Item # RFLS-9HSRCXP RapidFire-6 Dual Battery Receiver w/ Ext. Terminals 9V, 1A

The RFLS-9HSRCXP RapidFire-6 Dual Battery Receiver w/ Ext. Terminals is a highly sensitive narrow band (superhetrodyne) radio receiver designed to be used for remote control applications where low latency and high reliability are critical. When used with the Holatron model RFLS-6HSXT, RFLS-12XT or RFLS-12XTX transmitter, a range of ½ mile (line of sight operation) is typical, provided there are no intervening conductive objects such as automobiles, chainlink fences, etc. Range increases as the receiver is elevated above earth or other conductive objects (such as aluminum bleachers). Range will be even greater when transmitting over water.

The reception carrier frequency is fixed at 418 or 433 MHz by a SAW (surface acoustic wave) oscillator for exceptional stability. No alignment or tuning procedures are ever required to maintain optimum performance.

The receiver's firing signals are digitally decoded from the transmitted digital code which is amplitude modulated on a single carrier frequency of 418 or 433 MHz. The transmitted digital code indicates to the receiver which cue number is being fired in single-shot mode or whether an automatic-fire command is being transmitted from the "B" button on an RFLS-6HSXT transmitter. The manner in which the received code applies 9 volt firing pulses to the six outputs is determined by the setting of the digital channel switch.

Transmitters that are set to separate digital channel numbers can transmit simultaneously to separate receivers without interfering with each other. There are six digital communication channels which permit up to six different receivers or groups of receivers to be controlled by separate transmitters simultaneously. Note that a receiver’s digital switch setting must correspond to the digital communication channel of the transmitter controlling it.

Semi-automatic and automatic firing sequences will restart at cue 1 after passing cue 12. Receivers set to switch positions 1 - 6 will only fire on cues 1 - 6. Receivers set to switch positions 9 - E will only fire on cues 7 - 12. Thus, it is possible to set two receivers to fire a total of twelve cues on the same digital channel. Multiple transmitters and receivers may communicate simultaneously, provided the transmitters are all set to different digital channel numbers. Transmitters set to the same digital channel number will interfere with each other and possibly result in failure-to-fire.

Power is supplied from two alkaline 9 volt batteries, inserted into snap-in cases on top of the PC board. In this configuration, receiver power and firing power are derived from separate 9 volt batteries. In order to prevent the possibility of damage due to battery leakage, the battery should always be removed if the transmitter is to be stored for a prolonged period. Damage due to battery leakage is not covered under the warranty.
