7.2 Performing Network-Wide Radio Diagnostics

Radios in a network can be remotely polled by connecting a laptop or

PC running MDS InSite diagnostics software to any radio in the net-

work. Figure 35 shows an example of a setup for performing net-

work-wide remote diagnostics.

If a PC is connected to any radio in the network, active messaging

(polling which briefly interrupts payload data transmission) can be per-

formed. To perform diagnostics without interrupting payload data trans-

mission, connect the PC to a radio defined as the “root” radio. A radio

is defined as a root radio using the

DTYPE ROOT command (Page 42)

locally, at the radio.

For more information, see the InSite Radio System Management Soft-

ware User’s Guide. A complete explanation of remote diagnostics can

be found in MDS’ Network-Wide Diagnostics System Handbook. See

the Handbook for more information about the basic diagnostic proce-

dures outlined below.

1. Program one radio in the network as the root radio by entering the

DTYPE ROOT command at the radio.

2. At the root radio, use the DLINK ON and DLINK [baud rate] commands

to enable network-wide diagnostics and set the baud rate at the diag-

nostics port.

3. Program all other radios in the network as nodes by entering the

DTYPE NODE command at each radio.
