IUH-F190-V1-*, IUT-F190-R4-V1*
Operation
System Commands
Configure Interface CI
This command configures the timeout and the baud rate. The values are stored in the
nonvolatile memory. Any modifications become active only after a reset has been performed.
The timeout 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.
Command:
Response:
The command must be executed after a configure interface CI or define function DF, so that the
changes become active.
Configuration Commands
See chapter 6.6 and see chapter 6.5
Read/Write Commands
See chapter 6.4
6.7.2
Multi-drop mode
In this operating mode, the read/write head immediately sends a confirmation that the
command has been understood. The read/write head then starts to execute the command. The
actual result of the command must be queried by polling the write/read head. The get data GD
command is used for this.
Note!
In multi-drop mode, the device address must be specified in each command.
In multi-drop mode, the command syntax differs from the syntax of the read/write heads with
the IDENTControl control interface through the addition of device address <DeviceNo> instead
of the channel number <ChanNo>.
