OPERATING PROCEDURES
DIVER COMMUNICATIONS 8.5
The AMCOM SERIES II can be operated in two basic modes of operation. The conventional
method of operation is known as 2-wire, this allows the diver to be heard by the tender, but
requires the operator/tender to actuate the Push-To-Talk switch in order to talk to the diver. The
modern method of operation allows two way conversations to be carried on simultaneously. Amron
calls this method of operation “SIMULCOM”. The diver and tender can talk to each other as you
would on a telephone. The same applies to diver to diver conversations. Amron tries to encourage
the use of SIMULCOM for superior communications and safety.
The Model 2825A-8225 has the capability of 2-wire and/or Simulcom (4 wire) communication
modes. Simulcom and 2-wire can be used simultaneously (mixed), divers on Simulcom, tender on
2-wire.
2-Wire communication is defined as a single communication path, the diver is the priority signal
path, tender listens to diver. Signal reversing is accomplished by pushing the Push-To-Talk switch;
diver hears tender. Often times a 4-conductor (4 wires) common cable is used with 2 wires tied
together as a pair (This is done for redundancy.), however this is still a 2-wire system.
Simulcom communication is defined as a dual communication path; a signal path (a pair of wires)
for up-link and a signal path (a pair of wires) for down link. A common example of Simulcom like
communication is the telephone. This permits the freedom of natural communication, lower system
noise, and diver to diver communication without having to attempt Crosstalk switching.
For an in depth discussion on Simulcom refer to SIMULCOM, WHAT, WHY, AND HOW!, located
at the end of the operation section of this manual.
