4. Click on the MRX-1 in the Model Designer window.
5. Click on the "Properties" tab at the lower right side of CCP
6. Click on RS-232 Port #1 on the actual MRX-1 image.
7. The Port 1 RS-232 Properties appear in the Properties tab.
8. Set the Baud Rate, Data, Parity and Stop Bits for the connected
RS-232 component. (The manufacturer of the RS-232 component
will provide the correct values.)
9. Click on RS-232 Port 2 and repeat the process if it will be con-
trolling a component RS-232.
Relay
When connecting the MRX-1 Relay, the controlled device end may
be terminated with a plug or connected to wire terminals. In either
case, the connections to the MRX-1 Relays are the same for a given
switch closure configuration. Discrete commands for open and
close are programmable for three modes of operation: Latching,
where the relay stays closed until told to open, (or stays open until
told to close), Timed Momentary, where the relay can be set to stay
open or closed for a specific duration, or Momentary, where the
relay stays open or closed for as long as the remote button is
pressed and held. DURATION (TIMED MOMENTARY): .1 – 99.9
seconds. RATING: 30V;.5A
NO (Normally Open)
1. For a device that PROVIDES VOLTAGE for use with a switch clo-
sure:
a. Connect the +V Terminal on the controlled device to the Relay
NO terminal on the MRX-1 rear panel, using one of the
included three -pin plug-in connectors.
b. Connect the Ground Terminal on the controlled device to the
Relay COM Terminal using the same plug-in connector.
2. For a device that REQUIRES EXTERNAL CONTROL VOLTAGE:
a. Splice the ends of a 12 volt wall adapter and connect it to the
Relay COM Terminal.
b. Connect the Relay NO Terminal to the +V Terminal on the
controlled device.
c. Connect the GND terminal on the controlled device to the
GND terminal on the MRX-1 rear panel.
When a properly programmed MRX-1 compatible remote sends an
ON command, (latching, momentary or timed) RELAY will close
and the controlled device will respond (turn ON an amplifier or
powered sub, raise a lift, drop a screen, open or close drapes etc.).
When the OFF command (latching, press and hold or time) is sent,
RELAY will OPEN and the controlled device will respond (reverse
previously switched mode). WIRE GAUGE: 24-14 AWG two-con-
ductor stranded; MAX LOAD: 30V; .5A.
