Questions
- What is the maximum resolution supported?
- The EXT-HDMICAS70MRX is HDMI 2.0 / HDCP 2.2 compliant, supporting up to 4K x 2K @ 60Hz (4:4:4 HDR), matching the EXT-HDMICAS70M transmitter it pairs with.
- What is the maximum distance per run?
- The unit connects over a single Cat6, Cat6a, or Cat7 run of up to 70M (230 ft.).
- How does this unit connect into an existing cascaded system?
- Connect a Cat6/6a/7 cable from the EXT-HDMICAS70M TX, or another RX's cascade connection, to this unit's RJ45 IN, up to 70M per run, then connect the display to HDMI OUT.
- How many of these units can be added to one system?
- Up to 9 additional EXT-HDMICAS70MRX units can be added to a single EXT-HDMICAS70M TX, for a total of 10 display endpoints.
- What cable is required?
- A single Cat6, Cat6a, or Cat7 cable, STP recommended with proper grounding, kept away from power cables.
- What are the unit dimensions and weight?
- The RX is housed in a 4.17 x 3.90 x 1.03 in (106 x 99 x 26.2mm) aluminum chassis weighing 0.46 lb (210g).
- No signal on the display. What should I check?
- Verify the RJ45 cable from the TX or upstream unit does not exceed 70M, confirm the EXT-HDMICAS70M TX is powered and active, check the HDMI cable to the display, and power-cycle this RX unit.
- The display shows the wrong resolution. What should I check?
- Power-cycle the RX with the display connected so it can re-read EDID and adapt, and ensure the display is powered on before powering the RX.
- What is the benefit of independent per-receiver EDID management in a multi-display job?
- Each added receiver reads its own display's EDID, so a job mixing display types, such as a 4K monitor and a 1080p projector, does not require forcing every screen to a single output resolution.
- Does adding this receiver require reconfiguring the rest of the system?
- No. The unit is plug-and-play with no configuration required; it independently reads the connected display's EDID on power-up.
