Introduction, ]/ This User's Guide contains the procedures for connecting an Am tech 172611 RF Module, hereafter referred to as the RF module, to an T2020 Reader Logic Card. This document is designed to be used by technical personnel of Am tech and its distributors, as well as authorized customer and third-party systems integration personnel. IT 2611 RF Module Review Figure 1-1 shows the front view of the RF module interface.
T2611 RF Module User Guide 4 Features The RF module receives DC power through an internal power supply that is connected to an external AC voltage source. A separate reader-to-RF module cable carries the demodulated tag signals from the RF module to the reader and the control signals from the reader-to the RF module. Note: Long coaxial cable runs between the RF module and antenna can degrade system performance and should be avoided in system configuration.
Introduction ] Am tech recommends separate frequencies. Am tech can provide units operating at multiple frequencies in the authorized band. Line Driver Output The interface input/output provides balanced low-impedance analog signal lines capable of diving up to 500 ft. of cable. The output incorporates electrostatic discharge protection. Note: Cable lengths over 500 fi. should be used with discretion; longer cables are more susceptible to receiving electrical noise.
Introduction Installing the RF Module 2 This Chapter describes the installation procedures for the RF2611, Including information on equipment, positioning, terminal connections, and grounding. The RF module has dual-antenna ports for transmitting and receiving signals. An additional antenna port is provided for the internal system check tag, In normal mode, an RF module is connected to the reader through its 26-pin circular connector. The following figure depicts the system configuration for normal mode.
T2611 RF Module User Guide Terminal Connections The RF module data-plug connector is a MIL-C-26482 style commercial grade connector with 26 terminals. Figure 10 shows the pin designations for the connector. Figure 10 Twenty-six Pin Circular Connector Showing Pin Designations Figure 1-3 Twenty-six Pin Circular Connector Showing Pin Designations Grounding The CHASSIS terminal is electrically connected to case ground at the factory. Case ground must be connected to earth ground.
Installing the RF Module 2 Brae d Terminal Designations The jack and plug terminals are designated for use as shown in Table 1.
112611 RF Module User Guide Normal Made Connections To install your RE module for operation in normal mode, follow the these directions: 1. Connect power to RF module by inserting connector into mounted plug and tightening sleeve until snug (see Figure 1). 2. Connect transmit and receive antennas to RF module by plugging coaxial cable connectors into appropriate plugs (see Figure 1) and tighten sleeves until snug. 3.
Testing the RF Module ho This chapter provides information on testing the RF module. Testing eg tr Be After connecting the data cable between the RF module and the reader, the RF module should be tested. You will need a data terminal or computer connected to the reader. The RF module has two test points at the transmit and receive antenna ports (see Figure 1).
lod Adjusting the RF Poe 4 This chapter provides information on how to adjust the RF power using reader commands. Adjusting the RF Power RF internal power may be reduced, when.necessary, by IT2020 reader commands. This reduces the internal RF power generated. Refer to IT2020 Reader User Guide for more information. A pad added to the transmit antenna port only decreases RF output power. Tt does not attenuate the incoming tag signal on that channel.
Firmware Commandant 5 This chapter provides the commands needed to control and monitor the status of the RF module. Command Messages The RF module firmware allows the user to control and learn the status of the RF module through commands. A command message contains a two-byte ASCII code, referred to as the command code, which uniquely identifies the command. Optional ASCII data and an ASCII carriage return as an end-of-message indicator follow the command code.
112611 RF Mauled User Guide Command Codes } a The following table contains each of the command codes that the firmware implements.
mm Firmware Commands, } the previous command or command data was invalid and no response data is present in the message. Table 5-1 Response Code Description 0 Command complete 1 Command or command data invalid Command Processing The RF module firmware validates command messages for the command code, data, and data length. An invalid command message causes the firmware to send an invalid response code and no data in a command response message to the ISA reader on the asynchronous serial interface.
T2611 RF Module User Guide 5-6 Set Down link Power The firmware processes this command code by setting the RF downwind power to the state specified by the ASCII command data. Command Code: 02 Table 5-4 Response Code Description 0 Downwind power off 1 Down link power on Get Down link Power The firmware processes this command code by sending a command response message containing the current down link power state, on or off, being used by the RF module.
Firmware Commands Table 5-7 Command Data pied Description 0th-68h 902-928 Frequency offset from 802 MHz in.25 MHz resolution Set Down link Frequency The firmware processes this command code by setting the down link frequency to the value specified by the ASCII command data. The firmware sends a command invalid response code if either the up link or down link power is on when attempting to change the down link frequency.

Command Code: 05h Table 5-11 Command Data Description 0th-OFh Up link attenuation in dB Set Down link Attenuation The firmware processes this command code by setting the down link attenuation to the value specified by the ASC command data.
— Get Down link Attenuation The firmware processes this command code by sending a command response message containing the current down link being used by the RF Module. " Command Code: OBh Command Data Description 0th-0Fh Down link attenuation in dB Set Check tag State The firmware processes this command code by setting the check tag to the stair specified by the ASS command data.
