8.1 TAPE MACHINE REMOTE CONTROL PANELS
There are two tape machine remote control panels available for use in the BMX III mainframe—one for
cart recorders (PR&E #99-240) and one for cassette and reel-to-reel tape recorders (PR&E #99-221). Both
consist of five momentary-action switches, and both are mounted in the lower module area of the mainframe
in the positions labeled A through E, as shown in Figure 2.3. These positions are pre-wired with 24-pin
logic cables, which are routed to OPTION A - E positions on the rear of the mainframe, as shown in Figure
2.5.
Tape machine remote control panels operate in conjunction with input module remote controls, and
connection to cart and tape recorders is accomplished by means of a "Y" cable located at the recorder, as
shown in Figure 8.5. Prefabricated remote control "Y" cables for most commercial cart and tape machines
are available from PR&E.
8.1.1 Cart Recorder Remote Control Panel
The cart recorder remote control panel (PR&E #99-240) can control the record, tertiary cue tone, secondary
cue tone, play and stop functions of a connected cart recorder. For a schematic showing rear panel Molex
connector pin assignment, and an illustration of the panel controls, see Section 8.6.
Presently, there are four different versions of this panel available from PR&E: #99-240-0, for use with cart
machines with no lamp tallies; #99-240-1, for use with cart machines with 5 volt lamp tallies; #99-240-2,
for use with cart machines with 14 volt lamp tallies; and #99-240-3 for use with cart machines with 28 volt
lamp tallies.
8.1.2 Cassette And Tape Recorder Remote Control Panel
The cassette and reel-to-reel tape recorder remote control panel (PR&E #99-221) can control the record,
forward, rewind, play and stop functions of a connected cassette or tape recorder. For a schematic showing
rear panel Molex connector pin assignment, and an illustration of panel controls, see Section 8.6.
Presently, there are five different versions of this panel available from PR&E: #99-221-0, for use with tape
machines with no lamp tallies; #99-221-1, for use with tape machines with 5 volt lamp tallies; #99-221-
2, for use with tape machines with 14 volt lamp tallies; #99-221-3, for use with tape machines with 28 volt
