OPERATIONS 4-2

O&M of the MCC-545B PACKET DATA RADIO

12/2000

4.1.2 Unit Name and Station ID

In command descriptions, the parameter "name" is the assigned Station name. The name is the

numeric Station ID. For more information on 545B operation as either a Remote or Master, refer

to Section 4.2.1. Station IDs, represented by "nnnn", can be assigned as follows:

1 – 245 Master Station

256 – 4095 Remote

Verify the ID is set correctly:

If it is not correct, refer to section 3.3 for procedures to set it.

4.1.3 HELP Command

Information about many 545B commands can be obtained via the HELP command. Typing

HELP with no parameters produces a single page display of an alphabetized command list. For

selected commands, typing HELP,command yields a summary explanation of how to use the

specified command. For example, typing HELP,ASSIGN explains the format to use when you

enter the ASSIGN command, along with a brief description of the command's function.

4.1.4 System Time and Date

The system calendar is maintained during power outages. If the date and/or time shown is

incorrect, the calendar can be initialized with the following commands:

DATE,mm/dd/yy

TIME,hh:mm{:ss}

The time of day maintained at the 545B is transmitted to all Remote Stations, thus maintaining

all units on the same time reference. If the time of day received at a Remote Station is greater

than two minutes from the internal Remote clock, the Remote sets its clock to the received time

of day.

To properly manage time, each Master and Remote must know how its own time zone relates to

UTC and the system time. This relationship is established by relating its time zone to known

reference points. UTC is always referenced to GMT; however, system time can be referenced to

any desired time zone. The time zone offset in the MCC-520B is defined with the following

command:

TIME ZONE,UTC offset,system offset
