Glanded Cable Entry
Some sensors such as pressure sensors have a pressure equalization tube that must be vented into a dry
environment to prevent condensation damage via the vent line. The M12 connector can be replaced with a PG9
Gland that uses the same size hole and can provide a weatherproof cable entry into the Ai1 housing (illustrated in
Figure 12).
3.7
Braided Wrap
The Ai1 cable entry is shaded by the solar panel and mounting bracket,
minimizing UV damage. Braided wrap protects the cable from the underside of
the Ai1POLE to the entry into the SSPOST, to prevent UV damage, as illustrated in
Figure 12.

Must be used on C1/C2, with internal GPS connected to ComRS232 Rx which requires internal solder jumpers.

Only if ordered with analog output option, RS232 mode is default
10
The wiring inside the Ai1 uses a JST connector which has different colors. JST Red=M12 Brown, White = White, Green = Yellow, Black = Black and Grey = Orange.
