4.4.2 COMMA DELINEATED ASCII

Comma Delineated ASCII strips all IDs, leading zeros, unnecessary decimal points and trailing zeros, and plus signs. Data points are separated by commas. Arrays are separated by Carriage Return Line Feed. Comma Delineated ASCII requires approximately 6 bytes per data point. Example:

1,234,1145,23.65,-12.26,625.9 1,234,1200,24.1,-10.98,650.3

4.5 STORAGE MODULE (SM192/716)

The Storage Module stores data in battery backed RAM. Backup is provided by an internal lithium battery. Operating power is supplied by the CR10 over pin 1 of the 9-pin connector. When power is applied to the Storage Module, a File Mark is placed in the data (if a File Mark is not the last data point already in storage).

The File Mark separates data. For example, if you retrieve data from one CR10, disconnect the Storage Module and connect it to a second CR10, a File Mark is automatically placed in the data. This mark follows the data from the first CR10 but precedes the data from the second.

The SM192 has 192K bytes of RAM storage; the SM716 has 716K bytes. Both can be configured as either ring or fill and stop memory.

4.5.1 STORAGE MODULE ADDRESSING

The capability of assigning different addresses to Storage Modules allows 1) multiple (up to 8) Storage Modules to be connected to the CR10 during on-line output (Instruction 96), 2) different data to be output to different Modules, and 3) transfer of data from a Module that is left with the CR10 to a Module that is hand carried to the site for data transfer (*9 Mode).

Storage Modules are assigned addresses (1-8) either through the *9 Mode or through Telecommunications (SM192/SM716 Manual). 1 is the default address when the Storage Module is reset, and unless you are using one of the features which require different addresses you need not assign any other address.

Address 1 is also a universal address when sending data or commands to a storage module with Instruction 96, *8, or *9. When address 1 is entered in the *9 Mode (default) or in the device code (71, Table 4.2-1) for Instruction 96 or the *8 Mode, The CR10 searches for the Storage Module with the lowest address that is not full (fill and stop configuration only) and addresses it. In other words, if a single Storage
