Connecting KEYIN and KEYOUT:
IMPORTANT: The KEYOUT line is an open collector circuit capable of 45V @ 800mA maximum. If the open
circuit voltage is more than 48 volts or negative, a keying buffer must be used between uLINK DATA
module and the amplifier. All modern amplifiers including all solid state power amplifiers can be
switched directly without a buffer.
Connecting SteppIR:
The original SteppIR controller MUST be switched into the GENERAL mode. Manual band changes on
controller front panel are disabled. Autotrack must be turned on with the SDA-100. Use 9,600 bps or lower for
reliability. The uLINK DATA RS232 port must be connected with the SteppIR DATA OUT port using three
connections: pin 2 to TX, pin 3 to RX and pin 5 to GND, shielded cable is highly recommended.
DO NOT make any other connections to SteppIR's DATA OUT connector.
Due to software issues with early versions of the SteppIR transceiver interface controller, it is not possible to
keep Station Master Deluxe and the SteppIR controller in sync if changes are made using the SteppIR local
controls. If you make changes using the SteppIR controller, it will be necessary to "undo" the function (¾, wave,
bi-dir, 180, band change, etc.) on the SteppIR controller.
Connecting UltraBeam:
Baud rate must be set to 19200 bps and function to Ultra Beam. The uLINK DATA RS232 port must be
connected with the UltraBeam Serial port using three connections: pin 2 to RX, pin 3 to TX and pin 5 to GND,
shielded cable is highly recommended. There must be a jumper between pins 4 (DTR) and 8 (CTS) on the Ultra
Beam cable end.
Connecting Acom 2000:
Baud rate must be set to 1200 bps and function to Acom 2000. The uLINK DATA RS232
port must be connected with the Acom serial port using three connections: pin 2 to TX,
pin 3 to RX and pin 5 to GND; shielded cable is highly recommended. The OPT output
can be used directly for the PA power on function when connected between pins 1 and 5
of REMOTE connector.
