# Sony RCP-TX7 Remote Control Panel
|
|
|
|
## Summary
|
|
|
|
The Sony RCP-TX7 is a larger remote control panel for Sony DXC-D30/D30P and
|
|
DXC-637 series camera systems. It can connect through CCU-TX7/TX7P systems, and
|
|
some later CCU-D50 workflows support it in TX7 mode.

## Service Manual Leads
|
|
|
|
The local manuals folder now includes a downloaded RCP-TX7 service manual:
|
|
|
|
- [docs/manuals/0a9f4a.pdf](manuals/0a9f4a.pdf) - ManualsLib-rendered
|
|
22-page service manual from manual 3317117.
|
|
|
|
ManualsLib also links that service manual as an "Also See" item from the
|
|
operating manual page:
|
|
|
|
<https://www.manualslib.com/manual/3317117/Sony-Rcp-Tx7.html>
|
|
|
|
Several manual sellers list `RCP-TX7 Volume 2` separately and describe it as a
|
|
schematic/circuit-diagram volume:
|
|
|
|
- <https://www.owner-manuals.com/RCPTX7VOLUME2-service-manual-SONY.html>
|
|
- <https://www.manuals-in-pdf.com/download-RCPTX7VOLUME2-SONY-p-1426169.html>
|
|
- <https://pdf-manuals.ru/sony/rcp_tx7_volume_2_manuals.html>
|
|
|
|
For board-level repair, Volume 2 is likely still important because it is
|
|
repeatedly described as containing circuit diagrams/schemas and parts catalog
|
|
data, and it is not present in the current local PDF set.
|
|
|
|
## Connector and Protocol Notes
|
|
|
|
The RCP-TX7 has a 10-pin CCU/camera connector. The operating manual states that
|
|
power supply and signal exchange are both carried through this connector.
|
|
|
|
The RCP-TX7 specification says data transfer uses a new protocol complying with
|
|
RS-232C. The DXC-D30 material similarly says the 10-pin remote connector for
|
|
RM-M7G/RCP-TX7 is designed according to RS-232C and can be controlled from a PC
|
|
with the proper Sony protocol.
|
|
|
|
Practical implication:
|
|
|
|
- Do not assume generic RS-232 command syntax.
|
|
- Verify voltage levels and pinout from service manuals before wiring adapters.
|
|
- Expect a proprietary Sony command protocol above the serial layer.
|
|
|
|
### 10-Pin Connector Pinout
|
|
|
|
The RCP-TX7 service manual and CCU-TX7 service manuals give enough information
|
|
to build a working restoration pinout. The RCP-TX7 connector is a 10-pin male
|
|
`REMOTE` / `CCU/camera` connector. Its mating connector is listed as Sony
|
|
`1-566-437-11` 10-pin female, equivalent to a Hirose `HR10A-10P-10S` assembly.
|
|
|
|
| Pin | Signal | Direction / purpose | Notes |
|
|
| ---: | --- | --- | --- |
|
|
| 1 | Spare | unused | No function shown. |
|
|
| 2 | VBS X | CCU/camera to RCP | Composite video, 1.0 Vp-p, sync negative. |
|
|
| 3 | VBS G | video ground | Ground/reference for pin 2. |
|
|
| 4 | S.DATA | RCP to CCU/camera | RS-232C-based serial data, 38,400 bps in CCU-D50/TX7 notes. |
|
|
| 5 | S.DATA GND | serial/data ground | One of two data grounds. |
|
|
| 6 | S.DATA GND | serial/data ground | Second data ground. |
|
|
| 7 | S.DATA | CCU/camera to RCP | RS-232C-based serial data, 38,400 bps in CCU-D50/TX7 notes. |
|
|
| 8 | Spare | unused | No function shown. |
|
|
| 9 | Power ground | DC return | Ground for the +12.5 V remote power feed. |
|
|
| 10 | Power input | DC input to RCP | Nominal +12.5 V DC; documented range 10.6 V to 17.0 V. |
|
|
|
|
The CCU-TX7 service manual describes the CCU-side direction as pin 4
|
|
`RCP -> CCU` and pin 7 `CCU -> RCP`. On the RCP service manual side, the same
|
|
two conductors are seen from the opposite end of the cable.
|
|
|
|
Pins 2 and 3 are composite video, not serial. Some CCU-TX7 notes say the remote
|
|
video output on those pins applies to later serial-number units only.
|
|
|
|
### Cable and Power Notes
|
|
|
|
- Intended cable family: CCA-7, with CCA-7-5 supplied in some RCP-TX7 systems.
|
|
- Maximum length: 50 m.
|
|
- RCP power is supplied through the connector, not by a local power supply.
|
|
- Operating manual power consumption is 4.0 W. Treat OCR readings of `40 W` as
|
|
a decimal-loss error unless confirmed from the original page image.
|
|
- Use shielded cable and preserve strain relief; the manuals explicitly call
|
|
for shielded interface cables and warn against tight bends behind the panel.
|
|
|
|
### Protocol Notes
|
|
|
|
The manuals repeatedly describe the link as RS-232C-compliant or based on
|
|
RS-232C, but Sony protocol is still required. The DXC-D30 manual says a PC can
|
|
control the camera through the 10-pin remote connector only with the proper Sony
|
|
protocol. For restoration, first verify power and continuity, then scope pins 4
|
|
and 7 with high impedance before attaching any serial adapter.
|
|
|
|
## Repair Notes
|
|
|
|
Good first checks for a non-working RCP-TX7:
|
|
|
|
- Confirm 10 V to 17 V supply on the 10-pin remote cable.
|
|
- Confirm polarity before applying power: pin 10 is positive and pin 9 is DC
|
|
return.
|
|
- Confirm pins 4 and 7 idle/transition as serial data before attempting to
|
|
decode commands.
|
|
- Inspect the circular 10-pin connector and cable.
|
|
- Confirm the CCU/camera is in a mode that accepts RCP-TX7 control.
|
|
- On CCU-D50, verify whether the system should be in `TX7 mode`, not `M5A mode`.
|
|
- On CCU-D50 in TX7 mode, verify the remote/local priority switch: remote
|
|
priority is needed for a device on the rear-panel REMOTE connector to take
|
|
control.
|
|
- On CCU-D50, set `RCP RATE` to `38400`; the manual says RCP-D50/D51/TX7 will
|
|
not connect with the wrong rate.
|
|
- Check operation lock mode; in `LOCK`, most controls are intentionally disabled.
|
|
- If using CCU-TX7 with COU-TX7 installed, confirm panel/remote/local control
|
|
selection.
