6.7.1

Single-drop mode

In this operating mode, the read/write head first executes a command and then sends the
response. This may take a few seconds. The command syntax is identical to the syntax of the
read/write heads with the IDENTControl control interface, but does not contain the channel
number <ChanNo>.
Example
Command: <CommandCode> <CommandParameters> <CHCK> <ETX>
Response: <Status> <Data> <CHCK> <ETX>
You also have the option of replacing <CHCK><ETX> with #<CR>.
A new command can be sent only after a response to the previous command has been
received.
System Commands
Configure Interface CI
This command configures the timeout and the baud rate. The values are stored in the nonvola-
tile memory. Any modifications become active only after a reset has been performed. The time-
out is the time after which the read/write head no longer waits for characters in a command.
After the timeout expires, the user receives an error message. To deactivate the timeout, the
time must be set to "0".
The number of data bits is always 8. A parity bit is not used.
Command:
Response:
The following settings are possible:
<Timeout>: "0" ... "100" (x 100 ms, timeout in 100 ms steps)
<Baud>: "1,200" , "2,400" , "4,800" , "9,600" , "19,200", "38,400"
The default values are a timeout of "0" and a baud rate of "38,400".
Reset RS
This command interrupts all currently running commands. The device settings are reloaded
from the non-volatile memory.
