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 - 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 Was 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, notM5A 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 RATEto38400; 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.
