VEMCO – VR100 Manual 28 May 2018 9
This hydrophone is also weighted for easier deployments. When a transponding hydrophone is attached to a
VR100-200, acoustic communication to a transponding receiver is possible.
All hydrophones listed in the table below will function with either VR100 model, although the transponding
capabilities of the VHTx hydrophone will only function with a VR100-200 running firmware version 3.3.1 or
later. The hydrophone you choose to use will depend on your needs.

Communicating with a receiver
(VR2Tx, VR2AR, HR2) to read health
and stats, or to activate an acoustic
release (VR2AR only).
Regardless of the hydrophone being used, it is connected to the VR100 through the bulkhead connector on the
side of the receiver (see section 2.1.1).
