60 Medalist Pro Product Manual, Rev. D 9.6.4.2 Mating connectors for "W" and "LW" models The nonshielded cable connector shall be a 68 conductor connector consisting of two rows of 34 male contacts with adjacent contacts 0.050 inches (1.27 mm) apart. Recommended mating flat cable connector part numbers are: Amp Model 786096-7 Female, 68-pin, panel mount Amp Model 786090-7 Female, 68-pin, cable mount Amp Model 749925-5 (0.050 inches (1.27mm, 50 mil) conductor centers, 28 or 30 AWG wire). Use two, 34 conductor, 0.050 inches (1.27 mm, 50 mil) center flat cable with this connector. This type connector can only be used on cable ends. [1] Amp Model 88-5870-294-5 W/O Strain Relief, 0.025 68es (0.68 mm, 25 mil) conductor centers, 30 AWG wire. Use either on cable ends or in cable middle section for daisy-chain installations [1]. Amp Model 1-480420-0 Power connector 4 circuit housing Berg 69307-012 12-position, 2 x 6, 2 mm receptacle housing [1] See Figure 19. The drive device connector is a nonshielded 68 conductor connector consisting of two rows of 34 female pins with adjacent pins 0.050 inches (1.27 mm) apart. The connector is keyed by means of its shape (see Figure 21). 9.6.4.3 Mating connectors for "WC" and "LC" models The nonshielded connector shall be an 80 conductor connector consisting of two rows of 40 contacts with adjacent contacts 0.050 inches (1.27 mm) apart. I/O connection using a cable is not recommended. The length and size of the host equipment DC power carrying conductors from the DC power source to the host equipment 80 pin disk drive interface connector(s) should be strictly designed according to proper power transmission design concepts. No possibility for the equipment user to attach an 80 pin cable/connector should be allowed, since the length of the DC power carrying conductors could not be controlled and therefore could become too long for safe power transmission to the drive. Daisy-chain 80 conductor cables should especially not be allowed, since the power-carrying conductors on the 80 conductor interface were not intended to support a series of drives.
