1.2.25 Hardware Preset Option
– PS2, PS4, PS8, or PS16
The TIMTER™ supports one or more hardware presets. A single preset defines the complete state of the transmitter,
including carrier frequency, modulation mode, data polarity, randomizer state, etc. Without the PS option, the
TIMTER™ supports only one hardware preset, which it reverts to at power-up. The PS in the option string specifies
that the unit supports multiple hardware presets (2, 4, 8, or 16). Presets are engaged by grounding various
combinations of pins on the terminal/parallel control selection. The number of presets available and which pins
engage the presets depend on the other features specified. Due to the limited number of pins available, the PS option
may require the elimination of the RF On/Off pin. Due to firmware part number parsing requirements, the hardware
preset option code must be at the very end of the part number to be valid. On units which use the standard MDM-15
connector, the ZY command displays the connector pinout showing preset pin locations. For more information, refer
to Appendix A – Preset Option.
1.2.26 Power Output Option
– PW020
When ordered with Power Code 00, this option enables RF output at 20 mW (+13 dBm).
1.2.27 Spacecraft Tracking and Data Network Option
– STDN
This option supports the PM/BPSK mode (Spacecraft Tracking and Data Network mode).
1.2.28 Variable FIFO Depth Option
– VF
This option enables the VF command which allows the user to set the FIFO depth on the transmitter for controlling
latency time between bits in and bits out. The range is 0 to 255 with 128 being the default. If no value is entered, the
current value displays.
1.2.29 Variable Power Option
– VP
The standard TIMTER™ operates at its full rated RF output power. The software-based VP option provides 32
discrete power level settings, spanning a range of as much as 24 dB. The steps are non-uniform, but steps are
typically no larger than 1.1 dB.
1.2.30 Wide Input Voltage Range Option
– WV
The standard nanoTX™ operates from +28 + 4 VDC. The WV option extends operating input voltage range as
shown in following table.
Voltage Ranges with WV Option
+6.5 to +34 VDC for 1 Watt version
+6.5 to +34 VDC for 2 Watt version
+12 to +34 VDC for 5 Watt version
+21 to +34 VDC for 10 Watt version
