òòòòòòòò Scan Mode

The ACL0404A has a “Scan Mode” whereby each output automatically
cycles through and displays all inputs at a customer specified rate.
Activating the Scan Mode
There are 2 types of scan modes: individual scan and all scan. To enter
individual scan mode, a simple key sequence is entered on the keypad
[ Output Channel that you want to scan]. [/][Enter]
For example to scan output #1 press: 1.[/]e
This will begin scanning output 1 (it cycles through the inputs one at a time).
Each of the 4 output channels can be scanning independently of one another.
This means you can start scanning on one channel and then at some time
later, start scanning on another channel. Both channels will now be scanning
independent of one another. All scanning channels will scan at the same rate.
Enter all scan mode by key sequence:
[*].[/] [Enter]
This will start with output 1 on input 1, output 2 on input 2, output 3 on input
3 and output 4 on input 4.
Exiting Scan Mode
To exit the scan mode hit the Esc key on the keypad and this will cancel all
scanning whether it be individual scan mode or all scan mode. If the all scan
command has been issued, then scanning can be canceled by selecting any
input from any output via the keypad or by selecting an individual scan.
When individual scan mode is running on a channel, the way to cancel that
specific channel’s scan mode is to select an input for that channel from the
keypad.
Changing the Scan Timing
The time between transitions in scan mode is user definable (factory default
is 10 seconds). Connect the ACL0404A to a PC using a crossover DB9 serial
cable. Start up Hyper Terminal with the settings 1200, 8, none, 1, none. To
program the scan time, press PPP followed by the A through G
