The Scan (SN) command allows you to define the debounce time (in milliseconds) for
external sequence selection inputs. The debounce time is the amount of time that the
sequence inputs must remain constant for a proper reading from a remote controller, such
as a programmable logic controller (PLC). If you are using a PLC you should change the
debounce time to match the on time of the PLC outputs.
This command allows you to select the best possible trade-off between noise immunity
and speed for a given application. If you make your scan time too short, the TQ10X may
respond to an electrical glitch. If you issue the Scan command with only a device address
(1SN), the controller will respond with the current debounce time (*SNn).

This command turns the RS-232C echo (transmission of characters received from the
remote device by the TQ10X) on and off.
SSAØ = Echo on
SSA1 = Echo off
In the Echo On (SSAØ) mode, characters that are received by the controller are echoed
automatically. In the Echo Off (SSA1) mode, characters are not echoed from the TQ10X.
This command is useful if your computer cannot handle echoes. In a daisy chain, you must
have the echo on (SSAØ) to allow controllers further down the chain to receive
