3.4 Data Bit
Data bits of WCS-232 only supports 8-bit.
If the host serial port has 7-bit data bit and Even/Odd parity, data bits can be considered and used as 8-bit combining
the data bit and parity bit and set parity to No parity.
3.5 Hardware Flow Control
WCS-232 is a device that is mounted on a host and transmits data wirelessly. WCS-232 has a buffer inside, and
stores data received from the host in this buffer and exports it repeatedly until successful transfer. Therefore, if the
wireless environment is not good, the transmission is repeated and the communication delay occurs.
If the buffer is full of data that has not yet been sent but additional data is received from the host, WCS-232 will
malfunction due to the buffer overflow. To prevent the overflow of limited buffers, WCS-232 works in the following
structure:
When using flow control, when the buffer is full, WCS-232 internally disables RTS, so that no more data is received
from the host until the amount of data occupying the buffer falls below a certain level. If flow control is not used, when
the buffer is full to a certain level, it empties the buffer for the next data received from the host, which means data
loss.
If the volume of data is not big, the probability of buffer overflow is low. But the greater the amount of data, the higher
the risk of overflow. Therefore, flow control is recommended to prevent data loss due to overflow.
*Note: The flow control does not work in Multi-drop mode.
3.6 Factory Reset
To reset all settings to the factory default value, press the reset button in Figure 3-1 for 1 second. The reset button
only works when power is on.
