It ships with a software installation CD that will install drivers, a users manual, a useful Help file, as well as the "Keyspan USB Serial Adapter Assistant". X-Rite recommends the "Keyspan model USA-19HS" USB to serial adapter.

In the event that a customer has purchased a serial device and is attempting to connect it to a PC that does not have a serial port but does have a USB port, a USB to serial adapter should work. Out of Production Products - Find Your UpgradeĬOM Port Mapping with Keyspan USB Serial Adapter.The Digitrax system was a Chief, DT100IR throttle, and various decoders on the layout. Java access to the USB serial adapters was via Patrickīeard's Macintosh implementation of m. Java application created with CodeWarrior 4.1.0.3 build 661.

The tests were done with a PowerBook G4 400MHz, Mac OS 9.1. The USB serialĪdapter was not reporting any received characters to the Macintosh. Getting up to 6V, marginally OK, but it was not going below ground. The following picture is the received data, nominallyĪn RS232 signal of at least +/-6 volts, from the MS100. Providing auxiliary +/- 9V power to the MS100, without using the output lines as a Not to power the receive level shifter in the MS100. This was a large enough swing to drive the LocoNet itself, but The following picture shows the transmit data levels from the Keyspan adapter. This was notĮnough to power the MS100 during receive. The second problem was that the serial port outputs were only +/- 5V. The control line from the second port to provide the other level. Since there are two ports, I build a small adapter to use This means that the serial port can only provide one of the two + and. The initial problem was that the USB adapter provides only one control line output Keyspan Dual Serial Adapter P/N USA-28X Summary: This did not work. Note that I didn't test the level input from the MS100 (DSR, CTS). Have, and the test program was immediately able to communicate with the LocoNet. I connected it through a DB9 female to DB25 male adapter cable that I happened to Separately controlled to provide + and - voltage to the MS100. Note that there are both RTS and DTR outputs these can be This adapter provides a DB9 male plug, pinout available from the This was actually the second USB serial adapter I tried, after the Keyspan Dual SerialĪdapter (see below). Details Keyspan PDA adapter P/N USA-19 Summary: This worked fine. This was not enough to power the MS100 during receive. Problems: the USB adapter provides only one control line output, and the serial port
There seem to be multiple versions of the adapter, with slightly different model numbers,Īnd it could be that some of them will only work at speeds of up to 56,000 baud. We've had a report that this PDA adapter can't work with a LocoBuffer at 57,600 baud. "Keyspan High Speed Serial Adapter" Part# USA-19QW is the same unit. Unfortunately, this adapter is no longer made. Summary Keyspan PDA adapter P/N USA-19 Summary: This worked fine. Has graciously provided a schematic of their level shifter which is thought to be very Digitrax has not published a schematic, but Bill Robinson of Team Digital The MS100 is a passive level shifter that gets its power from the control leads in the We strongly recommend to use a better solution to connect a computer toĪ LocoNet, such as the LocoBuffer USB or the Digitrax PR3/ PR4. This page describes tests of two USB-to-serial adapters, done circa 2010 using the Hardware Support: Keyspan USB connections Layout Automation Use JMRI to automate parts of your layout and operations: Tools JMRI tools for working with your layout:
