Installation and Setup, cont’d Operation Power Input 1. Connect the captive screw connector from the supplied 12 VDC power supply into the power receptacle. N POWER 12V 0.6A MAX The FOX 2G Tx/Rx AV does not have a remote powering feature. Both the transmitter and the receiver require their own separate power supply.
Video Connections The FOX 2G Tx/Rx AV accepts a single low resolution video signal (composite, S-video and low resolution component video) and outputs a single low resolution video signal (composite, S-video and low resolution component video). It is not compatible with RGB or HDTV 480p, 720p, or 1080i component video signals. The transmitter converts incoming signals to a proprietary format and passes them along the fiber optic cable to the FOX 2G Rx AV.
Installation and Setup, cont’d Audio Connections Audio input to the FOX 2G Tx AV and audio output from the FOX 2G Rx AV are made through the 3.5 mm, 5-pole, captive screw connectors. Input and output can be mono or stereo and can be balanced or unbalanced, depending on the wiring connections (see figure below).
Alarm ALARM The alarm pins, labeled 1 and 2, (see figure at right) on the rear panel of the FOX 2G Tx/Rx AV act as a short when activated. They do not produce any discrete on/off voltage signals but, instead, act as an internal relay that will either connect or disconnect an external alarm circuit. 1 2 For the FOX 2G Tx AV, the alarm state is activated when link 2 is absent. For the FOX 2G Rx AV, the alarm state is activated when link 1 is absent.
Installation and Setup, cont’d Fiber Optic Cable Connector The transmitter and receiver units of the FOX 2G Tx/Rx AV are connected by an LC duplex SFP connector. Fiber optic link 1 connects the Tx port of the transmitter and the Rx port of the receiver. It carries video, audio and/or data output from the transmitter to the receiver. OPTICAL Tx Rx Fiber optic link 2 connects the Tx port of the receiver with the Rx port of the transmitter.
Daisy Chain Capability FOX 2G Rx AV receivers have a loop-out mode that allows a signal to be passed from the receiver along a daisy chain of to up to ten receivers, with a display device attached to each receiver. The loop-out mode is set using RS-232 commands. For more information, see chapter 3, "Simple Instruction Set (SIS) Commands". All receivers in the daisy chain must be compatible, i.e. they must all be SM or all be MM models, connected with the appropriate fiber optic cable.

FOX 2G Tx/Rx AV 3 Chapter Three Configuration RS-232 Ports RS-232 Control of Tx and Rx Units Simple Instruction Set (SIS) Commands Command/Response Table for SIS Commands Windows®-Based Control Program
Configuration RS-232 Ports Both the FOX 2G Tx AV and FOX 2G Rx AV have a front panel TRS port and a rear panel captive screw port, which can provide SIS commands to configure the tranmitter/receiver settings when connected to a control device. SIS commands for the FOX 2G Tx/Rx AV are shown (starting on page 3-8). N The two comm ports work in parallel. However, depending on the computer or the communication settings, connecting to both comm ports at once may result in one or both ports not working.
As an alternative to the front panel TRS port, the RS-232 Remote port, on the rear panel, uses three connectors in a 5-pole captive screw connector.
Configuration, cont’d RS-232 Control of Tx and Rx Units When the FOX 2G Tx/Rx AV is configured by RS-232 commands, some commands are processed by the transmitter and others are processed by the receiver. The SIS commands do not distinguish between the two units. The system routes the commands based on where they are processed.
Simple Instruction Set (SIS™) Commands Introduction to SIS SIS commands consist of a string (one or more characters per command field). For the FOX 2G Tx/Rx AV, apart from setting audio gain ("G") and attenuation ("g"), upper and lower case characters may be used interchangeably. Commands do not require any special characters to begin or end the command string. Each response from the unit ends with a carriage return and a line feed (CR/LF = ]), which signals the end of the response character string.
Configuration, cont’d Symbols used in this manual When programming in the field, certain characters are most conveniently represented by the hexadecimal equivalent of their ASCII value. For convenience, the table below shows the hexadecimal equivalent of each ASCII command: ASCII to HEX Conversion Table Space . N Apart from G (gain) and g (attenuation), upper and lower case characters can be used interchangeably in SIS commands for this product.
X$ — Output video type 0 = Follow input type 6 = Component 7 = S-video 8 = Composite X% — Audio gain (0 to 10) X^ — Audio attenuation (-18 to 0) X& — Audio level (-18 to +10) X* — Audio output level 0 = Consumer level (-10 dBV) (default) 1 = Professional level (+4 dBu) X( — Test pattern 0 = Test pattern off 1 = Color bars 2 = Grayscale 3 = Alternating pixels X1) — Link #2 transmission status 0 = disables link #2 1 = enables link #2 from receiver back to transmitter 2 = enables daisy chain mode on receive
