The Parallax Control Processor device is accessible by hardwired ethernet, or by its on-board access point.
The access point default SSID is: CM4-<macAddress>
Default password: <serialNumber>
Once connected to the AP, open a terminal window and ssh into the device:
ssh pi@<ipAddress>
ssh pi@cm4-<macAddress>.local
Note: if you receive a connection warning, you may need to delete/modify your known hosts file on your computers hidden .ssh folder.
WIRELESS ACCESS POINT AND ETHERNET PORT CONSIDERATIONS: The on-board access point contains a router with DHCP server. The controller is set to hand out DHCP addresses to devices connecting via the onboard access point, such as your laptop or a wireless touch panel. These devices will be given an address on the 192.168.10.0 subnet by default, which must remain different from the wired nic subnet. The ethernet port is by default set as DHCP. If no DHCP server is preset, it will revert to a link local address.
Hardwired ethernet devices: which are to be controlled, should be set with static addresses. The controllers wired ethernet nic does not contain a dhcp server. Be sure to set the control processor, and the devices to control on the same subnet.
Wireless touch panels: if connected by the on-board access point will be able to communicate with devices on the wired nic, wireless tablets will be assigned an address by the controllers dhcp server.
Managing Device from Access Point: You may connect directly to the on-board ap to load code and manage the device the same as if you set up a wired network. This is very convenient for programmers as they can update projects wirelessly from their laptop without having to break out any dongles, adapters or usb cables.
