Template:VALT Keypad 3 - Old

Configuration

Creating the Cable

1. Cut two 15 foot lengths of 22/8 cable
2. Use a 2x20 pin connector, a 2x3 pin connector, and a 1x7 pin connector, crimp and connect as shown below

How to Connect

A GPIO cable will be connected to the processing unit. Connect the cable as shown below. Ensure that the black cable in the 2x20 pin connector aligns with the white cable on the GPIO cable. Attach the wiring to the physical keypad as shown

DHCP

The VALT Keypad will automatically pull an IP address from DHCP. The IP address can be obtained by reviewing DHCP leases on the associated DHCP server. The hostname of the device is Keypad.

Static

If no DHCP server is available, the VALT Keypad will default to a static IP address of 192.168.0.92.

Manual

The IP address from the keypad may also be obtained directly by plugging in a keyboard and running the following command from the console:

ifconfig | more

The IP address will be listed under interface eth0.

Manually Setting an IP Address

In order to set the IP address manually, connect to the Keypad using the ivsadmin user. The ivsuser account cannot change any settings. If connecting from the console, type the following to change accounts. There will be prompt for the ivsadmin password.

su ivsadmin

1. Type the following, and press Enter:

   sudo nano /etc/dhcpcd.conf

2. Scroll down until to the section for interface eth0.
3. Remove the # at the start of the lines for static IP, static routers, and static domain_name_servers.
4. Update the IP configuration to reflect the correct settings for the environment.

   

5. Comment out the remaining lines in the file by adding a # to the start of the line.
