BASIC HARDWARE CONNECTIONS
CM9700-CC1 CONNECTION
Use the 16-pin terminal block (included with the CM9700MDD-EVS) for the RS-422 serial connection (Pelco P protocol) between the CM9700MDD-EVS and the CM9700-CC1.
Figure 12 shows how to wire the terminal block and connect it to the CM9700MDD-EVS. Note that the terminal block can be attached to the CM9700MDD-EVS only in the proper position, as shown in Figure 12.
NOTE: When connecting peripheral equipment to the CM9700-CC1 serial communication ports, shielded cabling is required to comply with CE emissions guidelines.
Figure 12. Wiring the CM9700MDD-EVS Terminal Block
1.Prepare a Cat5e or better cable (user-supplied) with an RJ-45 connector at one end and with the individual wires exposed at the other end.
2.Connect the cable’s individual wires to the terminal block on the rear panel of the CM9700MDD-EVS. An arrow on the rear panel identifies pin 1; on the terminal block, pin 1 is the leftmost lead on the top row and pin 9 is the leftmost lead on the bottom row (refer to Figure 12). Use a small screwdriver to open the clamp for a particular lead.
Figure 13 on page 17 and Table A identify the RS-422 pin assignments on the CM9700MDD-EVS and the CM9700-CC1.
3.Insert the cable’s RJ-45 connector into any available RS-422 COM port on the CM9700-CC1. Remember that the first few RS-422 COM ports on the CC1 must be used for one or more matrix bays and any network interface units and hot switch units. For more information on using RS-422 COM ports, refer to the matrix system port assignment table and the Installation/Operation manual for your specific matrix system.
