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 with GE MDS InSite software installed to the root

radio, or to one of the nodes, at the radio’s diagnostic port. (This PC

can also 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 can

be made using the information shown in Figure 13.

7. Start the GE MDS InSite application at the PC. (See the GE MDS

InSite User’s Guide for instructions.)

6.4 User-Programmable Interface Output

Functions

Two pins of the DATA INTERFACE can be manually activated through

GE MDS’ InSite NMS software. These two outputs (#1–Pin 22 and

#2–Pin 15) can be connected to compatible user-provided data devices.

The pins provide either a logic high or low depending on the last com-

mand from the

USER I/O SETTINGS in the Network Wide Radio Conﬁguration

screen of InSite. In this InSite window, clicking the

SET button sets the

output to high, and clicking on

CLEAR sets the associated output low. See

Figure 14 for a screen capture of the software controls.

One pin on the DATA INTERFACE can be configured as a digital

input. If

DIN ON is selected, Pin 16 becomes a digital input. The input is

set when 5 V is applied, and clear when grounded. The same physical

input can be queried as the analog input value on other InSite screens.
