Component Selection

After reading this chapter, you should understand the:

•

 module memory requirements for BASIC programming and be able to select 
the memory modules necessary for your application  

•

 concepts of connecting your module to the DH485 network and be able to 
select the components necessary for your application

•

 concepts of connecting a modem to the module and be able to select the 
necessary components for your application

Memory Requirements 
for BASIC Programming

The module uses the following types of memory modules during BASIC 
programming:

•

 a 32K byte battery backed RAM of which 24K byte is reserved to store BASIC 
programs and protected variables

•

 an optional 8K or 32K byte memory module to store BASIC programs 

 

IMPORTANT

Maximum user program storage space is 56K byte.  Battery 
backed RAM provides 24K byte and the optional memory 
module provides up to 32K byte.
