3 New features in ACD301RF MKIII
3.1 CLOCKIT Radio Slate
The CLOCKIT Radio Slate is a combination of a small UHF telemetry
transceiver powered by 2 AA batteries and a receiver built into the master
slate. This makes the unit more compact than external receivers and easier
to use. The range can be up to 200 meters but in difficult conditions it is
typically 50 meters.
3.1.1 Transceiver unit TC-TRX
The transceiver unit shipped with the ACD301RF can be configured to
transmitter or receiver by sliding switch inside the battery compartment.
A dual color LED indicates transmit (green) or receive (red).
When shipped, it is set to transmitter.
The transceiver has a LEMO 5-pin connector:
pin 1 = ground,
pin 2 = tc-in,
pin 5 = tc out.
Mating connector is LEMO part no. FGG.0B.305.CLADxxZN or the shorter
version JGG.0B.305.CLADxxZN.
Also on the top is the on/off switch and the antenna.
The transceiver is shipped with our TC-IN cable XLR-3F to LEMO-5pin to
feed time code into the transceiver. This cable can also be used to feed time
code into the slate by wire.
The TC-TRX is available in 315 MHz (green marked antenna), 418 MHz (blue
marked antenna) and 433 MHz (red marked antenna).
Note: the TC-TRX uses “amplitude manipulation” and is not compatible with older
slates or the TC-TX / TC-RX, a.k.a. “Black Box”.
3.1.2 Built-in TC-TRX
A transceiver is built into the slate and can be turned on and off with the
4-DIP-switch
switch 1
up = off, down = on
When the slate is in GEN mode, the TRX is set to transmitter. With 4-DIP-
switch
switch 2 user can select if time code is transmitted continuously
or as a five seconds burst after clapping the slate.
up = cont., down = burst
When the slate is in READ or READ/GEN mode, the TRX is set to receiver.
Always set the TC-TRX to the right mode.
Note: With the receiver on and the transmitter off there will be noise in the
time code input line making the led glow red (see 1.1.3). Always switch off
the transceiver when not in use.
Note: Some Steadycam and camera focus remotes use the same frequency
as our transceiver module, leading to poor reception and low range
(interference).
