Step 5: Connect Power Supply
➤
For AC power, use the power supply that comes with the BSIA system. It has a universal input
(110/220VAC), operates at 50~60 Hz, and provides -48VDC.
Note
The power supply includes a cable with a
barrel-jack connection (see
Figure 20 ) to
the BSIA and 110VAC cable.
CAUTION!
Connect to power, but do not
power on until the entire system
is cabled.
➤
To connect to power when -48VDC is required
1. For DC power, a power cord with the
following is required:
♦ 18 AWG wire
♦ 2.1mm ID x 5.5mm barrel jack (Switchcraft, Inc. S765 or equivalent) with minus (–)
potential center lead and positive (+) shield lead
2. Connect the barrel jack to the BSIA at J1 (see Figure 20 ).
Note
Battery source requirements are -44VDC to -56VDC @2 amps. An inline, slow-blow fuse
rated 3 amps @250VAC must be installed as close as possible to the battery source on the
minus potential side.
3. To prevent accidental removal of the power cord connected to J1 on the BSIA, tie wrap the
power cord to the power strain relief above the ground screw on the BSIA (see Figure 22 ).
Step 6: Connect PC
1. Insert one end of the RS-232-C
cable with a DB9 or DB25 adapter
into the serial port in the back of the
PC (see
Figure 21 ).
2. Insert the RJ-45 connector into the
back of the BSIA (J2) (see Figure
22 )
