Physio Module
The optional Physio module (see “Physio Module Option” on page43) installs in one of the PC
drive bays. The front panel of the module bears two input connectors:
•A 3-lead ECG physio connector
•An auxiliary analog input (standard ¼-inch phone jack)
An externally generated auxiliary analog input signal using the phone jack can substitute for the
3-lead ECG physio connector at the front panel. You can also input an auxiliary ECG waveform
from an external patient monitor and display it, in all modes. The R-wave from this signal can
serve as a time reference for the system.
Power Sup ply
The power supply is an enclosed, self-contained, replaceable module that mounts under the
e-box at the right side of the cart. It accepts AC input sources from 100V to 240 V, at 50Hz or
60 Hz.
The power supply provides all required AC and DC voltages to the system. Three switched
120 VAC outlets for powering the monitor and two peripheral devices are at the rear of the
power supply. An unswitched outlet powers the M2540A’s internal PC. When the system is shut
down, only the 120 VAC outlet to the PC is enabled. A green LED on the left front of the power
supply lights when the power supply is energized.
Optional
Peripherals
(VCR,
Printers, and
Image
Devices)
The M2540A supports several types of optional peripheral devices:
���VCRs, including NTSC-format and PAL-format models
•Thermal color and thermal black-and-white printers
•Various biopsy kits (See “Supplies and Accessories” on page202.)
•A magneto-optical disk (MOD) drive for data storage
“Optional Peripherals” on page 201 lists all peripherals supported by the ultrasound system.
Some peripherals mount on a shelf below the system control panel.
