Serial Connector Pinout

The physical connector is an RJ-25 (6P6C) on the Trav’ler or RJ-12 (6P6C) on the G2 — same form factor, same 6-pin modular jack.

Adapter Chain by Variant

Variant	Adapter	Wires Used

Carryout G2 (Davidson)	USB -> RS422 (5V TTL)	Pins 2-5 (full-duplex)
Carryout G2 (confirmed)	DSD TECH SH-U11 USB -> RS422 (FTDI FT232R)	Pins 1-5 (full-duplex + GND)
Carryout G2 (ESP32)	ESP32 UART2 -> RS422 module (DIYables)	Pins 2-5 (full-duplex)

Power

120VAC input to RP-SK87 power supply, outputs 12VDC to IDU. Internal coax carries 12-18VDC bias for the LNB.

Physical Setup

Base marked with arrows and “BACK” at 0/360 deg (North)
Align “BACK” with true North for accurate tracking
Gpredict rotor config: 127.0.0.1:4533, 0->180->360 mode, min EL 15, max EL 90
No obstructions taller than 8” within 32.5” of base center

Calibration

On power-up, the dish performs calibration movements to establish position and cable wrap limits (~10-15 minutes on Carryout, shorter on Trav’ler). After calibration, firmware automatically starts a TV satellite search — the init sequence kills this.

The Carryout uses motor stalling (not limit switches) to detect mechanical boundaries. Expect audible grinding during calibration.

EL recalibration (via IDU buttons): POWER -> ENTER (hold 2s) -> User Menu -> INSTALLATION -> Calibrate EL -> confirm hard stop position.
