3.2 RS-232 Commands
Each of the RS-232 commands is only a single letter in length. They are listed below, along
with their functional descriptions.
Command Function
Y Send model and software revision numbers, flow 90% and 100%
A/D values, and flow digital pot setting
K Receive Site ID strings into the CI-90
k Receive User ID strings into the CI-90
o Send the total time that the blower has been run
When the Y command is received the CI-90A responds by sending back the following:
CI-90A model number
Software Revision 2.07 software revision number
209 flow 90% A/D value; 209 is typical
221 flow 100% A/D value; 221 is typical
010 flow digital pot setting; 010 is typical
The “CI-90” is used by ID Pro to identify which model of CLiMET instrument it is
communicating with. All other information is provided for technicians and maintenance
personnel during calibration and repair.
When the K command is received the CI-90A responds by first starting a 28 second timer,
then storing the next 1500 characters it receives into non-volatile memory and setting the current
site ID to the blank (000). If the timer ends before 1500 characters are received, it determines the
last full 15 character ID that entered and sets it as the current site ID. This serves as an indication
to the user that something has malfunctioned, since ID Pro always sends 1500 characters
regardless of how many ID’s are sent, and it routinely does it in about half the timer duration.
When the k command is received the CI-90A responds by first starting a 4 second timer, then
storing the next 90 characters it receives into non-volatile memory and setting the current user ID
to the blank (00). If the timer ends before 90 characters are received, it determines the last full 9
character ID that entered and sets it as the current user ID. As with the K command, if the current
user is not set to blank (00), something has gone wrong with the download.
When the o command is received the CI-90A responds by sending back the following:
hhhhh hours, mm minutes of blower run time. h and m are numerals 0-9
This command is normally used by a technician to determine the amount of run time on the
blower.
3.3 CI-9x Loader
CI-9x Loader (P/N 95035101) is a separate program that allows the user to load all 100 site
ID’s and all 10 user ID’s from a PC without having to use the CI-90’s alpha entry menu.
Although the CI-90’s alpha entry screen is a convenient, stand-alone way to enter ID names, it is
