DCE LA-01 channel 1

Hints

LA-01 has three channels and they can be configured as RS-232/V.24 or as W1
connection. The LA-01 splits the line and repeats the signal in a multidrop system.
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.

• PWR: The unit has power.

• RD channel 1: Data received from channel 2 or 3

• TD channel 1: Data received from connected unit

• DCD channel 1: Indicates that W1 is connected to channel 1

• DCD channel 2: Indicates that W1 is connected to channel 2

• DCD channel 3: Indicates that W1 is connected to channel 3.
