Sony RM-D800 9-pin jack pinout / standalone controller?

Just wondered if you know where I can find the pinout for the remote
connector on the back of my Sony RM-D800 ? (That's the remote controller
that works with PCM800, DA98 etc.).

I want to use it as a 9pin controller for a gig - however,
the D800 gets its power from whatever device you plug it into - so I'd have
to have an unused DA98 plugged in on the stage.

If I get the pinout I can rig a power supply to connect to it.

Hi, D-

Good to hear from you. It's been a while. I've assembled some info below. It should help. Please let me know if this works for you.

The original DA-88 remote by Tascam was the RC-848, which was replaced by the RC-898. The Sony model RM-D800 corresponds to the older RC-848.

What makes this explanation difficult is that only the 848 manual shows the pinout (p 63), and only the 898 manual explains what these jacks do.

The 848 had 4 connectors,
DA-88 sync (15-pin)
EXT 1 37-pin
EXT 2 15-pin
EXT 3 9-pin (RS-422)

So I assume you're inquiring about EXT 3 (9pin).

Here's the the pinout:
1 Shield
2 RX+
3 TX–
5 —
7 RX–
8 TX+
9 Shield

NEXT, for explanation, we turn to the 898 manual, which you can download here.

NOTE THAT THE 898 calls the 9-pin connector EXT 2, while the old 848 calls the 9-pin jack EXT 3!!! So bear that in mind when reading this:

The 898's .pdf manual has this to say (p 13 on and p 16 on):

[42] EXT 1 – parallel and GPI port
This port provides parallel control and tally signals
or GPI control for event control, which may
be triggered from a small “cue list” in the RC-898.
The pinout for this 15-pin ’D’-sub connector is
given in 3.2, “Connections (parallel units)”. You
will need to make your own cable, referring to the
the table above, and to the equivalent table in the
manual of the other equipment if you wish to control
an external unit through parallel control, or if
you wish to send GPI events from the RC-898.

[43] EXT 2 - serial port
This 9-pin ‘D’-sub connector is used for the con-trol
of devices implementing the Sony P2 proto-col.
A cable designed for P2 connections may be
used with this port.

[45] DIP switches (1 & 2)
The two DIP switches are both on when in the
down position. As shipped from the factory,
switch 1 is off (up) and switch 2 is on (dow), and
you probably will not need to change them.
However, when a passive device is connected to
the EXT 1 connector and power is not provided
from the device to the tally supply pin, this switch
1 (TALLY POWER) should be set to the on
(down) position, allowing the RC-898 to use its
own power for this purpose.
Switch 2, GND LIFT (ground lift) controls the
isolation of the ground of the RC-848/DTRS sys-tem
from the ground of devices attached to the
EXT 1 and EXT 2 ports. Usually this switch is in
the on (down) position, but you may need to turn it
off (up) if your system suffers from hum prob-lems.
However, a full discussion of ground loops
and their associated problems is outside the scope
of this manual, and we recommend that you con-sult
one of the many reference works on this sub-ject
if necessary.


3.2.1 Connections (GPI event units)
The EXT 1 parallel port may also be used for the
purpose of controlling up to five GPI event-con-trolled
The way in which these devices may be triggered
from the RC-898 is explained in 9.2, “Controlling
GPI devices”.

3.2.2 Parallel control/GPI pinout
The following table gives the pin assignments for
the parallel/GPI connector (EXT 1). GPI connections
are shown in square brackets:
1 STOP/[Event 1]
2 PLAY/[Event 2]
3 FF/[Event 3]
4 REW/[Event 4]
5 REC/[Event 5]
6 N/C
7 Common
8 Tally supply
9 PLAY tally
10 FF tally
11 REW tally
12 STOP tally
13 REC tally
14 REC COMMAND tally
15 GND

3.3 Connections (RS-422 units)
The RC-898 allows control of a unit implementing
the Sony P2 protocol. This connection is made
through the EXT 2 serial port [43], using a serial
cable designed for this purpose. The pinout for
this connector is as follows:

1 Shield
2 RX+
3 TX–
5 —
7 RX–
8 TX+
9 Shield

Make the connection using a cable designed for
RS-422 connection (check the pinout of your P2
device before making the connection). This
machine may now be controlled by the RC-898
when the E2 MACHINE indicator [8] is lit.


That should be it!! Good luck figuring it out!

As it turns out, the DA-88 sync (15-pin) is the one I need - it will tell me what the power requirements are for the remote - it won't work as a stand alone 9pin controller driving something through EXT3 - it has to be plugged into DA88 (or whatever) to get power - I want to just build an external PSU.

Thanks for the info - I'll keep you posted if I get it figured.

Did you figure out an external PSU for your DA-88 remote? Is there any info that might be useful to other DA-88 users?

Used a da88 as power supply! The rig was only standby and in the event was never used. However had I not brought it I’m sure we would have needed it.

Thanks again for your help in pulling that together.
