In December 2025, JPS introduced the second-generation RSP-Z2 hardware platform.
Functionally identical to the first-generation model, the new RSP-Z2 is smaller, more portable, and even more ready to support the features that make the RSP-Z2 so popular.
| RSP-Z2 GEN 1 | RSP-Z2 GEN 2 | RSP-Z2 GEN2 Additional Information | |
| FRONT | FAULT, POWER LEDS | FAULT, POWER LEDS | More intuitive behavior and appearance; Power LED (instead of Fault) flashes during startup |
| CHANNEL FAULT, LINK, COR, PTT, SIGNAL LEDS | CHANNEL COR, PTT, SIGNAL LEDS | Channel Fault and Link lights were unused and added needless clutter; user interface supplies detailed feedback; COR (RX) and PTT (TX) LED colors now match user interface | |
| USB (1 FRONT, 1 REAR) | USB (2 FRONT) | Both USB ports in front for easier access | |
| POWER SWITCH | — | Removed to avoid accidental power interruptions | |
| LEVEL/VU METER | — | Removed due to limited utility and to reduce clutter; Signal LED can be used to achieve same results | |
| REAR | 2 RADIO CONNECTORS (DB-15 ANALOG) | 2 RADIO CONNECTORS (DB-15 ANALOG) | Comparable location |
| ETHERNET | ETHERNET | Location changed for easier access | |
| 12V DC CONNECTOR | 12V DC CONNECTOR | Cutout for easier location by touch | |
| GROUND | GROUND | Comparable location | |
| — | RESET BUTTON | Adds factory reset capability using hardware | |
| RS-232, HDMI | — | Ports were used exclusively during manufacturing; removal reduces physical hardware size |
- No functional difference exists between the capabilities and interoperability features of first-generation and second-generation hardware platforms.
- Second-generation RSP-Z2s can be used alongside first-generation devices without problem.
- You can manage either hardware version RSP-Z2 from the Z-Series Controller using Unity, download and install the same software updates, etc.
