2 Applications Affected
This Errata affects applications requiring use of the UART CTS hardware flow control output
from the Skywire modem. The UART CTS signal (Pin 12 on the Skywire interface) is not
connected on NimbeLink PCBs prior to PCB revision F. This Errata does not affect your
design if any of the following are true:
1) Skywire PCB is revision F or higher
2) USB is used for communication instead of UART
3) Hardware design does not connect to Skywire CTS pin
4) Design does not implement hardware flow control in hardware and/or software
5) Software design implements software flow control (XON/XOFF)
3 How to Identify PCB Revision
The PCB revision is found on the bottom side of the modem between J1 (Skywire interface
connector) and J3 (Micro-SIM socket). The revision is written in white silkscreen and is of the
form 20001 rev X.

4 Workarounds
For customers that have affected product, these alternatives may permanently alleviate the
effects of the Errata in your application.
1) Use USB interface instead of UART
2) Use software flow control (XON/XOFF) instead of hardware flow control
3) Modify existing modem to correct for CTS Errata (see section 5)
5 Board Rework
The Errata can be repaired on affected product by soldering a wire to the underside of the
modem. The wire must connect Skywire interface pin 12 to U2 pin 18. Adding this wire will
not invalidate the product warranty, however, poor workmanship can damage the modem and
invalidate the warranty.
