Connecting the Control Port
If you are using the control terminal, connect a cable prepared in
accordance with Appendix B between the control port connector,
designated CONTROL DCE (see Figure 3-1 in Chapter 3), and the control
terminal. If the control terminal is connected via modems, use a cross-over
cable.
Note The various interface cables should be shielded, in order to comply with FCC
rules. HCD-E1 and its data interfaces will work well even if the cables are not
shielded, but some radio interference may occur.
Connecting the
Power To connect the power to HCD-E1, refer to the appropriate section below,
depending on your version of the unit (AC or DC).
Warning
Before switching on this instrument and connecting any other cable, the
protective earth terminals of this instrument must be connected to the
protective ground conductor of the mains power cord. If you are using
an extension cord (power cable) make sure it is grounded as well.
Any interruption of the protective (grounding) conductor (inside or
outside the instrument) or disconnecting the protective earth terminal
can make this instrument dangerous. Intentional interruption is
prohibited.
For AC version, make sure that only fuses of the required rating, as
marked on the rear panel, are used for replacement. Do not use
repaired fuses or short-circuit the fuse holder. Always disconnect the
mains cable before removing or replacing the fuse. Whenever it is likely
that the fuse protection has been damaged, make the unit inoperative
and secure it against unintended operation.
AC Power Connection
AC power should be supplied to the HCD-E1 through the 5 ft (1.5m)
standard power cable terminated by a standard 3-prong plug
(see Figure 2-5). The cable is provided with the unit.
1. Check that the ON/OFF switch on the HCD-E1 rear panel is set to OFF.
2. First, connect the power cable to the connector on the HCD-E1 rear
panel, and then to the mains outlet.
DC Power Connection
To connect DC power to HCD-E1, refer to DC Power Supply Connection
Supplement.
