The LayGO PXS-USB (PXSu) is a USB-to-Synchronous communication adapter.
From a user's point of view, it behaves like any of our other
synchronous communication cards. It is 100% compatible with the
API, so applications written to the API will run unmodified using this
device. The LayGO PXSu is compatible with the USB 2.0 standard and operates at
full speed (12 Mbps).
- Custom 1 line HDLC controller capable of speeds up to 4 Mbps.
- USB to HDLC data transfer and control program.
- Device Firmware Update (DFU) allowing field update to the
firmware and the netlist for the FPGA.
- Windows XP/Vista/2K3/2K8 USB device driver.
- LayGO API.
The PXSu looks like a cable with a USB connector on one side and a DB-25 connector
in the other. All of the electronics are housed inside the DB-25 connector case.
Most LayGO applications replace a modem. For this reason, the DB-25
connector in the PXS can be ordered with a female DB-25 connector wired as a DCE.
In this configuration, a DTE cable can be connected directly to the PXSu without
a "null modem" adapter.
See Cable - Female for detailed pin assignments.
