Hints

The maximum number of units in serial connection is 14 LA-01:s.
The drop channel (no 1) is configured as DCE (Data Communication Equipment).
Most printers, PC’s and terminals are set as DTE (Data Terminal Equipment).
Some recommendation of cable configurations are given below.
If any problems do occur on set up of the LA-01:s, the LED’s will be helpful.
