## Summary description

SATEL RJ/PIN3 is an adapter for RS‑232 TTL interfaces that converts an RJ connector to a 3‑pin header (PIN-3). It enables connection between devices using RJ‑style cabling and equipment requiring a 3‑pin TTL serial connection. Useful for installers and service technicians when wiring alarm panels, controllers or modules with differing serial connector standards.

## Long description

SATEL RJ-to-PIN3 (RJ/PIN3) is an RS-232 TTL adapter that converts an RJ-style connector to a 3-pin TTL serial header. Designed for linking devices that use RJ cabling with equipment that requires a 3-pin TTL serial connection, this adapter simplifies wiring tasks in installations where connector standards differ. It is a compact passive accessory intended for installers and service technicians working with alarm panels, access controllers and serial modules.
Advantages
The adapter provides a straightforward electrical conversion between an RJ connector and a 3-pin TTL header without active signal conversion, preserving the TTL voltage levels expected by compatible devices. Its small form factor makes it easy to include inside enclosures or junction boxes. Using this adapter reduces the need for custom cable assemblies and minimizes installation time when adapting RJ cable runs to 3-pin serial inputs.
Suitable for
 Connecting alarm control panels to peripheral modules that use 3-pin TTL serial headers
 Adapting RJ-style cabling to access control units and controllers with TTL serial pins
 Field service and maintenance tasks where quick conversion between RJ and 3-pin serial is required
 Prototyping or bench testing devices that accept TTL-level serial signals via a 3-pin header
Key specifications
 Interface type: RS-232 TTL signal level compatibility
 Connector A: RJ-style connector (for RJ cabling)
 Connector B: 3-pin header (PIN-3) for TTL serial
 Function: Passive adapter for wiring conversion between RJ and 3-pin TTL
 Physical form: Compact inline adapter suitable for mounting inside enclosures
How to use
Insert the RJ connector into the adapter's RJ socket and connect the 3-pin header to the device requiring the TTL serial connection, ensuring correct orientation of the header pins. Confirm that both connected devices use compatible TTL voltage levels and the expected signal assignments (TX, RX, GND) before powering the system. No external power or configuration is required for the adapter itself; it functions as a passive wiring interface to route the TTL signals between the RJ cable and the 3-pin header.
Usage recommendations
Verify pinout and voltage compatibility before installation to avoid signal mismatches. Use short cable runs or shielded wiring where electromagnetic interference may affect TTL-level serial communication, and secure the adapter inside enclosures or with strain relief to prevent connector stress.
