SendPro+ Connection Support

How do I fix a wired network connection problem on the SendPro+?

Wired connection problems (or “Unable to resolve host” / “Failed to Update” messages) are usually caused by settings, the physical connection or a firewall. Work through these solutions.

Solution 1 — Restart the device

1. Unplug the power cord and the network cable (the screen turns off after 10 seconds).
2. Wait two minutes, then plug the power cord directly into a wall outlet and power on.
3. Once on, reconnect the network cable, wait one minute and try again.

Solution 2 — Check the physical connection

Make sure the device is not connected to a phone line or a PC (PC Meter Connect is not supported), and the network cable is securely clicked in. Check the LED lights where the cable plugs in: if off, try the other end in an active router/jack or a different cable; if the green and amber LEDs flicker, the connection is active — go to Solution 3.

Solution 3 — Check the network settings

In Settings > Wired (Ethernet), select DHCP to get an IP automatically, or Static IP and enter the IP address, Netmask, Gateway and DNS Address from your IT department. Set a proxy via Proxy setting if required.

Solution 4 — Check for firewall issues

Your firewall may be blocking required ports or addresses — see the networking details below and contact your IT department. If a wired connection still fails, try Wi-Fi instead.

How do I fix a wireless (Wi-Fi) connection problem on the SendPro+?

Wi-Fi problems are usually caused by settings, signal strength or a firewall.

Solution 1 — Restart

Unplug the power cable, wait 2 minutes, plug it directly into a wall outlet and power on.

Solution 2 — Signal strength

Check the Wi-Fi gauge — below two bars, performance may be intermittent. Move the machine and access point closer, remove sources of interference (microwaves, cordless phones), or select another internal Wi-Fi network.

Solution 3 — Network settings

1. Turn Wi-Fi off in Settings > Wi-Fi, restart, then turn Wi-Fi back on.
2. Select your network and tap Forget, then re-enter the password and tap Connect.
3. For EAP method, proxy or static IP, tap Advanced Options.

If Wi-Fi still fails, check the firewall (see networking details below) or try a wired connection.

How do I set up a Wi-Fi connection on the SendPro+?

1. Tap the Settings (gear) icon, then Wi-Fi in the Device & Network section.
2. Choose your network (or tap Add Network for a hidden one).
3. Enter your Wi-Fi password (use show password to check it).
4. For a proxy or static IP, tap Advanced Options and enter the values from your IT department.

Tip: If the machine will not connect, test the Wi-Fi and password on a phone or laptop. For authentication errors or unknown settings, check with your IT department.

How do I set up a wired connection on the SendPro+?

In Settings > Wired, check whether the connection type is DHCP or Static.

For DHCP: select DHCP and tap Connect. If it fails, unplug the power, wait 2 minutes, reconnect to a wall outlet, power on, and reconnect via DHCP.

For Static: get the IP Address, Netmask, Gateway and DNS Address from your IT department, enter them and tap Connect. If it fails, remove the network cable, tap Connect and let it fail, reconnect the cable, re-enter the values and tap Connect.

How do I set up a proxy server on the SendPro+?

A proxy server acts as a gateway between your network and the internet. To set one up, open Wi-Fi or Wired in Settings and set the proxy to Manual.

1. Tap Settings, then Wi-Fi or Wired (Ethernet).
2. For Wi-Fi, select the network, tick Advanced Options and set Proxy to Manual; for Wired, set the Proxy Setting to Manual.
3. Enter the Proxy Hostname (IP/HTTP/HTTPS address) and Proxy Port.
4. (Optional) Use Bypass for internal URLs, and tick Need Authentication to enter a proxy username and password (case-sensitive).

How do I forget a Wi-Fi network on the SendPro+?

Forget a network if you do not want the device to auto-connect, or to resolve a Wi-Fi issue.

How do I check my network connection on the SendPro+?

Tap the Check Network application icon in the application drawer at the bottom of the Home screen to confirm the machine can reach the services it needs for rate updates, transaction sync and postage refills.

How do I fix connection error codes (1811, 1814, 1815, 1816, 1822, 1825, 1826, 1829, 1870, 51, 23, 200D) on the SendPro+?

These codes (and messages such as “Unable to Resolve Host”, “PB Commerce Cloud Not Found” or “Sync your data”) mean the machine is not connecting to the Data Centre. To resolve them, sync the data and restart, then troubleshoot your connection type.

1. Tap the Settings (gear) icon and tap Sync Transaction Data.
2. Restart: unplug the power cable, wait for the display to turn off, wait one minute, then plug directly into a wall outlet.
3. If it still fails, follow the wired or wireless troubleshooting above for your connection method.

How do postal rate and software updates work on the SendPro+?

The machine updates rates and software automatically overnight — keep it on and connected. To update manually, tap Rates and Updates at the bottom of the Home screen; for software, swipe up to the second row of buttons. If an update is available, a progress bar shows the download and installation.

How do I fix a “PB Commerce Cloud Not Found” message on the SendPro+?

This message means the device cannot sync its daily transaction data, usually due to a network, physical connection or firewall issue. Restarting is the most common fix.

On Wi-Fi: in Settings > Wi-Fi, Forget your network, slide Wi-Fi off, unplug the power for 10 seconds, power back on, then turn Wi-Fi on, select your network, enter the password and Connect. Only do this if you know your Wi-Fi password; for Static IP, contact IT.

On a wired connection: in Settings > Wired, check whether you use DHCP or Static IP. For DHCP, select it and Connect; if it fails, power-cycle with the cables out for 2 minutes and reconnect. For Static IP, note the IP Address, Netmask, Gateway and DNS Address, then reconnect and re-enter those values.

Note: If you still cannot connect, ask your IT department to verify the network settings against the networking details below.

What are the networking and connectivity details for the SendPro+?

If you have strict network security, your IT team may need these specifications. All communication is initiated by the device over ports 80 (HTTP) and 443 (TLS), with port 53 for DNS. The following URLs must be reachable without SSL inspection or web filtering.

Required URLs include:

• Distributor: distservp1.pb.com (ports 80 and 443)
• Funds: decometlb20.pb.com, ukcometlb12k.pb.com, decometlb5.pb.com, swcometlb2.pb.com, cometservp1.pb.com (port 443)
• Rates & Updates / Downloads: dlsdlp1.pb.com, pbdlsp1.pb.com (and variants), pb-ota.redbend.com (port 443)
• Manage Accounts: ms1app.pb.com (port 443)
• Health data: s3.amazonaws.com (port 443)
• Connectivity test: connectivitycheck.gstatic.com and Google DNS 8.8.8.8 (port 53)
• PB Web Services: api.pitneybowes.com, api.precisely.com, pitneybowes.okta.com (port 443)
• Parcel Shipping: sending.us.pitneybowes.com and sendpro.pitneybowes.com domains (port 443)

Ports: Port 80 (HTTP — web services, TeamViewer), Port 443 (TLS — PSD refills/audits, transaction uploads, OS/software/rates updates), Port 53 (DNS — allow both UDP and TCP).

Advanced requirements: the device supports 802.11n Wi-Fi with WPA, WPA-2 PSK and WPA-802.1x (LEAP) on 2.4 and 5 GHz (WEP is not supported). A minimum of 384 kbps up/down is required (1 Mbit/sec recommended). The internal base and tablet use the 192.168.10.240–255 and 192.168.10.96–111 subnet ranges, so the network gateway must not use those addresses. Remote support uses TeamViewer over port 5938.

Note: There is also a recommended list of Google, AWS and device-management domains that should remain open. If your IT team needs the full URL and port list, contact us and we will provide it.
