REAR PANEL DESCRIPTION
햲
Remote POWER
jack is for connection to a Rane RS 1 or compatible power supply. Units with outboard power supplies do
not
ground the chassis through the line cord. Make sure that these units are grounded either to another chassis which is earth
grounded, or directly to the grounding screw on an AC outlet cover by means of a wire connected to a screw on the chassis
with a star washer to guarantee proper contact.

for both audio Channels. This may be useful in case of computer failure and
dupli-
cates the function of the number ‘1’ Memory Recall Port switch
—without the need for an external switch.
햴
MEMORY RECALL PORT (MRP)
provides the ability to recall Memories using contact closures. See below.
햵
RW 232 INPUT
connects to the computer, or to the RW 232 OUTPUT of other RW 232 units.
햶
RW 232 OUTPUT
connects to the RW 232 INPUT on other units.
햷
RW 232 DEVICE ADDRESS
identifies each unit uniquely by assigning it
a number from 1 to 250. Refer to the Device Address Table on the follow-
ing page.
햸
Channels 1 & 2 Audio INPUT & OUTPUT
are balanced with chassis
ground. See RPE 228d CONNECTION, previous page.
MEMORY RECALL PORT
The MEMORY RECALL PORT (MRP) provides contact
closure control to recall any of the 16 system Memories for
both audio channels. Eight of the Memories are recalled with
simple switch closure to a single terminal (see the Normal
section of Table 1). There are nine screw terminals: one is
chassis ground, and the other eight are inputs which are
grounded to recall a preset Memory. Multiple units may be
controlled by connecting these terminals in parallel. Either
momentary or latching switches may be used. If a latching
switch is used, the selected Memory is recalled upon power-
up. If more than one terminal is grounded at a time, the
lower-numbered contacts will normally be ignored. A
“Binary” mode allows access to all Memories. No computer is
required after the initial setup.
The MRP may be completely reconfigured in RaneWare.
