Menu: Comport / Settings
The ‘comport / settings’ webpage defines the parameters for the ENC's integrated comport/serial port.
ENC-200™ encoders are always comport servers and DEC-200 decoders are always comport clients.

Settings:
Description:
Mode:
Specifies the comport mode.
‘Console’
enables access and control of the ENC-200™
configuration via the com-cable (null modem cable). Use this
cable to set the ENC-200™ configuration when you do not want
to use web access.
‘Passthrough’
enables setting the comport to a serial mode. RS-
232 devices can be connected and controlled via the comport.
This is useful, for example when cameras or other non-IP, non-
network devices need to be remotely controlled. RS-232
commands can be tunnelled and sent via TCP/IP to the comport
server, where they will be returned into native RS-232
commands. When a connection is opened from the client (e.g.
decoder) to the IP-address of the encoder at port 7777, the serial
function in the ENC-200™ is activated and any data (string) is
passed straight to the connected RS-232 device. Once the
connection is established, this also works the other way for
information coming back from the RS-232 device.
‘Packet’
enables the packet mode. The ‘Packet’ mode enables
the tunnelled transmission of data with the compliance of the
temporal sequence. This mode is incompatible to other COM
Servers or Clients. That means the ‘Packet’ mode can only be
used between ENC-200™ encoders and DEC-200™ decoders.
At the ‘Packet’ mode the transmission is transparent and only the
parameters of the bitrate and the databits are set fix to 19200
bit/s, 8 databits. Data, which are sent as a block, shall be
outputted as a data block without gaps on the receiver side. Data
blocks, which are split with a gap, shall not be summarised on the
receiver side. Data blocks are sequenced signs with gaps which
are smaller than 4 Bytes.
Bitrate:
Specifies the used bitrate in bits per second.
Databits:
Specifies the databits. You can choose between ‘7’ and ‘8’.
Parity:
Specifies the parity. You can choose between ‘none’, ‘odd’ and
