Pins 9-19 are unused, open.

Data Terminal Ready

Data Terminal Ready output; indicates that the terminal is on and

operational. This line is enabled, pulled up to +12 volts through a 4.7K ohm

resistor.

Notes

1. On the LCM100-1 module pin 8 is not carried at the connector through P3 because most

computers provide this signal. Pin 8 may be carried to the connector, if desired.

2. On the LM100-2 module, the carrier detect signal is available at the connector because the

interconnected equipment is receiving a signal. Pin 8 may be disconnected at P3, if desired.
