Selection of the higher node address range should be done before the frame is installed. The process
involves:-
1.
Remove the frame from its packaging and put it on a suitable working surface.
2.
Remove the lid from the frame by unscrewing all the fixings with a cross-head screwdriver.
3.
The links that select the node address are on the board that runs past the fan at the rear of the
frame. They are labelled J1 and J2.
4.
The links are normally set in position 1, closer to the fan. This selects the lower address range. To
select the higher address range move both links J1 and J2 to position 3, further away from the fan,
this will produce the node address range 16 to 27.
5.
Replace the frame lid, making sure all the fixings are fully tightened to ensure continued EMC
compliance. Cards inserted into the frame will now have node addresses in the higher range.
6.
Replace the frame in its packing material to protect it until it is installed.
The cable required uses two 26 way high density D-type sockets. These should be connected with
screened twisted pair cable containing two pairs. All the wiring is pin to pin links. Pins 16 and 7
should use one twisted pair, pins 17 and 25 the other. The screen should be connected to pin 6 on both
connectors. To ensure continued EMC compliance only good quality screened cable should be used.
REMOTE CONTROL PANELS
Crystal Vision offers the choice of three remote control panels which can be used when a requirement
exists for panels and equipment to be located in different rooms.
REM1U
The REM1U is a 1U remote control panel. 482mm (19 inches ) and 85mm deep. The REM1U can be
powered by a mains adapter (supplied with REM1U) or via the dc power output on the FR2AV frame (
pin 15 of REMOTE 2). The mains adapter has a dc output voltage of +5.6Vdc which connects into a
3pin locking DIN connector on the rear of the REM1U. The REM1U can be powered from both at the
same time.
A multi-core cable from the REM1U (remote A connector) plugs into the FR2AV frame (REMOTE 2
connector)
.
If the REM1U is powered by the mains adapter , then the multi-core cable can be up
100m long ,however if the REM1U is powered only by the dc power output on pin 15 of REMOTE 2
connector then the cable is limited to 5m in length.

Note the transmit TX on one end of the cable connects to the receive RX on the other end.
For long cables (up to 100m long) use two twisted pairs with overall screen. On the 15way pins 1 & 2
are a twisted pair, and the pins 3 & 4 are the other twisted pair.
For shorter cables ( up to 5m long) use 6 core cable with overall screen. To ensure continued EMC
compliance only good quality screened cable should be used.
