USB keyboard mode can only output letters, numbers, punctuation;
USB secondary development mode can output any character without any restrictions
(development mode needs to be configured).
USB keyboard output has restrictions, other interfaces have no restrictions, can output text,
Chinese, traditional, special characters and even binary.
3, Android platform USB keyboard output, data will be lost.
Android system has anti-invalid input interference judgment. If the trigger time of 2 buttons
is too short, it will be judged as illegal input. Therefore, the configuration tool should be used
to set the press and raise time setting over 10ms.
If you are using it on Android, it is not recommended to output directly through USB. It is
better to use serial/secondary development.
4. Why does the device not give corresponding feedback after the network device sends the
return value according to the communication protocol?
1. Confirm whether the server can receive the data. If yes, whether the protocol mode is
modified or not, the feedback behavior of the network device is implemented based on the
protocol. Only in the protocol mode can it work normally.
2. The successful transmission behavior we configure in the configuration tool essentially
refers to the entire process of scanning data from the scanner, uploading the server, and
receiving the return value given by the server. If the successful instruction is sent directly,
obviously it cannot be determined as It is a successful transmission behavior.
5. When using a network device, the server can receive data, but it still fails after returning
the return value.
The network device has a timeout period. The default setting is two seconds. If the server
sends a return value to the device and the interval between scanning the data exceeds this
time, the device will determine that the return value will be received. This transmission is a
failure. The cause of this phenomenon is generally due to the poor network environment.
The solution is to properly adjust the timeout period. It should be noted that the timeout
period is set to a maximum of 5 seconds.
6, The device can not connect the configuration tool, but the scan code output is normal.
At present, the new RTX200 devices configuration tool cannot be used in common with the
old TX. Please confirm whether the device version is 5.5.X or 1.3.X, and then select the
corresponding version of the configuration tool.
In addition, it should be noted that the new version of the configuration tool currently does
not have a serial port tool and can only be directly connected through a USB connection to
the computer. If the serial port device needs to be configured, it can only be configured by
scanning code.
