Figure 12. Network-Wide Remote Diagnostics Setup

If a PC is connected to any radio in the network, intrusive polling

(polling that 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 locally, at the

radio.

A complete explanation of remote diagnostics can be found in GE MDS’

Network-Wide Diagnostics System Handbook. See the handbook for

more information about the basic diagnostic procedures 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 conﬁgure the diagnostic link protocol on the RJ-11 port.

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

DTYPE NODE command at each radio.
