The PPC-A9-215-C has several expansion connectors on the back side – USB 2.0, HDMI, LAN, CAN, RS485, and RS232 connectors. It also features a WiFi/BT module with an antenna and a 3.5mm audio connector. The 4G/LTE module is optional.
The WiFi/Bluetooth module is based on the Realtek RTL8723BS an 802.11bgn 2.4G single-chip that integrates Wireless LAN (WLAN) and an SDIO interface controller with integrated Bluetooth 2.1/3.0/4.0 controller. It combines a WLAN MAC, a 1T1R capable WLAN baseband, and WLAN RF in a single chip.
The CAN, RS485, and RS232 connector is a 16 Pin 3.81mm screw terminal connector (as you can see from the image). The speed of the RS232 and the RS485 port is up to 115200 Baud.
Since this display has 5 UART channels, they can be configured as RS232 or RS485. Bluetooth uses one UART channel – the default setting is 4 * RS232 + Bluetooth. Please contact us if you require a different configuration.
The 21.5-inch product features a 21.5’’ display with a 1920×1080 pixel resolution, 250 nits brightness, and a 10-point capacitive touch screen that offers stable and accurate control over the device, as well as great image clarity.
The PPC-A9-215-C has one 3.5mm Output/input connector and a 2W internal speaker when it comes to audio capabilities.
If your application requires a secondary display the HDMI port on the back of the panel allows the device to work in a double monitor configuration up to 1920×1080 pixel resolution at a 60Hz refresh rate.
