Frequently Asked Questions - B140-004 Tripp Lite
How do I set up the Tripp Lite B140-004 extender?
Connect your VGA source to the input port on the transmitter, then run Cat5/5e/6 cables from the four output ports to compatible receivers. Attach a monitor to each receiver, connect the power adapter to the transmitter, and all units will power on automatically.
What is the maximum distance supported?
The B140-004 can transmit signals up to 500 ft (152 m) over Cat5 or better cable. For best performance, use high-quality solid-wire Cat5e/6 and keep cables away from power lines to minimize interference.
Does the B140-004 support audio transmission?
Yes, it supports stereo audio alongside the VGA signal. The audio input is a 3.5mm jack on the transmitter, and the receivers provide a matching 3.5mm output for speakers or monitors.
Can I mix different monitor resolutions across the four outputs?
The signal is split from a single source, so all outputs share the same native resolution. The maximum supported resolution is 1920 x 1200, but each monitor must be capable of displaying that resolution if you intend to run them all at the same time.
What type of cable is required?
Use Cat5, Cat5e, or Cat6 UTP/STP cable with RJ-45 connectors. For long runs, solid conductor cable is recommended over stranded patch cords for better signal integrity.
Does the extender require a separate receiver unit?
Yes, each of the four remote locations needs a compatible receiver (like Tripp Lite B140-000R). The B140-004 is a transmitter that only sends the signal to those receivers.
How many remote displays can I connect?
The B140-004 has four output ports, allowing you to connect up to four separate displays simultaneously when paired with four receivers.
Is the unit compatible with 4K video sources?
No, this model supports VGA signals up to 1920 x 1200, which does not include 4K (3840 x 2160). For 4K HDMI over IP, consider Tripp Lite models specifically designed for 4K distribution.
How do I troubleshoot no signal on a remote display?
First check that all connections are secure and the transmitter is powered. Verify the Cat5 cable is terminated with the same pinout on both ends (TIA/EIA-568B is recommended). Also ensure the receiver is powered if it requires a separate adapter, and try a short known-good cable to isolate length issues.
How do I clean and maintain the extender?
Disconnect power before cleaning. Use a dry, lint-free cloth to wipe the housing. Do not use harsh chemicals, sprays, or immersion in liquids. The device requires no routine internal maintenance—just keep it free of dust and debris.
