This service menu shows information about external communication. 
 
To enter this service menu from the 
Service View menu: 
1. Select Monitor. 
2. Select Communication.  
Network (with N-XNET or N-XDNET option) Shows information about communication with the 
Datex-Ohmeda Network. 
• Statistics In shows the number of received data packets and data bytes. 
• Statistics Out shows the number of transmitted data packets and data bytes. 
• Data errors shows the number of received erroneous data packets. 
Computer If. Shows information about communication through the I/O board RS-232 serial 
connector (X2).  
Interface status shows whether the interface through the connector is opened, 
active, or closed. 
• Opened indicates that the hardware and software for the interface is running 
but there is no connection, or that there have been errors in using the interface.  
• Active indicates that the interface is operating normally.

8.3.4 Watchdog Tests menu 
 
To enter this service menu from the Service View menu: 
1. Select Monitor. 
2. Select Watchdog Tests.  
Watchdog This test ensures that the watchdog functions properly. This test shows running 
seconds with an accuracy of 0.1 seconds. 
 When the safety element is working properly, the monitor restarts 1.5 seconds after 
the start of the test.  
In case of a malfunction, >20 s is displayed and the test will interrupt. In this case, 
the fault is in the safety element on the CPU board. 
WD by Overload This test ensures the functionality of a feature in which the software controls the 
monitor and detects an overload situation in the main CPU. 
When the feature is working properly, the monitor will restart 15 seconds after the 
start of the test. 
WD by UPI Not used in Cardiocap/5. 
WD by GSP Not used in Cardiocap/5.

Lower Led Checks lower alarm indicator LED (yellow). 
Dummy Press Tests the function keys. See the description for Direct action keys below. 
Keyboard Type Not used in Cardiocap/5. 
Service Data screen 
Service Data counts whenever a function is selected. 
• LEDs upper and LEDs lower—indicate state of Silence Alarms LEDs. 
• Direct action keys—items change their color when the corresponding function key is pressed. If 
the color does not change, the key may be mechanically damaged. Only the following checks are 
used in Cardiocap/5: Silence Alarms, Trends, ECG, NIBP, and Normal Screen. 
• Control wheel—Press counts when the ComWheel is pushed. Clockwise and Counterclockwise 
count when the ComWheel is turned. 
NOTE: Counters in this page are automatically zeroed when you return to the previous menu.

Timeouts—how many times the measurement unit did not respond to an inquiry from the CPU. 
Bad checksums—how many times communication from the measurement unit to the CPU broke 
down. 
Bad c-s by mod—how many communication errors the measurement unit detected.

Counting starts at power on and is reset to zero at power off. Nonzero values do not indicate a 
failure, but continuous counting (more than 50 per second) indicates a serial communication 
failure. Also, other measurement units can cause these numbers to rise.
