The PPC-J1900-104-R has several expansion connectors on the back side – 3 USB 2.0 connectors, 1 USB 3.0 connector, 2 LAN connectors, 4 COM connectors (4 RS232 connectors by default; COM1 and COM2 are optional RS485 connectors, which means there are 2 RS485), 1 HDMI connector, and 8 GPIO connectors.
Please note that a WiFi module does not come with the product by default, but it can be added. Use the menu in the top right corner of the product page to add it if you need it.
A 4G/LTE module can be added to the product, but we do not currently offer it in our shop. We recommend you buy it locally, and install it yourself, as it’s quite easy to add.
The 16 Pin 3.81mm screw terminal connector includes 8 GPIO and 2 RS232.
