For maximum durability of RJ45 cables, BUFTEK uses and recommends flat, stranded conductor, cable and

RJ45 8x8 (8-pin) connectors designed specifically for this type of cable. This is the basic type of cable used

for telephone handsets, and is designed to reliably withstand extreme physical and environmental conditions.

Cables made with solid conductor wire and/or connectors designed for solid conductor wire (often used for

CAT5 and CAT6 data cabling) tend to be intolerant to the constant flexing that control panels tend to receive.

In short, solid cable is unreliable and not recommended - use stranded cable and the correct RJ45 connectors.

Most interconnection of BUFTEK controllers uses 1-8 to 8-1 conductor order, meaning the connectors are

both crimped onto the flat wire on the same surface, resulting in a reversal of conductor order from one end

to the other. This is standard for telephone applications, but not for data, which tends to be pin-for-pin.

This conductor reversal, should be confused with a CAT5 “crossover” cable, which crosses over different

conductor pairs and will not work in BUFTEK applications. However, some BUFTEK cables use pin-for-pin

conductor order, and some cables must have certain pins disconnected to avoid the interconnection of power

supplies or data signals.

All BUFTEK controllers and SD Sport Replay Systems have the following pinout on the RJ45 AUX connector:

(RJ45 connector pins count from the left looking into a female connector with pins on top, or looking at a cable

connector’s conductors with that end of the connector pointed up)

RJ45-8: Controller RS-422 TX- (“9-PIN” DE09 connector Pin-8)

RJ45-7: Controller RS-422 TX+ (“9-PIN” DE09 connector Pin-3)

RJ45-2: Controller RS-422 RX- (“9-PIN” DE09 connector Pin-2)

RJ45-1: Controller RS-422 RX+ (“9-PIN” DE09 connector Pin-7)

RJ45-3: Controller RS-422 Ground and Power Supply Negative (”9-PIN” DE09 Pin-4, 6, 1 - shield)

RJ45-6: Power Supply +12VDC (Amperage varies per application)

RJ45-5: Modified RS-485 TX/RX+ (used to communicate with TBar)

RJ45-4: Modified RS-485 TX/RX- (used to communicate with TBar)

Note: These pinouts are on the controller side, when a reversing order

cable is used (like in the case of a VTA-2001 to adapt to a 9-pin)

the conductor order on the adapter side is reversed.
