12.2 Remote Control Connection Options This section gives the available options for connecting DN9848E and DN9848 units, and also HELIX
DN9340, DN9340E, DN9344 and DN9344E units, to enable remote control via a laptop or PC.
All units in a system must be running the same protocol version. The protocol version is determined by
the first digit in the software version, for example, if a DN9848E unit was running host software version
4.00, the protocol version is 4.
Note
Although there are many combinations available for remote operation, it is always worthwhile
remembering that Ethernet provides faster operation than serial.
12.2.1 Single-unit serial connections
Note
The following converters are the only converters supported by Klark Teknik. Even
though other converters may seem to work, we cannot guarantee their correct
functionality and compatibility when used with our products.
To connect a single unit via serial RS-232
The KT RS-232 host cable (supplied with every unit) is connected to the front panel of the unit and then
to the RS-232 port on the laptop/PC.
To connect a single unit – USB to front panel
The KT RS-232 host cable (supplied with every unit) is connected to the front panel of the unit and then
to a KK Systems USB232 USB-to-serial converter. The converter is then connected to a USB port on the
laptop/PC via a USB cable.
To connect a single non-Ethernet unit – USB to rear panel
A serial RS-485 cable is connected to the rear panel of a DN9848, DN9340 or DN9344 unit and then to a
B+B Systems USOTL4 USB-to-RS-485 converter, using a serial RS-485 cable. The converter is then
connected to a USB port on the laptop/PC via a USB cable.
