NETWORK SCAN
The Network Scan function scans ALL possible device addresses in the network. The
scan is started by approving Start? Y/N in the screen mode of the menu: select Y and
press T. If the device has not been used before, all devices detected are displayed after
the scan and the connected PE unit channels toggle on the screen at one second
intervals in the Autoscroll mode. The screen can be stopped with the and buttons,
and the results can be browsed with these buttons.
During bus scanning, resistance is measured from all channels of all PEC-01
units connected to the system. Therefore Network Scan / Network View is
permitted in medical locations only when there is no activity in the area to be
monitored.
If the device already has a previously approved configuration, the AutoScroll mode
displays the measured value of each parameter and the approved value from the earlier
configuration saved in the EEPROM memory.
The results are approved with the T button, after which a confirmation is requested:
CONFIRM ALL/NONE. When ALL is selected, the values are saved in the memory of the
IM-01.MED unit. Note that all parameters must be approved at the same time. In other
words, at this phase the number and addresses of the devices and, in particular, the
number of PE unit channels and resistance accuracy must be checked carefully.
If you don’t want to change/approve all values simultaneously, use the Network View
function. It should be used when a small change is made in the system, for example,
one remote unit or one PE channel is added or removed and remeasuring all PE
resistances is not desired.
The texts shown in the AutoScroll and screen modes, including their descriptions, are
presented below. The xxx/yyy parameter displayed on the screen always means the
MEASURED/SAVED value. In addition to the numerical values, the following
abbreviations are used:
 MIS: A missing unit or PE channel (a measurement loop is broken, in other
words, the resistance is higher than 500kΩ)
 OLD: The device was also included in the previous approved configuration.
 NEW: The device is new, and was not included in the previous approved
configuration.
 ERR: The device is defective but communicates, or the resistance of the PE
channel is 2.55Ω…500kΩ
 --: The resistance of the PE channel has not been measured yet
 INACTIVE: A PEC-01 unit channel that has not been connected (the resistance is
higher than 500kΩ)
If the system includes even one defective device, the Network Scan results should not be
approved until the fault has been fixed. Such faults include, for example:
 A defective remote unit
 A defective channel in the PE unit
