What is the DC power input for FS-GF801?

The main-board of FS-GF801 needs the power-input is DC 19V, so we provide the adapter with AC 110~240 input & DC 19V output.

FS-GF801 related development software.

please be advised that the operating system of FS-GF801 smart reader is Linux (Debian 5.0.3, default, free of charge) or Window XP embedded (with extra US$100 license cost).  The programming language for Linux is C/C++, and the programming language for Window XP embedded is Microsoft Vitual Studio.NET.

To provide HW with full frequency band (840-960MHz) and to use S/W to control operation frequency for different country standard (such as ETSI or FCC)

There is no “software only” method for this purpose currently, the frequency to be used are defined in firmware in the module. After discussed with our engineer, we realize that it is useless to have a full-frequency HW module because you need to change your reader antenna with ETSI or FCC standard in your handheld reader.  We decide to keep our current product policy, to provide module which can pass certificate, FCC or ETSI, and we will not provide module with HW spec of full-frequency band and customer can select frequency band by SW.

To use parameter to control LBT and Frequency Hopping operation.

We provide standard LBT and Frequency Hopping operation, and it is also defined in the Firmware and customer cannot select by SW.  We will not provide SW which do not meet regulation.

Power management related issues (power on/off control, power saving …)

please refer to programming guide for power saving mode. The current benchmark for  consumption is 40mA after CPU power up, 250mA after RF Module is ready and 1.2A~1.6A for whole system in command operation (with Tx power of 30dbm).  You can turn off the whole RF Module to reduce the power consumption to around 40mA.

Is the a single module that can be used worldwide or are there frequency range specific modules?

Please be advised that all our UHF products are hardware based. As a result, we can only provide FCC or ETSI frequency for our customers instead of worldwide frequency. Thank you for your understanding.

Will there be a module with an industrial temperature range (-20 .. +85 degree Celsius)

FS-GM102 industrial temperature is -20~+60. Please be advised that it is mainly the IC that will automatically shut down if it  goes beyond 60 degree. You probably need to have a special cooling system to place under the module to prevent the product from overheating.

To have “Power Setting” function in SDK

Yes, we do have “Power Standby Method  “ in programming guide, page 54.

how to set “duty cycle

We already optimized the duty cycle in our system for best power consumption and performance. 65% is current fixed value for duty cycle.

Does it support DRM (for EU/ETSI region)? On the front page of the flyer (FS-GM102-20090409-V1-1) it says it is supported, on page 2 it says N/A

Please be advised that FS-GM102 does not support DRM. The hardware does not support DRM but we do support the software to enable listen before talk and frequency hopping. For your information, our FS-GM801 supports DRM both hardware and software.

Does the module need to be mounted on a carrier board for electrical connection? Total height is important in our application

FS-GM102 is reader module only because this product is mainly to be embedded for handheld reader. This is not a standalone reader so you need to connect to our handheld reader or a computer. If you are going to connect directly to a computer, you need to have housing for heatsink. As for our FS-GM801, it already contains an OS, which means it is already a computer with housing.

Is the reader limited in some way e.g. no detection when communicating with the host, < 100% RF duty cycle to reduce power consumption etc. (we cannot afford uncontrolled gaps in detection)

Please be advised that as long as your heatsink housing is good, there should be no problem on detecting when communication with the host. It can go 100% duty cycle. For your information, FS-GF801 is more stable since we already taken care of the heatsink and it is a finished product.

Does the module give access to low level EPC Gen2 protocol settings (e.g. Q factor, session number etc.)
