Zaxcom ERX and ERX-TCD Overview ERX The Zaxcom ERX will receive IFB audio and display timecode, Scene ID, Take # and user-bits. A time code hold function is included to aid script supervisors so that they can easily note timecode and metadata. The ERX also features onboard SMPTE timecode reader/generator. ERX-TCD The “TCD” adds the ability to output a timecode signal from the headphone jack. This can be used to send time code to a camera or slate.

ERX Control Keys • MENU – When in Extended Menu it is used to advance to the next menu item. When Alternative IFB is enabled it is used to change receive frequencies. • INC (up arrow) – Used to increase the parameter of a menu item. It is also used to toggle between time code, scene, take and user bits embedded in the meta data. • DEC (down arrow) – Used to decrease the parameter of a menu item. It is also used to toggle the display between time code, scene, take and user bits embedded in the meta data.
ERX Main Display 01:02:03:04 S: (SCENE INFO) T: (TAKE INFO) UB 00:00:00:00 The main screen of the ERX will display TC battery level and receive audio level. If you are receiving signal from a Zaxcom recorder you can also display the Scene, Take and User-Bits by pressing and holding the INC or DEC key.
Setting up your ERX in the Extended Menu NOTE: All settings changes are saved in to the ERX’s flash ROM and remembered Accessing the Extended Menu 1. Press and hold the MENU key while powering up the unit. 2. Pressing the MENU key will advance to the next menu item. 3. At any time if you press and hold the menu key you will be taken back to the top of the Extended Menu. Exiting the Extended Menu • Cycle the power. Or • Hold down the MENU key to get back to this page and press the INC key.
IFB Frequency FREQ: 2.403 RX SIGNAL: A01 B01 When the ERX is receiving a signal RX will be displayed. Signal strength. Signal strength indicator This is the frequency the ERX’s will receive audio, time code and meta data on. To adjust the frequency press the INC and DEC arrows to match the frequency your transmitter is set on. You can choose any frequency form 2.403GHz to 2.475GHz The signal represents the strength of the ZaxNet signal that the ERX is receiving.
IFB Voting Enable IFB VOTING: NORMAL (OFF) This enables / disables the IFB Voting function. The purpose of the voting is to allow the ERX to choose and switch to the stronger signal from two different ZaxNet transmitters. One purpose of this is if you are on a large set you can place a second transmitter at a different location and the ERX will choose the stronger signal. Just set the second transmitting frequency a minimum of 2MHz higher than the first unit.
Time Code Jam Mute - (ERX-TCD Only) TCJAM MUTE TIME: 0MS (DEFAULT) This menu sets how long the time code output will be paused when the time code is being jammed. When this is set to on the time code output will mute for the duration selected whenever the ERX sees a jump in time code of more than 2 frames. This simulates removing the time code completely from a device and plugging it back in so that the receiving device recognizes that there is new time code.
1K Notch Filter Frequency This menu will only appear if you enable the 1K notch Filter 1K NOTCH FREQ 1000 HZ This allows the ERX to adjust the notch frequency if the tone generator feeding the ERX isn’t exactly at 1 kHz. This can be set between 960Hz to 1040Hz in 2Hz steps. ZaxNet Output Enable - (ERX-TCD Only) ZAXNET OUTPUT OFF This enables / disables passing Zaxnet commands embedded within the time code output.
Alternative IFB Frequency ALTERNATE IFB FREQ: 2.420 This allows you to set a second receive frequency so a listener could toggle between multiple receive frequencies from different ZaxNet transmitters. To listen to the alternative frequencies: • From the home screen press the Menu key - the current receive frequency will be displayed • Then toggle through the frequencies by pressing the INC and DEC keys. • The metadata displayed will be corresponding to the transmitter being monitored.
Quick Start Guide: Interfacing Your ERX-TCD with a Nomad 1. In the main menu of Nomad select ZaxNet Setup 2. Scroll down and select Input Configure. Make sure that the input configure is set to 8 or higher. Press the back button and return to the ZaxNet Setup Menu. 3. Power cycle your Nomad 4. Return to the ZaxNet setup menu scroll up and select IFB Mode. Make sure that it is set to TX or TX+RX 5. Scroll down and select your transmit channel and choose which frequency you’d like to transmit on.
Firmware Each unit is shipped with the latest firmware version installed. As newer firmware becomes available, it can be downloaded from the Zaxcom website: http://www.zaxcom.com/software-updates Newer version of Beta software may be found on the Zaxcom Forums: http://www.zaxcom.com/forum Each time a unit is powered up, the firmware version number is displayed briefly on the LCD screen. Pressing the DEC key during the boot up will slow down the screen to allow easier viewing of the information.
Updating ERX Firmware (using an TRX Transmitter) NOTE: You need a TRX-900 or similar devise that has an IFB option and the TRX needs to be running software version 7.02 or higher. 1. Format a media card in the TRX transmitter. 2. Using a computer with a MiniSD card adapter, perform the following: • Delete the “DELETE.ME” file on the card. • Download the ERX software and load it into the card. 3. Insert the card into the TRX. 4. Insert a fresh set of batteries into each ERX. 5.
