Edwards 4-USBHUB — multi-port USB hub module for EST4 panels and annunciators.
EST4 CPUs carry only a few USB connectors, so a job needing a supervised event printer plus a laptop connection plus a coder runs short. The 4-USBHUB adds ports in a half-footprint module space, and its isolated Type A ports extend ground-fault detection to a system printer.
- Two isolated Type A host ports, four non-isolated Type A host ports, one Type B device port
- Data rates to 480 Mbps; RS-232 terminals for a CDR-3 coder, 24–12 AWG
- 44 mA with no non-isolated port used; 129 mA per non-isolated port; 560 mA fully loaded
- Half-footprint mounting in CAB series and 4-ANNMT series enclosures
- 32 to 120 °F (0 to 49 °C), 0–93% RH non-condensing; UL, ULC, FM, CSFM
- Supplied with the 4-CABLUSBSM USB 3.0 A-B cable, approx. 29 in (750 mm)
This is an EST4-platform module, not an EST3 or EST3X part. Its J1 connector lands on a 4-CPU, 4-ANNCPU, 4-NET-AD, 4-CPU-GRPH or 4-FWAL and must always be the last device on that data bus.
