ATOM 100-250W BUC & SSPA Revision 2.2 908236 Section 2.2 J1, J5, & J6– I NPUTS AND ROUNDING J1 – IF/RF I NPUT The IF/RF input connector is a 50 ohm coaxial connector (N or SMA Type). This connector is NOT DC- blocked, and appears as a 50 ohm load at DC.
ATOM 100-250W BUC & SSPA Revision 2.2 908236 Section 2.3 J3 – DC/AC P OWER The 100W ATOM power input requires either 20V to 56V DC power (DC unit) or 3-phase 208V AC power (AC unit). On the other hand, 250W ATOM power input requires 36V to 56V DC power. Each ATOM is supplied with a mating connector for the power interface.
ATOM 100-250W BUC & SSPA Revision 2.2 908236 For the DC input units, the positive terminals are pins B/C and the negative terminals are pins A/D. Pins A and D are connected to case ground internally; pins B and C are connected together internally. It is recommended to apply the supply voltage evenly to both pairs of pins to evenly share the current among both sets of wires/pins.
ATOM 100-250W BUC & SSPA Revision 2.2 908236 Section 2.4 J2 – M ONITOR AND ONTROL NTERFACE The M&C interface is used to control the unit with a host computer. All on-board sensors are accessed through this interface. Use of this connection is optional. Each ATOM is supplied with a mating connector for the M&C interface.
ATOM 100-250W BUC & SSPA Revision 2.2 908236 Table 2-4 summarizes the various pinout options for the 100-250W ATOM. Note that the pin function varies according to the M&C interface option that the ATOM was ordered with. The M&C interface option cannot be changed by the user.
ATOM 100-250W BUC & SSPA Revision 2.2 908236 Mute Control: Pin D This pin controls the hardware mute state of the ATOM. When muted, the power transistors are turned off, reducing power consumption and providing an RF output noise close to the thermal noise floor. The operation of this pin is fully configurable through the M&C Interface.
ATOM 100-250W BUC & SSPA Revision 2.2 908236 The RS-485 address pins each have a 10K-ohm pull up to 3.3V. If RS-485 addressing is not used, pins E, F, & K should be left floating (i.e. disconnected). Table 2-6 summarizes the unit address assignment configuration; 0 denotes a grounded pin and 1 indicates a floating pin.
Note that it is possible to use an RS-232 interface to control a standard configuration equipped ATOM through an RS-485 to RS-232 adaptor. Contact Norsat for details about the available adaptor kits. (RS-485 & RS-232) ERIAL...

ATOM 100-250W BUC & SSPA Revision 2.2 908236 The command format for Non-addressed Commands is as follows: <cmd><CR> Only a carriage return character is required for Non-addressed Command termination. In both cases, the <cmd> string is a command word (in ASCII text) followed by zero or more sets of parameter-value pairs.
