Prerequisites

To program radios using the RSS, we recommend a basic working knowledge

of the following:

•

Microcomputers

•

The radio’s available features (Refer to the appropriate Radio Operator’s

Manual.)

•

Your customers’ needs

•

MS-DOS operating system, version 5.0 or later

The ASTRO RSS requires a minimum of 510 kilobytes of free RAM to run. (The

DOS CHKDSK command can be used to determine the amount of free RAM

available on your computer.) DOS 5.0 is required. It is also strongly

recommended that this RSS be run on an IBM

compatible computer with an

80386 or newer processor with the following minimum conﬁguration:

•

80386 CPU or higher

•

DOS 5.0 or higher (with DOS running in high memory)

•

4 Megabytes of RAM or greater

The installation program will determine if your system has an adequate

amount of memory available (4M) and a 386 (or 486) CPU for extended

memory operation. If these are present, the RSS will be installed.

The powerful features and extensive ﬂexibility of new radio families require

much more codeplug data validation than in the past. For complex

conﬁgurations, it is recommended that the RSS be executed from a RAM disk.

This will reduce execution time signiﬁcantly. To conﬁgure your computer with

a RAM disk, you need to modify your CONFIG.SYS ﬁle with a statement. The

sample statement below is required to run the RSS in DOS 5.0:

DEVICE=C:\DOS\RAMDRIVE.SYS 4096 512 1024 /E

The following lines should also be added to the CONFIG.SYS ﬁle if necessary:

device = c:\dos\HIMEM.SYS

device = c: \dos\EMM386.EXE OFF

Files = 30

Note:

The DOS MEM command can be used to determine the amount

of available memory in your computer (i.e. type c:\dos\mem.

The

location of MEM.EXE may differ on your machine

.) If the command reports

3000K or more of available extended memory, you can run the ASTRO

RSS.
