The CX23-R data processor provides connections for sourcing input data channels through six connectors - one digital input/output, one GPS and three CAN.

The DIO connector provides pin connections for three sensor input lines, two current sinking output lines, one power output line and individual shield/ground connections for all five input and output lines.
Digital input channels have an input impedance of 10 KΩ, are over-voltage protected up to ±70 V and support user-defined static upper and lower thresholds in the range of ±5 V to a resolution of 20 mV. The -3 dB bandwidth is 4 MHz, with start of attenuation roll off at nominally 1 MHz.
Digital output channels can sink 350 mA to ground and are over-voltage protected up to ±60V. They are designed to drive LEDs, relays and other indicators and control at maximum update rates of 20 Hz nominally.
The DIO power supply provides power up to 3 W at user-selectable voltages of 5 V or 12 V (within ±5% accuracy).
The three CAN connectors support CAN channels and are functionally identical and functionally independent. The CAN ports are ISO 11898 CAN 2.0(A&B) compliant and support J1939 (limited to 8 byte data payloads). The CX23-R supports importing Vector CAN databases.
Each connector provides a switchable internal termination resistor. Each port provides passthrough power (from the CX23-R power supply source) limited to 1 A current draw. This can be used to power CAN devices such as the SomatCR 1609 CAN temperature measuring module.
The CX23-R supports baud rates of 1000K, 800K, 667K, 500K, 400K, 250K, 125K, 100K, 50K and 41.6K bps.
The GPS connector supports GPS channels and uses an RS232 serial port with additional control lines to communicate with the Somat EGPS-5HZ module. The CX23-R processes standard NMEA formatted GPS messages to provide navigation and time channels at 5 Hz update rates.
