Chapter 1: Specifications
1.1.4 RS-232 (Serial)
The communication takes place with a transmission speed of up to 115.2 kbps,
regardless of the file format, eight data bits and a stop bit, but without a parity
bit. Limited hardware handshake (DSR) is possible.
1.1.5 RJ-45 (Interconnect)
CATx device communication requires a 1000BASE-T connection.
Connector wiring must comply with EIA/TIA-568-B (1000BASE-T), with RJ-45
connectors at both ends. All four wire pairs are used.
1.1.6 Fiber SFP Type LC (Interconnect)
Fiber device communication is performed via Gigabit SFPs connected to suitable
fibers fitted with LC connectors (see Section 1.2.2).
NOTE: The correct function of the device can only be guaranteed with SFPs
provided by Black Box.
CAUTION: SFP modules can be damaged by electrostatic discharge (ESD). Follow
ESD handling precautions.
1.1.7 SDI (Interconnect)
SDI device communication requires a mini coax connection with mini BNC
connectors or 3G SFPs with transmission speeds of 0.360 Gbps (SD-SDI, SMPTE
259M), 1.485 Gbps (HD-SDI, SMPTE 292M), and 2.70 Gbps (3G SDI).
1.2 Interconnect Cable
1.2.1 CATx
NOTE: A point-to-point connection is required. Operation with several patch fields
is possible. Routing over an active network component, such as an Ethernet
hub, router, or ServSwitch DKM FX, is not allowed.
• Avoid routing CATx cables along power cables.
• If the site has three-phase AC power, make sure that the CPU Unit and
CON Unit are on the same phase.
NOTE: To maintain regulatory EMC compliance, use correctly installed shielded
CATx cable throughout the interconnection link.
NOTE: To maintain regulatory EMC compliance, all CATx cables need to carry
ferrites on both cable ends close to the device.
Type of Interconnect Cable
The ServSwitch DKM FX requires interconnect cabling specified for Gigabit
Ethernet (1000BASE-T). Use solid-core (24 AWG), shielded, CAT5e (or better)
cable.
