CONNECTING THE RMD TO THE M20 SYSTEM

POWER

The RMD works with any AC voltage from 90 to 250 volts, 50 to 60 Hz. This eliminates the

need for transformers or voltage switches. The RMD ships with an IEC-spec power cord

for the country to which the RMD was shipped.

The RMD’s IEC-spec AC cord is designed for connection to an outlet that

includes three pins, with the third pin connected to ground. Do not

substitute a non-grounded AC cord or lift the ground.

The ground connection is an important safety feature designed to keep the chasis of

electronic devices such as the M20, CADI remote, or RMD at ground potential.

Unfortunately, the presence of a third ground pin does not always indicate that an outlet is

properly grounded. Use an AC line tester to determine this. If the outlet is not grounded,

consult with a licensed electrician. When the AC current is suspected of having unstable

voltage and/or frequency, a professional power conditioner should be used.

The RMD is supplied with a standard detachable power cord. If the AC cable is too long or

short for the installation, you may substitute a UL-approved power cable of the proper

length, available in many electronics or computer stores (type “NEMA to CEE”).

CONNECTION TO M20(S) AND CADI AUTOLOCATOR

The RMD comes with one 25-foot long RJ-45 category 5 terminated (control) cable for

connection to one M20. If installation requires a longer cable (or more cables), use high-

quality category 5 spec’ed cable. Exceptional cable lengths of 1000 feet or more can be

used, depending on the quality of the cable.

The RMD may be connected to up to four M20s. If an RMD is to be used in conjunction

with an M20 and the CADI autolocator/remote control, an RJ-45 connector labeled “CADI”

is provided on the back panel of the RMD for connecting the CADI remote (see figure 1).

To connect the RMD to a four-M20 system:

1. Connect one end of a control cable to the REMOTE connector on the first M20 (tracks 1-

8), and connect the other end to the MACHINE 1 connector on the RMD.

2. Connect one end of a control cable to the REMOTE connector on the second M20

(tracks 9-16), and connect the other end to the MACHINE 2 connector on the RMD.

3. Connect one end of a control cable to the REMOTE connector on the third M20 (tracks

17-24), and connect the other end to the MACHINE 3 connector on the RMD.

4. Connect one end of a control cable to the REMOTE connector on the fourth M20 (tracks

25-32), and connect the other end to the MACHINE 4 connector on the RMD.
