Extron IPCP Pro 555Q xi (part number 60-1917-01A) — a half-rack-wide IP Link control processor combining the 550 xi's extensive serial, relay, and Flex I/O count with a dedicated AV LAN and doubled program memory.

The 555Q xi adds a second Gigabit NIC for AV LAN traffic isolation and 2 GB of SDRAM on top of the 550 xi's eight serial ports, eight programmable IR/serial ports, eight relays, four Flex I/O channels, and four switched 12 VDC outputs — all from an internal power supply in a half-rack enclosure.

Key Capabilities

• 2 Gigabit NICs: 1 LAN plus 1 dedicated AV LAN for network segmentation
• 2 GB SDRAM / 8 GB flash, double the 550 xi's program memory
• 8 serial ports, 8 programmable IR/serial ports, 8 normally open relays
• 4 Flex I/O channels plus 4 switched 12 VDC outputs (up to 40 W total)
• Internal power supply, no external brick to manage

Where It Is Used

Large AV-over-IP installations that need both extensive hardwired I/O and network segmentation use the 555Q xi's dedicated AV LAN alongside its full serial, relay, IR, and Flex I/O complement to control an entire facility from one processor.

Specifications at a Glance

• Network: 2 Gigabit NICs (1 LAN, 1 AV LAN)
• Serial: 2 RS-232/422/485 + 6 RS-232; IR/Serial: 8 ports
