WR-CCH Contact Closure/Logic Interface What is it: The WR-CCH is an all-purpose connection device between a computer running CartReady and the outside world. You CAN DO ANYTHING that works with 10V HI and LO input and outputs. What does the WR-CCH connect to: Use the cables we included and connect them between the DB25 connectors on the WR-CCH and any (2) COM ports on your computer. COM ports on computers are always MALE (you can see the pins) We've included 1ft 25-9 adapter cables if you have 9-pin COM ports. What does each COM port do: Each COM port gives you (3) CHANNELS. The COM port connected to the left controls the 3 left channels. The COM port connected to the right controls the 3 right channels. What is a CHANNEL: A CHANNEL consists of an INPUT, an OUTPUT, and GROUND. They are marked "I" for INPUT, "O" for OUTPUT, and "G" for GROUND. Depending on the COM port used, CHANNELS have names: PORT/ADDRESS CHANNEL NAMES COM 1 3f8 1A 1B 1C COM 2 2f8 2A 2B 2C COM 3 3e8 3A 3B 3C COM 4 2e8 4A 4B 4C COM 5 2a0 5A 5B 5C COM 6 2a8 6A 6B 6C COM 7 2b0 7A 7B 7C COM 8 1b8 8A 8B 8C COM 9 1a0 9A 9B 9C COM 10 1a8 10A 10B 10C COM 11 1b0 11A 11B 11C COM 12 1b8 12A 12B 12C Thus, if you connect the left side of the WR-CCH to COM1, the three left channels are 1A, 1B, and 1C. If you connect the right side of the WR-CCH to COM 12, then the right three channels would be 12A, 12B, 12C etc. Take whatever port you connect a side to, use the above chart, name your channels left to right, A,B,C with the port # in front of it. MAKE SURE YOU LABEL WHICH COM PORT YOU CONNECT TO AND THE RESULTING CHANNEL NAMES WE'VE INCLUDED LABELS FOR YOU TO DO THIS TECHDOCS\INSTALL\WR-CCH.INS 7/94 1 of 4 Electrically speaking: The WR-CCH is breaking out the lines of COM ports to create inputs and outputs. COM ports outputs are generally driven HI or LO 10 Volts. Thus when CartReady makes a channel go HI or LO, we are energizing the corresponding channel output + or - 10V. Channel OUTPUT: If the WRCCH connects to COM2 for example, and CartReady tells 2B to go HI, you will observe the 2B channel output go HI. Many electrical devices such as relays, switchers, and other devices can be controlled with HI and LO control. The COM port output can sink or drive up to 20ma of current and is limiting. Channel INPUT: When you connect something to an INPUT, CartReady can detect when the channel goes HI or LO. Anything ABOVE 3 volts is considered HI Anything 0 or below is considered LO RS-232 Experts Only (who want to know): If you talk "RS-232" A, B, C outputs are TD, RTS, DTR respectively A, B, C inputs are CTS, DSR, CD respectively LEDS: The WR-CCH has built in LED monitors that tell you the status of all lines. GREEN is HI and RED is LO One row marked "O" is monitoring the respective OUTPUTs One row marked "I" is monitoring the respective INPUTs Connect to COM Connect to COM ^ ^ 旼컴컴컴컴컴컴컴컴� 旼컴컴컴컴컴컴컴컴� � RS-232 DB25 � � RS-232 DB25 � 旼컴컨 좔컴컴컴컴컴컴컨 좔컴� � 旼� 旼� 旼� 旼� 旼� 旼� � � 쿚� 쿚� 쿚� 쿚� 쿚� 쿚� � � 읕� 읕� 읕� 읕� 읕� 읕� � � 旼� 旼� 旼� 旼� 旼� 旼� � � 쿔� 쿔� 쿔� 쿔� 쿔� 쿔� � � 읕� 읕� 읕� 읕� 읕� 읕� � � WRCCH � 읕컫컴컴컫컴컫컴컴컫컴컫컴컴컫컴컫컴컴컫컴컫컴컴컫컴컫컴컴컫� 픏-G-I� 픏-G-I� 픏-G-I� 픏-G-I� 픏-G-I� 픏-G-I� (captive barrier connects) 5.25"w x 3.25"d x 1"h 旼� I = Input � � indicates an LED for the indicated line O = Output 읕� TECHDOCS\INSTALL\WR-CCH.INS 7/94 2 of 4 CHANNEL COMMANDS in the CartReady Playlist screens: LATCH CHANNEL xx HI/LO This command makes any channel (xx) HI or LO. Thus if you say LATCH CHANNEL 2B HI, then 2B will go HI The channel stays HI forever, until you LATCH it LO again For example RAMKO Research makes a logic controlled relay It's called the PL/ARC and costs less than $50. (Those who are handy can make their own relay devices, (just make sure you don't sink more than 20ma off the WRCCH. Many switchers are controlled by making lines go HI and LO. WAIT FOR CHANNEL xx HI/LO This command makes the Playlist wait for channel (xx) to go HI or LO Say WAIT FOR CHANNEL 2B HI, and we wait for 2B to go HI (the playlist waits at that sequence until the statement becomes true) Note: WAIT FOR CHANNEL supports TIME WINDOWS where you can also say NOT BEFORE hh:mm:ss and IF AFTER hh:mm:ss GOTO xx where xx is a sequence below, i.e jumping to another sequence. WAIT FOR CLOSURE on xx This command is used to detect closures When you say WAIT FOR CLOSURE on 2B, CartReady instantly makes the output go HI and waits for input to go HI on that channel Channel 2B 旼왯커旼� 쿚납G납I� 읕牡켸읕� � � 읕 R 켸 When the Relay (R) closes, it ties the INPUT to the OUTPUT Since we're making the OUTPUT HI, the INPUT will go HI too. This is how we detect closures! The WAIT FOR CLOSURE also supports TIME WINDOWS This works for push button controls used for live-assist. Turn Network ON/OFF using channel xx This command is just like LATCH CHANNEL where ON is HI and OFF is LO We sell an audio on/off switch called the WR-CCA that works under this control. It also provides for 100ms ramping. Many other off-the-shelf devices work the same way. We created the command to make the playlists more readable. 旼컴컴� 旼컴컴컴컴컴커 WR-CCH 쿚UPUT� -----> 쿥RCCA INPUT � 읕컴컴� 읕컴컴컴컴컴켸 TECHDOCS\INSTALL\WR-CCH.INS 7/94 3 of 4 EXAMPLE OF WRCCH 컴컴컴컴컴� Computer � � PC COM 2 쳐컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커 � � PC COM 1 쳐컴컴컴컴커 � 컴컴컴컴컴� � � � � 旼컴컴컴컴컴컴컴컴� 旼컴컴컴컴컴컴컴컴� � RS-232 DB25 � � RS-232 DB25 � 旼컴컨 좔컴컴컴컴컴컴컨 좔컴� � � � "COM1" "COM2" � � � � 旼� 旼� 旼� 旼� 旼� 旼� � � 쿚� 쿚� 쿚� 쿚� 쿚� 쿚� � � 읕� 읕� 읕� 읕� 읕� 읕� � � 旼� 旼� 旼� 旼� 旼� 旼� � � 쿔� 쿔� 쿔� 쿔� 쿔� 쿔� � � 읕� 읕� 읕� 읕� 읕� 읕� � � WRCCH � � � � "1A" "1B" "1C" "2A" "2B" "2C" � 읕컫컴컴컫컴컫컴컴컫컴컫컴컴컫컴컫컴컴컫컴컫컴컴컫컴컫컴컴컫� 픏-G-I� 픏-G-I� 픏-G-I� 픏-G-I� 픏-G-I� 픏-G-I� � � � � � � � � � � � � � � � � � � � � � � � � � � �<�<� � �<�<� � �<�<� � 旼� � 旼� � � � � �>컴>� � �>컴>� � �>컴�>� � 旼컴� � 旼컴� � � Clos A.

When 1A goes HI, the network audio is turned on. When 1A goes LO, the network is turned off. Many off the shelf relays and switches work in this same fashion. In CartReady, you use either the LATCH 1A HI or TURN NETWORK ON USING 1A commands. The other five channels on the WR-CCH are being used to detect closures. These could be satellite network relays, momentary push buttons, or any thing that gives you momentary closure. In CartReady, you use the WAIT FOR CLOSURE ON 2A (any channel etc.) CartReady makes the OUTPUT go HI and waits for the INPUT to go HI since the INPUT will go HI anytime the relay closes. (assuming you connect the OUTPUT and INPUT to each side of the relay/push button contacts.) TECHDOCS\INSTALL\WR-CCH.INS 7/94 4 of 4
