The Broadcast Tools Mono/Stereo 6 X 1 "B" Switcher/Router w/Serial Control The 6 X 1 "B" is available with a rack panel adapter, but we recommend that it sit on top of your studio console for manual operation in addition to remote control with CartReady. A detailed bound manual is included from Broadcast Tools which provides detailed information for audio connections. There are two methods of Control. One is via relay, the other is via RS-232. We recommend RS-232! Relay Control Operation with ControlReady: (Connection to USN1616 summarized:) The BT-6X1 "B" switcher utilizes a MALE 15 pin connector for remote control. Control for each channel is via a TTL/CMOS pin which has been pulled high. When you short the pin to ground it causes the 6 X 1 to switch to that channel. The system is interlocked, so shorting another one moves to the next channel. If you ever short more than one pin at a time to ground, nothing will pass until you release one of the pins. We recommend 100ms pulses for proper switching. Pin 1 is Channel 1, Pin 2 is Channel 2 etc. 15 is grounded for easy cross connects. We've included a pre-made cable designed for easy connection to the 16x16. It has been presoldered into pins 1 thru 6, and 15 which is for ground. Pin 13 is the Clear/Mute channel. Each channel control connection to the 16x16 is as follows: 6X1 INPUT PIN -----> N/O RELAY OUTPUT ON 16X16---------| 6X1 GROUND PIN <-----COMMON RELAY OUTPUT ON 16X16-------| When you set a command in a CartReady Playlist such as PULSE B1-A HI 100ms, relay "A" on the USN16x16 controller closes momentarily. The N/O output will connect to COMMON which is wired back to a ground pin on the 6 X 1 thus grounding the INPUT pin on the 6 X 1. Thus the 6 X 1 will switch to that channel and pass audio from channel one out the switchers output. A cable has been supplied with the following pins connected. The hood has been left off so you can see which color is connected to which pin on the SWITCHER. You can put the hood on at your convenience. Note: Pin-outs were changed as of 7/20/95 to those below.

Each pair controls the specific audio channel on the switcher, i.e #1 and 15 control CH 1. We've suggested which relays on the USN1616 to connect, but this is up to you. For example, if you connect 1 and 15 to 54 and 55 on the USN1616, you need to PULSE B1-A for 100ms to switch to CH1 on the switcher Logic: The PULSE B1-A command closes 54 and 55 on the USN1616, which switches to CH 1. The #'s mentioned for the USN16x16 controller are the COMMON and N/O contacts for relays 1 thru 6 respectively. TECHDOCS\INSTALL\6X116X1B.INS 1 of 2 2/97 C Cabling Worksheet We offer a pre-made, tinned cable that lets you easily connect the 6x1B switcher to our USN1616 controller. You can make one yourself, or you can order one pre-made from us. Name: USN1616-BT6X1 "B" Cable Purpose: Plug and play cable connection between USN1616 controller and Broadcast Tools 6X1 switcher/router used with CartReady Connectors: First end: DB15 FEMALE Other end: No connector, just stripped and tinned. Pin outs: 1 ________________ Red 2 ________________ Green 3 ________________ Blue 4 ________________ Brown 5 ________________ Orange 6 ________________ Pink 13 _______________ Yellow 15 _______________ Red&Black, Blue&Black, Green&Black, Brown&White, Orange&Black, Pink&Black, Yellow&Black Functional: 1-6 are the inputs to select channels 1-6 respectively. When you hit short 1 to ground, it switches, etc. 15 is the only ground point available on the 6X1 for signal returns. In this manner, you pair a signal wire with a ground and connect them to the common and Normally Open (NO) contacts on each relays of the 16x16 controller. When ControlReady tells a relay to PULSE, the USN1616 relay pulses and thus causes the switcher to switch. TECHDOCS\INSTALL\6X116X1B.INS 2 of 2 2/97 C RS-232 Control The second manner of control is via any RS-232 COM port on your computer. Simply connect the RS-232 cable to RJ phone jack inside the unit at one end, and the other end to a 9 PIN COM port on your computer. To control the switcher, use the COMTALK command in the ControlReady automation deck(s) The command string is as follows: *[source][C/R] Where source is the channel 1 thru 6 [C/R] is ASCII 13 You hold the ALT key down, then hit the 1 on the numeric keypad, let go of 1, then hit 3 on the numeric keypad. Then release the ALT key. Note: Numlock has to be lit. If you do this right, it shows up as a musical note on the screen. You don't actually type the [ or ] characters at any time. You can also set up a command to mute the switcher. *M[C/R] again don't ever type [C/R] you subtitute ASCII 13 for this. The other settings of the COMTALK command refer to the hex address of the COM port you are using, ex. COM1 is 3f8. Baud rate should be set at 2400 baud. N81 protocol. Intercharacter delay is 0 Lastly, we STRONGLY suggest you setup CUSTOM COMMANDS. You hit F10 OTHER and choose ASSIGN CUSTOM COMMAND. This way you can create a command called SWITCH TO ABC for example which stands for COMTALK 3f8 2400,n81,0 "*6[C/R]" You're programming will read alot more friendlier, and you'll save alot of keystrokes using custom commands. You can setup a custom command for each source, and mute.
