Cheat sheet

driver.cheatSheet()

What it is

The PUSR USR-W630 puts one RS-232 or RS-485 port on the network over WiFi or either of its two Ethernet ports. Serial data crosses TCP port 8899 unchanged, and the W630's own settings are read and written over UDP 48899.

Specs

Type: RS-232 / RS-485 serial device server, WiFi and Ethernet

Inputs: 1x RS-232 (male DB9) or 1x RS-485 (terminal block), not both at once

Mounting: Surface mount with shell positioning holes

Setup

First Use: Out of the box the W630 is a WiFi access point at 10.10.100.254 named USR-W630-xxxx. Its web page on port 80 signs in with admin / admin. Serial data crosses TCP port 8899. The serial port ships at 57600, 8, 1, None: set it to match the device you connect, then reboot. A PC serial port needs a null-modem cable.

Power Cycle: DC 5 to 36 V input. Remove power for ten seconds, or send REBOOT. Power cycle it if it stops answering the LAN search after a settings session.

Factory Reset: Hold the Reload key for 3 seconds or more until the Ready light goes off and on again, about 8 seconds.
