HRX2
An incompatible HRX2 is a Version A HRX that has another HRX between it and the HLXC. This
is diagnosed by the HRX1. As a result, systems with two incompatible HRXs cannot be diagnosed.
The HLXC will set the alarm bit for the incompatible HRX2 and report “OLD-HRX-IN” in the
serial number of field of the HRX2 inventory. The MPU should activate the “Version Mismatch”
alarm and display the corrupted serial number.
HRX3
A third HRX is always incompatible. This situation is diagnosed by the HRX2. As a result, systems
with three HRXs when the HRX2 is a Version A cannot be diagnosed. The HRX2 will set the serial
number in the HRX2 inventory data to “3RD-HRX-IN.” The HLXC will set the alarm bit for the
incompatible HLXR. The MPU should activate the “Version Mismatch” alarm and display the
corrupted serial number. If the HLXC is a Version D or earlier, the alarm bit for dual repeater
incompatibility cannot be set. Thus, the MPU can only display the corrupted serial number.
Dual Repeater Compatibility Indicators
shows the various configurations that should be tested for dual repeater
compatibility issues. All legal configurations require extensive testing.
