2. Software Control Overview This Software is used for all GMS products based on VETA Receivers, including VR, VMR, MVRD and MVMR. However each product uses specific control cable. Control cables, as well as connector pin outs, are described in details in corresponding product manual. Configuration, control and monitoring of the VETA Series Receivers are enabled through the use of GMS’ optional (sold separately) MS Windows-based VETA RX Configurator software program (GMS Part Number 630-SW0093*).
2.3 Product Control & Status Monitoring Approach GMS Transmitters and Receivers provide programmable presets or configurations that can be set up through special programming software by Administrators. Configurations are selected by the user though M.S. Windows Application programs. The VETA products allow 16 configurations. Administrators define the configurations for specific applications.
Figure 2 – VETA RX GUI Main Screen 2.5 Access levels As was mentioned previously, VETA Control Software has 2 levels of access – User and Administrator. To have full access to the controls, it is necessary to enter password provided by GMS into the Administrator Login window, which is located under Options pull-down menu. The password can only be changed by the factory. User Level Access only allows changing the predefined configuration groups. 2.
After changing any “R/W” field with a new value the user must click on the APPLY button for the change to take effect. Clicking on the CANCEL button (or Query button) will cancel the operation (previous values are restored). Field R/W Description R/W RF input frequency at BDC (block down converter) input. The receive frequency can be changed by entering the new desired frequency in this field. R/W This field displays the bandwidth of the received OFDM signal.
Field R/W Description R This read-only field conveys the BER (Bit Error Rate) of the received signal after Read-Solomon (Outer Code) Forward Error Correction (FEC) processing and before Viterbi (Inner Code) FEC processing in the receiver chain. Value expressed in 10-6. BER Post Viterbi R This read-only field conveys the BER (Bit Error Rate) of the received signal after performing all error correction techniques in the receiver chain. Value expressed in 10-6.
Any field which is an R/W (read/write) can be and is stored in a configuration group. A group is selected by choosing one of the 16 groups and then clicking on the LOAD button. This action loads all R/W fields (under any of the TABs or pull down menus, not just the MAIN PAGE TAB) with the stored values of that group. A group can be changed by editing an R/W field and then clicking on the APPLY button (“APPLY” also automatically saves).
Figure 3 – BDC Settings Window Field LO (MHz) Down Converter LO side BDC Power BDC Gain Setting R/W Description R/W This field allows definition of the local oscillator FREQUENCY of the BDCs (block down converters). R/W This field allows definition of the local oscillator side. Values are either HIGH or LOW side injection. High side injection means the LO is at a higher frequency than the RF. So if ‘RF freq’ – ‘LO freq’ = IF freq, then the IF Freq will be negative or the spectrum will be inverted.
Figure 4 – Video Settings Tab Field R/W Description Power-up Video Format R/W This field allows user to select between PAL, NTSC or NTSC with a 7.5IRE pedestal. NOTE: The VMR will automatically switch to the video format that it is locked onto (PAL or NTSC). NTSC Format R/W This field has two choices NTSC and NTSC with pedestal R/W This field allows the user to select between a blue field video output (a YES value) or a freeze frame (a NO value) when no video is present.
Field R/W Description TX Video Input Lock R Shows if incoming signal is locked on Video Video PID R Shows the Video PID of TS Audio PID R Shows the Audio PID of TS Table 5 – Video Status 2.6.7 Security Tab This tab allows administrator to enable or disable encryption, to choose type of encryption to be used and enter the encryption key; ABS (supplied with link) and optional AES or Bcrypt. AES and B-crypt have 4 sub selections: 128, 128+, 256 and 256+.

Field R/W Description Encryption R/W This field allows user to select between OFF, ABS, AES 128, AES 128+, AES 256 or AES 256+. (AES 128 and 256 are optional). Key R/W This field allows user to enter the proper number of characters for the encryption key. Table 6 – Encryption Field Definitions 2.6.8 User Data Tab This tab (see Figure 7) allows user to turn USER DATA ON or OFF. If turned ON, the receiver extracts any User Data component that may be in the transmitted stream.
Field R/W User Data Description R/W This field allows user to select between ON & OFF values. When the control is set to ON, the user can extract RS232 data from the data output port (J2 pins 8 & 9) of the receiver. R This is a read only field that reports the baud rate of the RS232 data component that is present in the transport stream. Data Baud Rate Data Parity R/W User can choose from None, Even or Odd. Data PID R/W Shows the Data PID of TS Table 7 – User Data Field Definitions 3.
Figure 8 – Options 3.2.1 Special Setup Special Setup is configured at the factory for specific application and for advanced operations only. Consult GMS before changing any of these parameters. This selection brings up a window with special parameters (see Figure 9). Selections are described in Table 8. Figure 9 – Special Setup Field R/W Input Mode R/W This field allows the user select between RF input and Chaining Input.
Field R/W R/W OSD Mode Description The selections are Standard OSD (see Figure 10 ), Alarm OSD Banner (displayed only when receiver is not decoding), Others (Advanced OSD). Table 8 – Special Setup Parameters Figure 10 – Standard OSD 3.2.2 BDC Settings Clicking on this selection opens up the BDC Settings window. This window was previously discussed in section 2.6.5. 3.2.3 Polling Options In this window the user can set the polling interval (in ms). 100-M0131X1A 02/10/10 20 of 31 www.cobham.
Figure 11 – Polling Options 3.2.4 Administrator Login Administrator Login allows the user to access more selections by entering password that can be obtained from GMS. The password cannot be changed. 3.2.5 Load Configuration File This is a special feature that allows the Administrator to change all the parameters of the unit at once. GMS provides Configuration File that can be modified before loading into the unit. Examples of Default Configurations File for VR-s are shown in Table 9 and Table 10.

4. Control Protocols The following section describes the control protocol employed on the RS232 link for controlling the VETA transmitters and Receivers. Refer to corresponding manuals for low level commands list. 4.1 RS232 Control The physical interface is RS232. Normal operation involves sending a packet from the control device (normally a PC) to the device being controlled. If the packet satisfies an address integrity check, then the controlled device will action the command and send a reply.
