 ### Step 9: Settings required for PURE Array serial connections
 
-For configuring PURE Array serial connections, use the following commands:
+Pure Storage arrays purchased prior to 2024 have revision R3 controllers which use rollover console cables and require the custom serial port connection commands below:
 
+**Pure Stoarge R3 Controllers:**
 ```bash
 ogcli update port ports-<PORT_#> 'baudrate="115200"' <PORT_#> Pure Storage Controller console
 ogcli update port ports-<PORT_#> 'pinout="X1"' <PORT_#>	Pure Storage Controller console
 ```
 
+Newer Pure Storage appliances, and systems upgraded from R3 to R4 Pure Storage controllers, will use straight-through console cables with the updated settings below:
+
+**Pure Storage R4 Controllers:**
+```bash
+ogcli update port ports-<PORT_#> 'baudrate="115200"' <PORT_#> Pure Storage Controller console
+ogcli update port ports-<PORT_#> 'pinout="X2"' <PORT_#>	Pure Storage Controller console
+```
+
 **Parameters:**
 
 | Parameter Name  | Description                 |
 | ----------------| --------------------------- |
 | PORT_#          | Terminal Server port number |
 
-These commands set the baudrate and pinout for connecting to the Pure Storage Controller console.
+These commands set the baud rate and pinout for connecting to the Pure Storage Controller console.
