Parallel-PCI for CAMAC Control

Computer Automated Measurement and Control (CAMAC) is a long-established standard for data acquisition hardware, often used in the nuclear and particle physics fields. The good news about CAMAC systems (when enclosed in a chassis, they are called CAMAC “crates”) is that they seemingly last forever. The bad news is that they are very expensive, often […]

Raspberry Pi serial port: Ribbon or no ribbon?

The interest in an RS-232 serial port for the Raspberry Pi has LAVA considering making a simple GPIO-to-RS-232 DB-9 serial port board. This little item would plug onto the Raspberry Pi’s GPIO pin header, take the Raspi’s UART signals up to RS-232 levels, and present them on a conventional DB-9 (aka DE-9) connector. It would […]

RS-232 Serial Crossover Cables

The range of serial cabling includes crossover cables, sometimes called null modem cables. This post fills out the information on crossover cables, as at times confusion about them can cause systems not to work. When two pieces of Data Terminal Equipment (terminals, or DTEs) need to be connected to each other, or two pieces of […]

DNC Machining Control

Controlink Systems makes software designed for controlling machining and manufacturing equipment, over RS-232 (the standard interface). Direct Numerical Control (DNC) is used to control machining equipment when the machine itself does not issue the processing commands. Controlink Systems software meshes nicely with LAVA’s serial interfaces, whether PCI, PCIe, or Ethernet-to-Serial device servers.

Power over Ethernet (PoE) Serial Device Servers

Our popular one- and two-port serial device servers — the Ether-Serial Link 1-232-DB9, the 2-232-DB9, the 1-232-RJ45, and the 2-232-RJ45 — have now been spun into PoE (Power over Ethernet) versions. Because these device servers are designed to draw their power from the same Ethernet cable that is used for their Ethernet interface, there is […]
