Of the legacy models, only a limited supply of refurbished Tablo DUAL LITE Over-the-Air [OTA] DVRs remains for sale.
There are a couple of different ways you can tell which Tablo unit you have:
Table of Contents
By the Way the Unit Looks
4th Generation Tablo

Tablo DUAL LITE or Tablo DUAL 64GB or Tablo DUAL 128GB

These models are square with rounded corners, air vents on the slightly domed top, with a shiny half-moon section (the IR remote sensor) and a Tablo logo screen printed on the front. They come with a Tablo-branded remote.
Original Tablo 2-Tuner and 4-Tuner
These models are rectangular in shape with a flat top with no air vents. The Tablo logo is screen-printed on the front.
Using the Serial Number
You can identify which Tablo you have by the first three letters of the serial number. The serial number can be located on the very bottom of your Tablo unit, as well as the box the Tablo came in.
If the first three letters begin with:
| GI-C | This is a DUAL LITE or DUAL 128GB unit. |
| GI-Q | This is a QUAD or QUAD 1TB unit. |
| HD-A | This is a DUAL HDMI unit. |
| HQ-A | This is a QUAD HDMI unit. |
| LD-B | This is a 2-Tuner, 4-Tuner or DUAL 64GB unit |
4th Generation Tablo models do not have serial numbers with letter prefixes. They only have MAC addresses.
Using the Ports on the Back of the Unit
The ports on the back of your Tablo will help determine if you have a 4th Generation Tablo, a TV-connected Tablo, or a network-connected Tablo. It can also help you identify if your network-connected Tablo is a DUAL or QUAD.
4th Generation Tablo
The 4th generation Tablo is like legacy network-connected units and will only have ports for the antenna, USB, Ethernet and the power supply. The order of the ports is reversed from legacy model Tablo devices and the Ethernet port does not have LEDs.

The Tablo DUAL LITE and Tablo DUAL 128GB are network-connected units and will only have ports for the antenna, USB, Ethernet and power supply.
Tablo QUAD or TABLO QUAD 1TB
The Tablo QUAD and Tablo QUAD 1TB are network-connected units and will have ports for the antenna, USB, Ethernet and power as well as a SATA compartment for an internal hard drive.
