The RM-M7G and RCP-TX7 are best understood as part of a Sony SD camera remote control ecosystem. Related camera control units and cables often contain the pinout, mode, and compatibility details missing from the remote-panel manuals.
CCA-7 Remote Cable
The CCA-7 family is the 10-pin remote cable used by the RM-M7G and RCP-TX7.
Known cable lengths:
- CCA-7-5.
- CCA-7-25.
- CCA-7-50.
- CCA-7-100.
Sony Japan CCA-7-25 page: https://www.sony.jp/pro/products/CCA-7-25/feature_1.html
Important details from Sony Japan:
- Connects professional video cameras/camcorders and remote controls.
- 10-pin female to 10-pin male.
- Listed compatibility:
- DXC-D30/D35/327/537/637 series, CA-325 series, CCU-M5/M7 to RM-M7G.
- DXC-D30/D35/D50/D55 series to RCP-TX7/RCP-D50/RCP-D55.
The CCU-TX7 service manual includes a CCA-7 cable wiring diagram. Use that as the better source for cable fabrication or continuity checks.
CCU-TX7 / CCU-TX7P
Primary service manual: https://www.manualslib.com/manual/1068508/Sony-Ccu-Tx7.html
The CCU-TX7 is directly relevant to RCP-TX7 because the RCP was designed for CCU-TX7/TX7P camera systems with CA-TX7/TX7P camera adaptors.
Useful sections in the CCU-TX7 service manual:
- Connector input/output signals.
- REMOTE connector information.
- Connection connector list.
- CCA-7 cable wiring diagram.
- Board switch functions.
- Service information and disassembly.
- Video signal system adjustment.
- Triax interface system adjustment.
- Intercom/tally details.
The CCU-TX7 rear panel REMOTE connector is described as a 10-pin connector for the RCP-TX7 via a CCA-7 cable.
CCU-D50 / CCU-D50P
Official operation manual: https://pro.sony/s3/cms-static-content/operation-manual/3620534151.pdf
Sony Japan product page: https://www.sony.jp/pro/products/CCU-D50/
The CCU-D50 is useful because it bridges older RM-M7G-style operation and RCP-TX7-style operation:
M5A modesupports basic control using RM-M7G.TX7 modesupports more detailed camera operation using RCP-TX7.
The official CCU-D50 manual lists RCP-D50/D51, RCP-TX7, and RM-M7G as remote control options. It also includes a section on using the RM-M7G remote control unit and describes panel active handoff behavior.
The Japanese CCU-D50/CA-D50 catalog notes:
- CCU-D50 can use RM-M7G in M5A mode for basic DXC/DSR control.
- CCU-D50 can use RCP-TX7 in TX7 mode for broader picture-making controls.
- RCP-TX7 connector is circular 10-pin.
- RCP-TX7 power is DC 12 V, 10 V to 17 V range.
- RCP-TX7 power consumption is 4.0 W.
DXC-D30 / DXC-D30WS

This is useful for protocol research because it explicitly says the 10-pin remote connector for RM-M7G and RCP-TX7 is designed according to RS-232C, and that external PC control is possible with the proper Sony protocol.
System diagrams show:
- RM-M7G connected through CCA-7.
- RCP-TX7 connected through CCA-7.
- CCU-M7 / CCU-M5 camera control units.
- CCU-TX7 / CA-TX7 triax system.
