Ethernet Connection
DoD Ethernet-only Vision Miner 22IDEX V4 - verify WiFi removal, Regular Ethernet (DHCP) vs Ethernet to PC (static), chamber LEDs, Web Interface access, and network mode setup.
DoD-configured Vision Miner 22IDEX V4 printers use Ethernet only (no WiFi module). This guide covers verifying WiFi module removal, connecting via Regular Ethernet (DHCP) or Ethernet to PC (static IP), understanding chamber LED status, and accessing the Web Interface.
Before you begin - safety and risk
Read the Safety - Before You Begin article to understand the hazards involved in working on the Vision Miner 22IDEX V4 - including electrical, thermal, mechanical, and chemical risks. All procedures in this wiki are provided as recommendations only. By choosing to follow any procedure, you do so at your own risk.
Tools and Materials
- Vision Miner 22IDEX V4 (DoD Ethernet-only build)
- Ethernet patch cable (Cat5e or better)
- Regular Ethernet: managed or unmanaged switch or router with a free port and DHCP
- Ethernet to PC: PC or Mac with Ethernet or a USB-Ethernet adapter, plus rights to set a static IPv4 address
- Physical access to the rear electronics bay (control board and WiFi socket)
WiFi module removal
Unplug mains before the rear door
Power off from the switch, unplug the printer, then open the left-hand rear door (seen from the back). Do not reach into the bay with mains present.
- Power off and unplug the printer.
- Open the left-hand rear door.
- On the control board, next to the Ethernet jack, the WiFi module socket must be empty.
If a module is installed: disconnect the antenna if fitted, pull the board straight up, store it ESD-safe, close the door.
Facility policy usually forbids operating DoD machines with WiFi enabled - remove the module before you join a production network.
When empty, close the door and proceed.
Choose the link type
| Mode | Cable path | Addressing | Typical use |
|---|---|---|---|
| Regular Ethernet | Printer > switch/router | DHCP from the LAN | Several PCs need the printer; normal building LAN |
| Ethernet to PC | Printer > one PC only (no switch in between) | Printer 192.168.1.50, PC 192.168.1.51, mask 255.255.255.0 | No DHCP, or policy needs an isolated link |
After a successful setup, the printer reuses the same mode after each reboot until you change it in Macros > System > Settings > Network or via the touchscreen prompt.
- Regular Ethernet: go to Regular Ethernet (DHCP).
- Ethernet to PC: go to Ethernet to PC.
LED status indicators
After powering on and waiting 60 seconds, chamber LEDs indicate connection status:
| LED Color | Connection Method | Status | Action |
|---|---|---|---|
| ?? Yellow | Network Switch/Router | Connection successful via DHCP | Save configuration on touchscreen |
| ?? Blue | Direct PC Connection | Connection successful (static IP) | Save configuration on touchscreen |
| ? White | Any | Previously saved mode active | Normal operation - no action needed |
| ?? Red | Any | Connection failed | See Troubleshooting |
Regular Ethernet (DHCP)
Complete WiFi module removal first.
- Power off the printer. Connect Ethernet from the printer jack to a LAN port on the switch or router. Seat the plugs fully; confirm link LEDs on the port.
Verify internal connection:
Open the rear electronics bay and verify the Ethernet cable is properly seated in the control board's Ethernet port. Check that the connector is fully inserted and the link LEDs are lit.
-
Power on. Watch the chamber LEDs for 60 seconds (longer on slow switches is OK).
- Yellow - DHCP path succeeded; continue.
- Red - failed; see Troubleshooting.
First minute on the wire
The board negotiates the link, then requests DHCP. Do not call it failed until the full interval has passed.
- On yellow, the touchscreen shows Network Connected with an IP and asks whether to remember the mode. Note the IP.
- On a PC on the same subnet, open a browser to the address from the touchscreen (for example
http://192.168.1.150) and confirm the Web Interface loads.
Hostname vs IP address
http://22idex.local often works where multicast DNS is allowed; on locked-down LANs use the numeric IP.
-
Only after the Web Interface works, tap Save network configuration on the printer.
-
Cold boot test: power off, on, wait 60 s. White chamber LEDs mean the saved Regular Ethernet profile is active. Yellow or red means the save did not stick - open the Web Interface, go to
Macros > System > Settings > Network, choose Enable Ethernet Mode, reboot, and recheck.
Ethernet to PC
Use this when you cannot place the printer on a DHCP LAN or you need a dedicated link to one workstation.
Static IPv4 on the PC is mandatory
Set the PC before you rely on the link. Wrong subnet is the usual reason the Web Interface does not open.
Step 1 - Set the PC to 192.168.1.51
Set these IPv4 values on the computer
| Field | Value |
|---|---|
| IP address | 192.168.1.51 |
| Subnet mask | 255.255.255.0 |
| Gateway / router | Leave empty or use 192.168.1.50 (printer default in this mode) |
The printer uses 192.168.1.50 on the cable; the PC must stay on the same 192.168.1.* network.
Same /24 on both ends
The PC must stay on 192.168.1.* with the printer - not 192.168.0.*, 10.*, or another LAN. Only the last octet may differ from 192.168.1.50.
| Step | Action |
|---|---|
| 1 | Open Settings > Network & Internet > Ethernet. |
| 2 | Select your Ethernet adapter. |
| 3 | Next to IP assignment, choose Edit > Manual. |
| 4 | Turn IPv4 on. |
| 5 | IP address: 192.168.1.51 - Subnet mask: 255.255.255.0 - Gateway: leave empty or 192.168.1.50. |
| 6 | Save. |
| Step | Action |
|---|---|
| 1 | Open System Settings > Network. |
| 2 | Select Ethernet > Details. |
| 3 | Open the TCP/IP tab > Configure IPv4: Manually. |
| 4 | IP address: 192.168.1.51 - Subnet mask: 255.255.255.0 - Router: leave empty or 192.168.1.50. |
| 5 | OK, then Apply. |
| Step | Action |
|---|---|
| 1 | Open wired Ethernet connection settings (wording varies by distro). |
| 2 | Set method to Manual (or Static). |
| 3 | Address: 192.168.1.51 - Netmask: 255.255.255.0 - Gateway: empty or 192.168.1.50. |
| 4 | Save and apply the profile. |
No internet on that wired NIC
That adapter is on an isolated /24. Use WiFi or another NIC if you need the internet at the same time.
Step 2 - Cable and power sequence
Complete WiFi module removal. Power off the printer. Run one cable printer ? PC - not through a router.
Power on, wait 60 s for detection.
- Blue - Ethernet to PC succeeded.
- Red - fault; see Troubleshooting.
DHCP attempt first
Firmware still tries DHCP briefly; with no server it locks to 192.168.1.50 for the printer. Wait the full window.
Step 3 - Web Interface and save
On blue, the touchscreen shows Network Connected for 192.168.1.50. Open http://192.168.1.50 or http://22idex.local on the PC, confirm the Web Interface, then Save network configuration.
Cold boot test: White LEDs after 60 s mean the mode saved. If not, use Macros > System > Settings > Network > Enable Ethernet to PC Mode, reboot, recheck.
IP discovery
The printer writes 0:/IP_address.txt on the SD card (mode, IP, timestamp).
Web Interface - Console: send M552 I0. Response includes the current IPv4 for interface 0.
Without the UI: power off, remove the SD card, read IP_address.txt on a PC.
Hostname: Try http://22idex.local in a browser if multicast DNS is allowed on your network.
Static IP (no DHCP)
When DHCP is blocked but the printer already reaches the LAN once:
- Open the Web Interface.
Macros > System > Settings > Network > Assign Static IP.- Run the macro: detect link type, accept or type an address, test, save.
Persists across reboot
Saved static config survives power cycles; the printer stops depending on DHCP for that profile.
