Takahashi TRS02320: TEMMA/PC RS232 Cable

Connecting a Temma motor to the computer

The Takahashi TRS02320 cable provides an RS-232 serial connection between a compatible Temma motor and a computer. The manufacturer lists the Temma-PC, Temma-2, Temma-2M, and Temma-2Z. This connection enables computer control using appropriate software and a driver; however, it does not eliminate the need to configure the software environment.

Two connectors to identify

The cable has a female DB-9 connector on the serial connection end and a Mini-DIN plug on the other end. If the computer does not have a DB-9 serial port, Takahashi notes that a USB-to-serial converter can be added. This converter must be purchased separately: the product listing does not include it with the TRS02320 model number.

Prepare the software control system

The documentation mentions native drivers as well as ASCOM platforms on Windows and INDI platforms on Linux or macOS. Check the availability of the driver that corresponds to your motor and system before connecting it. These instructions describe the documented capabilities but do not guarantee compatibility with all current software versions.

A specific connector, not a universal cable

The physical design of the connectors is not sufficient proof of equivalence with another serial cable. Use the exact part number and the mounting documentation. The length, detailed pinout, and number of contacts for the Mini-DIN connector are not specified in the selected text; no values can be inferred from the photograph.
