A complete explanation of remote diagnostics can be found in MDS’
Network-Wide Diagnostics System Handbook (MDS P/N
05-3467A01). 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.
4. Use the
DLINK ON and DLINK [baud rate] commands to configure the
diagnostic link protocol on the RJ-11 port of each node radio.
5. Connect same-site radios using a null-modem cable at the radios’
diagnostic ports.
6. Connect a PC on which MDS InSite software is installed to the root
radio, or to one of the nodes, at the radio’s diagnostic port. (This PC
may be the PC being used to collect payload data, as shown in
Figure 12.)
To connect a PC to the radio’s
DIAG. port, an RJ-11 to DB-9 adapter
(MDS P/N 03-3246A01) is required. If desired, an adapter cable
may be constructed from scratch using the information shown in
Figure 13.

7. Launch the MDS InSite application at the PC. (See the MDS InSite
User’s Guide for instructions.)
7.3 Bench Testing Setup
Figure 14 shows a sample test setup that can be used to verify the basic
operation of transceivers in a shop setting. The test can be performed
with any number of remote radios by using a power divider with the
required number of output connections.
