[1] These pins have multiple internal signals that they can be connected to. The
connection options are selected with internal jumper plugs (see Appendix F -
Internal Jumper Block).
Notes
[2] This pin is normally setup as the serial port Data Terminal Ready (DTR) line,
which is an input for DCEs (input to the TS4000). As an alternative, this pin
can be setup to feed DC power into the TS4000.
Caution: The use of the DTR pin for a DC power input connection is
non-standard. Therefore the TS4000 serial port must not be connected
to a standard serial device that drives the DTR pin (i.e. a PC).
This could
result in the power supply voltage of the TS4000 being shorted to the DTR
output of the host serial port, which could damage to the host device.
Therefore, when connecting the TS4000 to a PC for configuration, make sure
that the cable does not have a DTR (pin 4) connection.
[3] This pin is normally setup as the serial port Data Set Ready (DSR) line,
which is an output for DCEs (output of the TS4000). As an alternative, this
