SR3 Series
Stealth Microwave’s 19 inch rack mount housings are designed to fit any of Stealth’s current models. The
SR3 Series adds many benefits over our standard module format. LEDs on the front panel monitor normal
operation, thermal or power cautions, and alarms for thermal shutdown, amplifier, VSWR, and fan
failures. The SR series comes standard with a USER PORT (DB15) which provides TTL signals to
monitor the amplifier’s status. The User Port provides analog voltages to indicate the forward and
reflected power levels at the output of the unit and also provides amplifier status and alarm conditions. An
RS-232 interface that performs the functions of the USER PORT is also available.

Description
Returns status of amplifier alarm bit. “On” indicates an over or under
amplifier current condition.
Mode0: “ON” – amplifier failure, “OFF” – normal condition
Mode1: 1 byte, 1 – amplifier failure, 0 – normal condition
Turns amplifier on/off.
Returns amplifiers on/off status.
Mode0: “ON” – amplifier on, “OFF” – amplifier off
Mode1: 1 byte, 1 – amplifier on, 0 – amplifier off
When turned on, transmitted characters are echoed back to the
terminal. No characters are echoed when turned off.
Returns echo state
Mode0: “ON” – echo on, “OFF” – echo off
Mode1: 1 byte, 1 – echo on, 0 – amplifier off
Returns status of the fan alarm bit
Mode0: “ON” – fan failure, “OFF” – normal condition
Mode1: 1 byte, 1 – fan failure, 0 – normal condition
Returns forward transmitted power (Not available in all amplifiers).
Mode0: “0” – “1023” relative to the forward transmitted power
Mode1: 2 bytes LSB first, 0 - 1023
Data mode 0. Return values sent as text (Default).
Data mode 1. Return values sent in binary form.
Returns status of over power alarm bit.
Mode0: “ON” – Amp over rated output power, “OFF” – normal
condition
Mode1: 1 byte, 1 – Amp over rated output power, 0 – normal
condition
