Hardware Connections
 Figure 1: Back of MP36 showing location of I/O Port | MP36, MP36, MP35R Digital signals may be brought in and out of MP36 (or older MP35) or MP36R through the I/O Port on the back of the device. To interface a parallel port or emulator, an STP35B (or older STP35A) must be connected to the I/O Port. IMPORTANT! These are NOT equivalent to straight-through cables. An off-the-shelf DB25 cable will not make the proper connections. |
 Figure 2: MP46 and BN-SMART-IOCBL | MP46 or Smart Center MP46 and Smart Center can connect to a parallel port or emulator through BN-SMART-IOCBL. The connection between BN-SMART-IOCBL and parallel port may be through a CBL110C or any other straight-through cable with appropriately gendered DB-25 connectors at the ends. |
 Figure 3: Location of printer port on Isolated Digital Interface (shown on STP100C-C with MP150, same on STP100D-C with MP160) | MP160 or MP150 Digital signals may be brought into an MP160 (or older MP150) System via an STP100D-C isolated digital interface module (or older STP100C-C).
