To connect the host to the device using a serial connection such as RS-232 UART, configure the host’s serial port to use 115200 Baud, 8 Bit, No-parity, 1 Stop bit, and No flow control.
When using these connections, the host and device use SLIP format to send and receive MMS messages. For details, see section 2.6 How to Use SLIP Format (SLIP Only). The host software should always be ready to receive notification messages and command response messages from the device.
(BCR Only) When using the UART interface and the device is configured to be enable user action event notifications using Property 1.2.7.1.2.1 User Event Notification Controls Enable, the device cannot determine if it is connected to a host or not, therefore the device will continue reading barcode data even when not connected to a host.
