System Monitor Manual (BN Document 89604, table 1) for specific jumper configurations. 

Table 3 in Section 2.4 lists the SDI/DDI compatible monitor firmware part numbers. 

The Mixed System can be upgraded to an SDI/DDI System, by changing the backplane, 

power supply, and the firmware in each of the monitors. 

2.1.3 SDI/DDI System 

This generation of the 3300 System uses 3300/03 System Monitor. The System Monitor, 

Power Supply, and Backplane are all SDI/DDI-compatible, with the System Monitor 

configured with or without internal SDI/DDI communications and the firmware in each of 

the monitors is SDI/DDI compatible. 

NOTE: The System Monitor must be configured correctly with jumpers depending upon 

the external Communication Processor that is being used. The DDM, TDM, and PDM use 

a different static interface than the SDIX/DDIX, TDIX, and TDXnet™ communication 

processors. Refer to the System Monitor Manual (BN Document 89604, table 1) for 

specific jumper configurations. 

The SDI/DDI System is compatible with the following Bently Nevada Communications 

Processors and monitoring software packages: DDM CP, TDM CP, SDIX/DDIX CP, TDIX CP, 

TDXnet™ CP, DDM/TDM Software, DDM2/TDM2 Software, System 64 Software, and 

DM2000 Software. 

2.1.4 TDe System 

This generation of the 3300 System uses 3300/02 System Monitor. The Power Supply, 

Backplane and firmware in each of the monitors must be SDI/DDI compatible. 

The TDe System is not compatible with any external Communications Processors as they 

are not required for TDe to directly interface to System 1® Software. 

2.2 System Identification 

The following sections discuss how to determine the configuration of your 3300 System. 

You may use the following steps as a guideline to identify your monitoring system. 

• Examine the front panels of the System Monitor and Power Supply and check the Power 

Input Module on the back of the rack. Use the information in Sections 2.2.1, 2.2.2 and 

2.2.3 to determine your system configuration. 

• If there is any question as to the system configuration after completing step 1, use 

Section 2.3 to identify the backplane. The backplane determines whether the rack is an 

SDI/DDI System rack or an Original System rack.

Note: The new backplane cannot be used with the old power supplies and the old 

backplane 

cannot be used with the new power supplies. They BOTH must be updated at the 

same time. 

• Use Section 2.4 to determine the firmware identity on individual 3300 monitors. The 

firmware in some early 3300 monitors is not compatible with newer generation data 

interfaces (SDIX/DDIX, TDIX, TDXnet™ communication processors or TDe). Similarly, 

some new multi-channel monitors are not compatible with older external 

Communications Processors. See Section 3 for compatibility information.

2.2.2 Mixed System 

• Consists of an 

original system 

with a 3300/03-01 

System Monitor, a 

3300/10 or /11 or 

/14 Power Supply, 

an original 

backplane, and one 

of the original 

Power Input 

Modules shown in 

Figure 2. 

• In this 

configuration the 

3300/03-01 is a 

replacement for 

the 3300/01-01 

System Monitor. 

Note that only two 

Keyphasor® 

transducers, Key ∅® 

1 and Key ∅® 2 are 

available. 

• Se Appendix A for 

the list of hardware 

upgrade kit part 

numbers and/or 

contact your Bently 

Nevada 

representative to 

upgrade a system.

3. System Compatibility 

Use this section to determine which components will or will not work in your system. Refer 

to Section 2 and/or Table 2 to determine which system configuration you have. 

See Table 4 for compatibility between each System Monitor and the different 

Communications Processors and Software. 

See Appendix A for the list of hardware upgrade kit part numbers. 

See Appendix B for a list of firmware upgrade kit part numbers for the different monitors. 

3.1 Mixed System Compatibility Issues

• If a Mixed System is being used with a DDM, TDM or PDM CP, the firmware in the 

individual monitors does not need to be SDI/DDI compatible. 

• In order for the Mixed System to be compatible with the external communication 

processors (SDIX/DDIX, TDIX or TDXnet™ CP) and DM2000 software, the firmware in 

all of the monitors must be SDI/DDI compatible. See Table 3 for SDI/DDI compatible 

firmware. 

3.2 Additional Compatibility Issues

3.2.1 Monitors 

• The original firmware in the 3300/17, 3300/36, 3300/39, 3300/40, 3300/52, 3300/53, 

3300/54, 3300/75, 3300/80, 3300/81, 3300/85, and 3300/95 monitors is SDI/DDI 

compatible. 

• The 3300/75, /80 and /81 monitors support SDI(X)/DDI(X), TDIX, and TDXnet™ CPs 

only. 

• The 3300/75, /80 and /81 monitors are compatible with only the 3300/01-01, 3300/02 

and 3300/03-XX System Monitors. 

• The 3300/90 Diagnostic Instrument and the 3300/60 Vector Monitor are not supported
