are keyed connections so they cannot be inserted incorrectly. Connect the unlabeled
COM cable to COM1 on the new SBC.

(o) If Field Modification FM13016 or FM13016A was previously applied to the transmitter, the
UB97 Reset Adapter Assy PWB (207-5760) can be disconnected from P33 or P35, then
P33 or P35 can be connected directly to A1U1RST_BTN1. Otherwise, connect P104 to
P33 (NX15/25/50 only) or P35 (for NX100) and P103 to A1U1RST_BTN1 on the SBC.
See Figure 11.
(p) Locate the multi-connector cable (Nautel Part # UA312) in the 207-5060-01 Cableset,
provided with the Field Modification kit. Mate the largest connector with J1 of the SSD
installed in step (m). Connect the other ends to the SATA1 and SATA_PWR1 connectors
on the SBC (see Figure 9).
