider WAN
connection established. The possible choices are "Always" (in this case SeriaLAN considers that the
DCE is always connected) or one of the signals of the serial interface selected (by default CD or I
for X.21/V.11 mode).
Behavior of the outgoing signals:
This parameter sets the behavior of the outgoing signals of the serial interface of SeriaLAN (C in
mode X.21/V.11 or RTS and DTR in the other modes): those can be permanent (ON or OFF) or
follow the state of an incoming signal (I in mode X.21/V.11 or CD, CTS, DSR in the other modes).
The action on the signals takes effect at the exit of the menu without starting again connection.
Parameters are saved in the non volatile memory when the ‘P’ (Preceding menu) key is
pressed. The connection may be restarted to take into account the change of parameters
Otherwise, they will be used at the next reset of the unit only.
