INSTALLATION & OPERATION
SIMULCOM - WHAT WHY and HOW (continued) 6.12
TO OPERATE AND/OR CHECK-OUT SIMULCOM
1. Attach hat to umbilical.
2. Attach comm-cable to AMCOM III, Diver 1 microphone and earphone.
3. Don hat and talk to yourself; if you hear your voice over the earphones the system is
working.
TO RECAP - We now have a system where diver 1’s microphone is connected to the Diver 1
microphone input of the AMCOM III and Diver 1’s earphone is connected to the earphone for Diver
1. All features such as diver push to talk switch and independent volume controls of the AMCOM
III remain intact. Tender uses a headset, which is plugged into the tender microphone and headset
jacks.
With the AMCOM III system you can mix 2-wire/simulcom systems, for example, Diver 1 and 2
could be simulcom while Tender can be 2-wire (no headset - use speaker for tender). Or, one
diver can be 2-wire and one can be simulcom. Just remember if any one person is on two-wire you
must use the push to talk (PTT) for that diver to hear or for the tender to talk.
Note: the PTT switch overrides diver conversations, (see operating guide for details).
Other configurations, which can be implemented with simulcom systems:
1. Remote station for equipment operator, or second tender on 2-wire or Simulcom.
2. Several remote stations with any combination of 2-wire or Simulcom.
