DT-7000/DT-7001 transceiver.
3. Connect the DT-7000/DT-7001 power supply to the DT-7000/DT-7001
Power Connector and to the 120 VAC/60 Hz wall power.
Note: The Port numbers listed above are the default ports. If you change the pro-
gramming port parameter in the software, then you must also connect the
programming cable to the appropriate MSIO port based on the selection.

Programming Ambulatory Transceivers (DT-4500)
To program the DT-4500:
1. Access the OpenNet LAN screen (page 101).
2. Click the Program AT button to open the Ambulatory Transceiver Program-
ming screen (fig. 77).
Fig. 77. Ambulatory Transceiver Programming screen
3. If the “No response from transceiver” popup appears, check the program-
ming cable connections and the transceiver battery. To re-attempt, wait until
the I/O LED on the DT-4500 stops flashing, and then select the Read TX but-
ton.
4. Click the Tx Info button to open the Transceiver Information popup (fig. 78),
which displays the current information for the attached transceiver. Click OK
to close the popup
Fig. 78. Transceiver Information popup
5. Click the Read TX button to read the currently programmed information
located on the transceiver and update the fields on the Program Transceiver
screen.

6. Toggle ECG Filter (frequency response) to 0.5 or 0.05 MHz. This determines
how fast the ECG lead is adjusted after baseline changes.
WARNING: Program the DT-4500 transceiver to 0.05 Hz if you are performing ST analysis.
Otherwise, unpredictable and inaccurate analysis will result. You may use 0.5
Hz if you are not using ST analysis.
7. Click the Program Port button to select the MSIO port that will be used for
the transceiver programming interface. Clicking the button will cycle through
following options:
•MSIO 1
• MSIO 2 (DT-4500 default)
•MSIO 3
•MSIO 4
•None
Note: The Program Port field will only display the ports that are currently available
for the system. Thus, if all four ports are selected, and you decide to
change ports, none of the ports are available. You must select None on one
port in order to make it available (as the ports are mutually exclusive), and
then assign the available port to another device. Selecting None prevents
Port lockout.
8. Click the Device ID button to open a keypad that allows you to set the trans-
ceiver’s device identification number (0 - 1000).
9. Click the Network Key button to open a keypad that allows you to set the
transceiver’s network number (0 - 255).
WARNING: All transceivers must be programmed to the same Network Key as the Access
Points. This is an administrative procedure only. Do not attempt to program
the transceivers with the Network Key.
10. Click the LL Threshold button to open a keypad that allows you to set the
transceiver’s Loose Lead Threshold value (100-200). Electrode impedance
values below this threshold trigger a Lead Off alarm for all leads dependent
on the electrode violation. 150 is the default value.
11. Click the QL Threshold button to open a keypad that allows you to set the
transceiver’s Quality Lead Threshold value (100 - 200). This parameter
defines whether an electrode’s LED on the DT-4500 will illuminate when the
Attendant Present buttons are pressed. 156 is the default value.

Transceiver Impedance Values
The DT-4500 Ambulatory Transceivers electrode impedance values, which are
displayed on the OpenNet Transceiver Status screen (see fig. 86 on page 136), indicate
the quality of the signal connection and are not the actual impedance values that are
measured by the system. The electrode impedance values range from 100 to 200 (opti-
mal). The typical values range between 180 and 200.
If the electrode’s impedance value is greater than the defined Quality Threshold value,
then its LED is illuminated. The DT-4500 stores the Quality Threshold value and uses
this value to determine whether or not the electrode LED should be illuminated when
the Attendant Present buttons are pressed. See the PatientNet Operator’s Manual for
details on the DT-4500 Buttons and LED indicators.
Note: A Lead Off alarm will occur when an electrode’s impedance value drops to,
or below, the current Loose Lead Threshold value.
12. Click the PA SILENCE button to enable or disable the Procedure Alarm
Silence function for the transceiver. See the PatientNet Operator’s Manual for
details on the Procedure Alarm Silence function.
13. Click the Program TX button to program a transceiver with the new parame-
ters and read the programmed information back for validation. The trans-
ceiver is now programmed.
Note: The attached device (AT or IT) is only programmed with the new parameters
when the Program TX button is pressed. Simply changing a parameter’s
value does not program the device. Programming is a two-step process:
(1) modify the desired parameter(s); (2) press the Program TX button.
Note: An error message that reads “Programming failure” is displayed when the
parameters read back from the transceiver differ from the parameters that
were written to the transceiver.
14. Click the F/W Download button to display the Advanced Program Trans-
ceiver Firmware Download screen (see fig. 79 on page 126).
15. Click the Advanced RF button to display the Advanced Program Transceiver
RF Module screen (see fig. 80 on page 127).
16. Click the Exit button to close the Ambulatory Transceiver Programming
screen and return to the OpenNet LAN screen.

10. Click the OP Band button to set the operating band that will be used by the
RF Module.
• Typically, the 608.5-613.0 OP Band is selected. However, where the Patient-
Net System operates in the same hospital as another system (or systems) that
also use(s) the 608-614 MHz WMTS band, it will be necessary to select one
of the sub-bands. The sub-band should coordinate with the hospital’s spec-
trum policy.
• Additional sub-bands include: 608.5-609.7, 609.6-610.8, 610.7-611.9, and
611.8-613.0
WARNING: All transceivers must be programmed to the same OP Band as the Access
Points. This is an administrative procedure only. Do not attempt to program
the transceivers with the selected OP Band.
11. Click the Program TX button to program a transceiver and read the pro-
grammed information back for validation. The transceiver is now pro-
grammed.
