- Directly to a serial port on the computer
- Directly to a USB port on the computer (a serial to USB converter
is required)
- Via a landline modem
- Via a GSM modem (see Eltek documents TU1016 and TU1017)
- Via Ethernet using a Moxa Nport 5110 (see TU1029)
14.2.1 Direct connection details
For direct connection from a PC serial port to a 1000 Series Squirrel, the
cable LC68 is used. If a serial port is not available on your PC, an
RS232/USB adapter can be used in conjunction with the LC68. The
preferred adaptor is the NewLink USB Serial Convertor (type
NLUSB0039) which is available from Eltek. Note: Not all USB adaptors
are compatible! Ensure the device is installed correctly and make a note
of the COM port number for each USB slot on the computer as it will be
required by the Darca software.
