INSTALLATION INSTRUCTIONS, CONTINUED
COMMUNICATIONS ADJUSTMENT, Continued
is first indicated.
TYPE B--For wire-line telemetry, adjust telemetry input as in Type A above.
For FM subcarrier monitor, seA receiver, or TSL receiver, adjust input to 600 ohm
terluinals of remote control studio unit to .25-1.00 VAC RMS.
Adjust telemetry
io-
put as
~o
Type A above.
TYPE C--From the AM Modulation Monitor or high quality AM Receiver feed the
composite audio signal at 0 DBM level into the 600 ohm terminals of the studio
unit.
Adjust studio unit, RMC-l5S, input to middle of "SBT" range.
Indicator
should show "LO"if channel zero a
selected'.
Display should update every
4.8
seconds.
Over-modulation of
AM
transmitter may cause garbled data.
If numbers are
sent while meter
~s
ranglng, the operater
.
may also see wrong
figures.
Wait several
seconds with each reading to see that the meter has stabilized.
GENERAL COMMENT ON COMMUNICATIONS
Non existant, poor, or marginal communications links will prevent the remote
control from operating.
Additional testing of the links
to aSSure that they are
intact and of adequate quality may prove necessary to preclude a communications
problem.
Good engineering pract1ces including proper grounding, use of shielded
cables, labeling of wires which might be disconnected and routine inspection of
connections will solve a host of problems.
INSTALLATION OF RY 15 RELAY INTERFACE UNIT
The Ry 15 should be connected to the RMC-lST with the ribbon cable provided.
Either PI or P2 on the rear of the RMC-15T may be used since these contacts are in
para He
1.
The RY 15 Relay Interface Unit is used to physically output channel selection
through dry concacts, output raise/lower functions, and serve as an input port for
data samples.
The contacts for each of these operations are made through l6
p~n
blue-ribbon connnectors excpet for channel zero which uses a terminal strip.
Th~
channels are grouped three to a connector, l-2-3, 4-5-6, 7-8-9, 10-11-12, 1}-14-15,
