1. Introduction
1.1 Overview
NimbeLink's S2C (serial-to-cellular) Link Accessory Kit consists of simple, user
assembled device allowing easy access to the serial ports for both the USB and
RS232 interfaces on the Skywire® modem. The Kit is compatible with any of the
wide range of cellular technologies and carrier certified modems in the Skywire
cellular modem family.
The S2C Link Accessory kit is tough, compact, and is able to handle extremes of
temperature. The kit offers a range of powering and mounting options and draw
relatively little power, which suits them for remote applications like kiosks, digital
signage, control panels, security panels, and surveillance equipment. Their
ruggedness, simplicity, and low cost make them ideal for large volume, low-touch
applications.

3.3.1 Power Considerations
NimbeLink recommends having control over the power jack in order to reset the
Skywire if necessary
3.4 SIM Socket
The SIM card socket accepts Micro-SIM size 3FF SIM cards.
The SIM card socket is present on all LTE and GSM Skywire modems. The SIM
card socket is not present on the 2G 1XRTT nor 3G EVDO CDMA Skywire
modems.
3.5 RF Connectors
The S2C Link provides a primary and diversity antenna connection points. The
connectors are both standard SMA connectors, center pin: female. The primary
antenna connection must be used in all implementations. The diversity antenna
connection is not connected when used with a 2G 1xRTT, 2G GSM, 3G HSPA
Skywire.

3.6 Indicator LEDs
The S2C Link Accessory Kit has two external LED indicators. The POWER LED,
on the left of the enclosure, is illuminated when power is applied to the device.
The STATUS LED, on the right side of the enclosure, is a flexible use LED that is
often used as a status indicator by the Skywire modem to indicate the current
operating mode of the Skywire. It is driven by pin 13 from the Skywire and can
also be manually configured by sending AT commands to the modem. Please
refer to the user manual and AT command manual for the specific modem being
used.
