Key Radio

Transmitter

KEY

This command activates the transmitter. See also the DKEY command.

Operation Log LOG [CLR]

This command displays or clears a list of the last 800 operating changes,

called “system events.” These events include alarm notifications, as

well as normal operator actions such as turning the power on or off. In

many cases, the events leading up to a failure can be reviewed to help

determine the cause of a problem.

Entering the

LOG command without any parameters displays the entire

event history. Entering

LOG CLR or LOG CLEAR clears all current events

from the log history.

Multiple-Drop

Address

MADDR [NONE, 1–255]

The radio’s Multi-Drop Address uniquely identifies this radio on an

RS-232 COS (code-operated switch) bus connected to the rear panel’s

DIAGNOSTIC PORT, J1. The unit’s address initially is set as NONE, for a

computer directly connected to the

DIAGNOSTIC PORT of one radio.

MADDR addresses can range from 1...255. The master station will ignore

diagnostic messages sent to other Multi-Drop Addresses. With the

MADDR address programmed, MDS’ InSite™ network management

system program can poll master stations through the COS bus to receive

diagnostic information of the master unit itself. The

MADDR command

will work on MDS x790 master stations with software version 1.7 or

later installed. For more details, please see “Connecting Multiple Mas-

ters at One Site” on Page 30.
