  • With the power disconnected, carefully plug the SPA100 into the target SIM ensuring the white indicators are aligned.
  • The SPA100 PCB Edge Connector is not polarized or keyed. Connecting it backwards may damage your SIM.
  • Unless the appropriate jumper on SPA100 is removed, the USB Mini-B power input pin on the SPA100 is directly connected to the SIM's USB Mini-B power input (if present): connecting both simultaneously may damage your SIM or even your PC/Hub powering the SIM/SPA100.
  • The PCB Edge Connector is not designed for live power insertion/removal. Ensure the power to the SIM is off when connecting or disconnecting from this port to avoid damage your SIM or connected equipment.
  • When connecting a SPA to a SIM, make absolutely sure you do not get the two reversed/upside down. They are not keyed/polarized and connecting the SPA backwards can damage your SIM, SPA, or USB hub. Here's an example of the SPA100 plugged into a SIM:
  • Look for the white silk screen "spikes" and make sure they're aligned. To avoid damage to your SIM, SPA, JTAG debugger, or USB host/hub, do not plug/unplug a SPA with power applied to the system.
