The ZRS series RS-232 interface modules make it easy to communicate RS-232 data to NCD devices. Based on the MAX3232 interface chip, the ZRS converts RS-232 data to 3.3V standard required for NCD Industrial Devices. The ZRS includes 3 on-board LEDs used to indicate Power, TX, and RX communications for easy reference. The ZRS was designed specifically for use with NCD Industrial series devices, including ProXR, ProXR Lite, Fusion, Reactor, Taralist, Pulsar, and many more. The ZRS is available in 3 versions:
There are three RS-232 connection options available for this controller.

The ZRS-A provides RS-232 communications access via 3 screw terminals for Tx, Rx, and Ground connections. This version is specified for use in direct wired installations.
The ZRS-B provides RS-232 communications access via a DB9 Female connector. This version is specified for use for direct connection to PCs with a standard serial interface.
The ZRS-AB provides RS-232 communications access via 3 screw terminals for Tx, Rx, and Ground connections. This version also includes a off-board DB9 female connector and 3 wires (6″ or 152mm in length) that connect the Ground, Tx, and Rx lines to the ZRA-A module. This version is specified for use in installations where the DB9 connector needs more flexibility in mounting locations.
This video demonstrates many communication modules similar to the Digi XBee industrial wireless modules. This video shows Ethernet, WiFi, Bluetooth, Key Fob, RS-232, and Drop Net (Similar to RS485), all of which fit into NCD Controllers equipped to use the Digi XBee interface. Mobicle WiFi Interface provides an encrypted IoT interface Solution. Mobicle Provides a Universal Graphical User Interface (GUI) for all IoT devices.

Whether you need the power of ethernet or the simplicity of RS-232 we have something to fit your application.
The NCD RS-232 Serial communications module is compatible with standard RS-232 signals (+/-10VDC), which are not directly compatible with UART signals from a microprocessor. If you are working with Arduino, Microchip PIC, or other common microcontroller, a communications module is not required. Microcontrollers will directly talk to the on-board processor of all NCD controllers.
