LineSelect® Manual Switch Model 7498 3-Channel BNC 75 Ohm Impedance Matched Ports with A/B Positions for Each Channel

Overview

The PathWay® Model 7498 Tri-Channel BNC 75 Ohm A/B Switch allows the user the capability of accessing two separate BNC devices, connected to ports A and B, through a controlling device/computer connected to the Common ports for each channel. The switch provides simultaneous channel control via the front panel rotary knob. The Model 7499 is enclosed in a 1U, full rack size, all metal, black chassis designed to provide EMI/RFI shielding and fit in a standard 19" rack.

• Great for Audio, Video Switch Applications!

• All BNC ports are impedance matched to support 75 Ohm equipment.

FEATURES OF THE MODEL 7498 BNC A/B SWITCH: 

• Each channel allows access to two BNC networks from one COMMON BNC network or device.
• Simultaneous control of all channels.
• Front panel rotary knob control.
• Switch supports 75 Ohm applications.
• Manually operated. No power required.
• Both the Center and Shell of the BNC interface are switched via break-before-make electromechanical relays.
• The switch ports are transparent to all data. 
• All BNC ports are impedance matched to support 75 Ohm equipment.
• Attractive all metal, black box packaging provides EMI/RFI shielding.

TECHNICAL SPECIFICATIONS:

• PORT CONNECTORS: (3) BNC (F) connectors labeled A, B, and COMMON for each channel.
• FRONT PANEL CONTROL: (1) Rotary switch on the front panel selects A or B position for all three channels.
• POWER: UL approved 100VAC-240VAC, 50Hz-60 Hz wall mount power module supplies 12 VDC, 500mA to the unit. Has 2-prong, US, non-polarized plug.
• DIMENSIONS: Rackmount 19.0" W x 1.75" H x 10.47" D (48.3 x 4.4 x 26.6 cm), (1U rack height).
• WEIGHT:  Approximately 5.7 lbs (2.6 kg)

OPTION: WIDE RANGE POWER MODULE

(Cat No 517277) CE, RoHS, and UL listed table mount power module, 100 VAC-240 VAC, 50Hz-60Hz for use in place of standard power module that is included with the unit. Has IEC 60320 C14 inlet.  Ideal for international applications.

PathWay® Model 7498 Tri-Channel BNC A/B Application w/Manual Rotary Control:

PathWay® Model 7498 Application diagram illustrates a COMMON device connected to the BNC COM port for Channel 1, Channel 2, and Channel 3. Each channel's COMMON device has access to two other BNC Interface devices connected to BNC ports A, and B. Simultaneously control all three channels from position A to position B or Position B to Position A via front panel rotary knob.

Typical Use Cases

Switching Audio/Video Signals

• Route a common video monitor or common recording device between two different video feeds (A or B).

• Useful in broadcast studios, control rooms, or AV production where multiple sources must be selected without manually re-cabling.

• All channels carry 75 Ω BNC signals with impedance matching.

Test & Measurement Setups

In labs sharing or switching test devices:

• Send a device signal to either primary or secondary test paths based on test stage.

• Remote contact closure lets automated test systems toggle paths without human intervention.

• Eliminates the tedium and wear of repeated manual cable switching.

Automated Equipment Control in Systems

Because of its remote contact closure interface:

• Integrate with PLCs, relay panels, or automated test sequences that need to switch signal paths programmatically.

• Provides dry contact logic for straightforward industrial control systems.

Redundancy / Failover Routing

• Switch to a backup signal source (B) if the primary (A) path goes down — either manually or under remote control.

• Useful in mission-critical systems where a primary video/data path must be switched to a standby device quickly and reliably.

Centralized Control for Multiple Channels

Instead of switching each BNC channel separately:

• One command toggles all three channels simultaneously — helpful if you have 3 related BNC paths (e.g., composite video reference audio sync) that must stay in sync when switching.
