Pelco Complete Manual for CM9760-KBD - VCR Programming Instructions

NOTE: It is highly recom- mended that VCRC-P ad- dress # 1 (Frame Address 0) be used first, VCRC-P ad- dress # 2 second, and so on, to minimize program- ming confusion.

NOTE: GPIs are pro- grammed using the 9760 System Manager program. See the section on Software Setup–Using the MGR Pro- gram to Configure VCRC-P Operation for introductory instructions. For detailed programming instructions, refer to the Systems Man- ager manual.

NOTE: If you have no more than 11 VCRC-Ps for which you wish to assign ad- dresses or determine GPI ranges, then you can use the instructions with the CM9760-VCRC GPI/VCR control calculator for deter- mining those items for the CM9760-VCRC-P.

SETUP

PRELIMINARY DISCUSSION

The CM9760-VCRC-P enables automatic control (via macro execution) or manual control (from the CM9760-KBD) of seven predefined VCR functions. Each VCRC-P can control up to 64 VCRs.

VCR control is implemented by associating System 9760 GPIs to VCRs. When a GPI is used for VCR control, its first seven auxiliary relays are used to control the seven most common VCR control functions. The seven auxiliary relay numbers and their associated VCR functions are listed below.

2.Stop

Two key setup procedures are required in order to accomplish VCR control from the Sys- tem 9760. The Frame Address Table in Figure 10 can be used as an aid to implement both procedures.

1.The VCRC-P (1 of 39) must be assigned an address that corresponds to a sequential range of 64 GPIs (VCRs).

Use the Frame Address Table to determine the DIP switch settings for assigning an appropriate VCRC-P address setting.

2.GPIs must be programmed in order for the 9760 CPU to communicate with the VCRC-P.

Each physical GPI # corresponds to an individual VCR and its terminal connection point on the VCRC-P. Therefore, 64 GPIs must be programmed in order to control 64 VCRs from one VCRC-P controller.

The physical GPI # is related to the VCRC-P as follows:

•Physical GPI # 1 corresponds to the first VCR control terminal on the VCRC-P that is addressed as controller # 1 (Frame Address # 0). Likewise, physical GPI # 64 corresponds to the 64th control terminal on VCRC-P # 1.

•The next GPI # (the 65th) corresponds to the 1st control terminal on VCRC-P # 2 (Frame Address # 2). This scheme continues until the last GPI is associated with the appropriate control terminal on the last VCRC-P used, which, in this case, would be controller # 39 (Frame Address # 76).

DIP SWITCH SETTINGS

DIP switch settings are illustrated in Figure 10.
