System watchdog and voltage supervision There are two voltage supervision chips that control the system reset signals. The +3.3V supervision chip outputs reset signals for +3.3V devices. Reset is activated when voltage is below 3.08V. It also has a watchdog that is refreshed in normal operation and in standby. The +5V supervision chip outputs reset signals for +5V devices. Reset is activated when voltage is below 4.63V. +5V reset causes also +3.3V reset through a FET.
2.1.4
DC/DC board The DC/DC board converts the output voltage of AC/DC unit, external DC unit or battery voltage to various supply voltages for the electronics of FM monitor. The DC/DC board takes care of the battery charging.
Figure 4
DC/DC Board
DC/DC board functional blocks DC/DC board operation is controlled by the PMC (Power Management Controller) CPU. PMC takes care of power path controlling and power supplies' sequencing. It communicates with the main CPU via serial communication. PMC also measures DC/DC board voltages and currents. High efficiency switching power supplies and power path switches are used on the DC/DC board. This is because of no-fan requirement for PM monitor as well as maximizing the battery time. Circuit breakers make VSYS and MOD voltages short-circuit protected. Also the battery charger, +5V and +3.3V switchers withstand short-circuit. +5V_OUT is disconnected from +5V by a circuit breaker in case of +5V_OUT overload. The boost converter can be set to two different output levels. The higher one is used to give the battery charger adequate input voltage when the DC/DC board input comes from external DC source. The lower one is set in ACDC use to keep the boost converter enabled but passed by a diode and thus not 7 Document No. M1018511-3
Datex-Ohmeda S/5™ FM
switching, which minimizes the power loss. When the ACDC voltage drops the boost converter starts regulating its output and keeps the MOD voltages at a level a little lower than the one in ACDC use. In battery use the lower output voltage yields a little better efficiency, too. Smart batteries, battery charger and PMC communicate via SMBus (System Management Bus). It is a two-wire interface closely resembling I2C. Smart battery controls the charging and calculates and stores the capacity information as well as other battery related data. Batteries can be charged when external DC or ACDC voltage is present. Block diagram of the power supplies is represented in Figure 5

Battery charger Battery charger is a Level 2 Smart Battery Charger. It communicates with the batteries and PMC CPU via SMBus interface. The charger acts as a SMBus slave device that responds to charging current and charging voltage values sent to it by a Smart Battery. The charger includes input current limiting feature. In a case where the input current exceeds the limit the charger reduces the output current to keep the input within the limit. The currents of the MOD voltages (VMOD, I/O_VMOD) are taken through this current measurement as well. This results that the charger reduces its output current if the sum of the charger input current and MOD currents exceeds the input limit. The purpose of this is to prevent the input power sources from getting overloaded if MOD power is increased during charging.
Power path switching electronics The power source to be used (batteries, external DC or AC/DC output) is chosen initially by a ‘power path controller’ inside this block. The PMC CPU has full control over the power path management after the initial choice is made at startup.

AD/DC unit The AC/DC unit is a compact power supply based on new high-efficiency technology from Condor. It is designed for 65 watt continuous output with convection cooling, 15.9V requirements, and universal AC input. This AC/DC unit is especially well-suited to medical systems. The high-efficiency allows it to function in an enclosed case, with minimal heat dissipation.

2.1.10 Wireless LAN option, F-FMW S/5 Wireless Network is an extension to, or an alternative for, a wired Datex-Ohmeda Monitor network. It provides same network services than the wired S/5 Network. The monitor network is a local area network based on standard Ethernet technology. The monitor network is formed by connecting one Central and up to 32 bedside monitors together.
11 Document No. M1018511-3
Datex-Ohmeda S/5™ FM
The Central and the bedside monitors are connected to a 10 Mbps hub. The hub works as a multiport repeater and controls the information flow between all the devices connected to the monitor network. The communication protocol for the monitor network is Datex-Ohmeda specific. Wireless bedside monitors can use both the wired and wireless network. If the network cable is connected, the wired S/5 Network is used. Network connection is changed automatically between LAN and WLAN. LAN overrides when available. For using Wireless LAN connection, the monitor frame with ready-fitted WLAN option F-FMW is required. For configured parameters please refer to the S/5 Network, Wireless LAN Installation Guide.
2.1.11 Batteries The S/5 FM has two lithium-ion batteries, located in the battery compartment. The DC/DC board connects one of the batteries to be the power source, if no power is received from the AC/DC unit or from an external DC unit. The battery charging is controlled by the DC/DC board. The batteries can be charged separately, and screen symbols and monitor frame LED indicators indicate their charging level and possible failure. NOTE: When the monitor is battery powered, the green battery LED is on. When the monitor is mains/ external DC powered, the green mains/external DC LED is on.

When activated, the signal is set to the high state and remains at the high state until the alarm situation is over or the SILENCE ALARM key is pressed. The high state range is from 2.8 to 5 V, while the low state range is from 0 to 0.8 V. If the output signals are used simultaneously with the coding element, the B-UPINET Y-cable, order number 889308, should be used.

Digital and analog outputs
Digital outputs There are separate digital outputs. Both signals use TTL-level. The outputs are: Defibrillation Sync. and Nurse Call. The Defibrillation Synchronization Signal is obtained from Synchronization connector X5, pin 1. The Nurse call is obtained from Net ID connector X9, pin 8. Defibrillation Sync indication is generated by ECG. When active, the signal is state 1. After 10 ms the signal is reset to state 0. New Defibrillation Sync is not generated before the indication is deactivated. The delay from the R wave peak to the start of the signal is maximally 35 ms. Nurse Call indication is generated by red, yellow and white alarms. When activated, it is set to state 1 and remains at that state until the alarm situation is over or SILENCE ALARM key is pressed. The range of state 0 is from 0 to 0.8 V, and range of the state 1 is 2.8 to 5 V.
Analog outputs S/5 FM produces two analog real-time signals. The Direct ECG signal is available in Defib&IABP sync connector X5 pin 8 and Net ID connector X8, pin 3. The other signal is Invasive pressure output. It is available in Synchronization connector X5 pin 7. NOTE: When source of the selected analog output becomes invalid (for example, transducer is disconnected), the last valid waveform information remains on the output and the numerical information is no longer valid. Direct ECG Delay (max.): 15 ms Gain ECG (out)/ECG (in): 1 V/1 mV Pacer: 5 V and 2 ms pulse
