The colors are for the Maxc2adapter cable. Groups of wires separated by horizontal lines indicate the cable pairing. The colors areonly intended as a suggestion. Note that pins 16 and 35 of the DCC-37P are used twice. (This cable isused between Maxc2 and the IMP).DCC-37P DBC-25PWireSignal name1 jump to 2TYIB' - 2.4v205RedTYIB2118WhiteGND3 jump to 4FRNHB' - 2.4v227GreenRFNHB2320BrownGND5 jump to 6LIB' - 2.4v241YellowLIB2514BrownGND7 jump to 8IData' - 2.4v263OrangeIData2716BrownGND288RedHData1021BrownGND306VioletLHB2919WhiteGND312BlueRFNIB1315WhiteGND334GreenTYHB3217WhiteGND1511GreenIRT1624BlackGND3412RedIMR1625BlackGND189YellowHRT3522BlackGND3710BlueHMR3523BlackGNDNfq bpX( ^q1 Zh Xi Wg U Q QW Q QW Q QWQQWyKQKQWQQWQQW}Q}QWXQWK Q QW?Q?QW&Q&QW$Q$QWyQQWMQMQWQQWQW )Q)QWa+AQ+AQWc+Q+QW,(Q,(QW,QW34Q4QW4Q4QWc5*Q5*QW5Q5QW6Q6QW7FQ7FQWc7Q7QWX8Q8QW8Q8QW9mQ9mQW*:Q:QW P 4 M )4 K{ KC gK{ gKC KC  K{ KCK{KCKC`)K{)KCa+AK{+AKC,K{,KCc,kK{,kKCo,K{,KC-KC4K{4KC*5*K{5*KC#6MK{6MKC I 4 F )4 Eg E/ gEg gE/ E/  Eg E/EgE/E/`)Eg)E/*Eg*E/+KEg+KE/,Eg,E/-Eg-E/-E/54Eg4E/*5*Eg5*E/#6MEg6ME/ C 4 @ )4 ?S ? g?S g? ?  ?S ??S??`)?S)?*?S*?+K?S+K?,?S,?-?S-?-?54?S4?*5*?S5*?#6M?S6M? = 4 : )4 9? 9 g9? g9 9  9? 99?99`)9?)9*9?*9+K9?+K9,9?,9-9?-9-9549?49*5*9?5*9#6M9?6M9 7 )4 65 5 g65 g5 5  65 56555`)65)5*65*5+K65+K5,65,5-65-5-5546545*5*655*5#6M656M5 4 )4 3+ 2 g3+ g2 2  3+ 23+22`)3+)2a+A3++A2,3+,2c,k3+,k2o,3+,2-243+42*5*3+5*2#6M3+6M2 1 )4 0! / g0! g/ /  0! /0!//`)0!)/a+A0!+A/,0!,/c,k0!,k/o,0!,/-/40!4/*5*0!5*/#6M0!6M/ . )4 - , g- g, ,  - ,-,,`)-),a+A-+A,,-,,c,k-,k,o,-,,-,4-4,*5*-5*,#6M-6M, + )4 * ) g* g) )  *  )* ))`)* ))** *)c+** +*)+* +),j* ,j)-%)4* 4)*5** 5*)#6M* 6M) ( )4 ' & g' g& &  ' &'&&`)')&*'*&c+*'+*&+'+&,j',j&-%&4'4&*5*'5*&#6M'6M& %~ )4 # # g# g# #  # ####`)#)#*#*#c+*#+*#+#+#,j#,j#-%#4#4#*5*#5*##6M#6M# "t )4  g g        `) ) * * c+* +* + + ,j ,j -% 4 4 *5* 5* #6M 6M J #<7L6Alto - 1822 Interface Distant host test plugThis plug loops back the Alto-1822 interface using 'Distant-Host' signalsPlug type DCC-37POn the DCC-37P connector Jumper pinsTYIB'1to14TYHB'TYIB20to33TYHBRFNHB'3to12RFNIB'RFNHB22to31RFNIBLIB'5to11LHB'LIB24to30LHBIData'7to9HData'IData26to28HDataIRT15to18HRTIMR34to37HMRAlto - 1822 Interface Local host test plugThis plug loops back the Alto-1822 interface using 'Local-Host' signalsPlug type DCC-37POn the DCC-37P connector Jumper pinsTYIB'1to2+2.4vRFNHB'3to4+2.4vLIB'5to6+2.4vIData'7to8+2.4vTYIB20to33TYHBRFNHB22to31RFNIBLIB24to30LHBIData26to28HDataIRT15to18HRTIMR34to37HMRNfq bpX, _qI \  Y X Y X Y XX Y XoYYYX Y XYXXYXR&>R'%R'%R#(HR(HR(R(R Qg b%5 O b%5 N] b%5 L L ;L ;L ZL ZL L LonLnLLLLpLpL LpLLoLLL bL bL!L!L!Ls%5L%5L &UL&UL'tL'tL(L(Lo(L(L KS b%5 I b%5 Bp* ?qG < 9 9n 9 9n 9 9nX 9 9noY9Y9n 9 9n99nX99n<9<9n:9:9n8989ny99na9a9n99n99nX;9;9n99n99nX9X9n99n99n_9_9no99n99n 9 9nXe9e9n99n99n*99n99n ]9 ]9n 9 9nX!99!99n"9"9nc"c9"c9n#*9#*9n 8! b%5 6 b%5 5 b%5 3 3Z ;3 ;3Z Z3 Z3Z 3 3Zon3n3Z33ZXk3ZU33Zp3Z 33Zo33Z3Z b3 b3Z!3Z#%53%53Za&3&3Z'F3'F3ZW'3'3Z(M3(M3Z 2  b%5 0 b%5 / b%5 -~ -F ;-~ ;-F Z-~ Z-F -~ -Fon-~n-F-F-~-Fp-~p-F -Fp-~-Fo-~-F-F b-~ b-F!-~!-F!-Fs%5-~%5-F &U-~&U-F't-~'t-F(-~(-Fo(-~(-F + b%5 *t b%5l $*RCb71822 Cable Breakout BoxThis is a 122 pin edge-connector wire-wrap board plus several scotchflex to DB-37 adaptors.
