CM9760-REL RELAY INTERFACE UNIT

To connect a CM9760-REL relay interface unit to the VMX300(-E), complete the following steps (refer to the CM9760-REL Installation/Operation manual for detailed instructions):

1.Connect the relay unit to the VMX300(-E) as described below for the appropriate communication mode:

Direct serial: Connect an RS-232 to RS-422 adapter to COM 1 or COM 2 on the VMX300(-E) workstation, and then wire the adapter to a wall block (user-supplied), as shown in Figure 37. Using an RS-422 reversed data cable, connect the wall block to the IN port on the CM9760-REL.

Figure 37. CM9760-REL Direct Serial Connection

Internet Protocol: Connect the RS-422 IN port on the relay unit to an RS-422 serial port on a networked device, such as a PelcoNet encoder. If the networked device does not have an RS-422 serial port, use an RS-232 to RS-422 adapter. (Refer to Figure 26 on page 28 for a sample illustration.)

2.(Optional daisy-chaining): If you are connecting multiple relay units in a daisy-chain series, use the data cables provided with the relay units to connect the first unit’s RJ-45 OUT port to the next unit’s RJ-45 IN port.

3.After installing system hardware, complete the following configuration steps:

a.Add the REL driver and the relay interface unit to the VMX300(-E) server configuration. Each unit in a daisy-chain configuration must be added to the VMX300(-E), and then configured with the appropriate settings. Note that the recommended baud rate for communication between VMX300(-E) and the CM9760-REL is 19200. You must set this baud rate on the Communications tab when you configure the CM9760-REL device in the VMX300(-E). (Refer to the VMX300(-E) Server Configuration Manual for instructions.)

b.Change the CM9760-REL settings to the following recommended settings for VMX300(-E) communication: RS-422, 19200 baud, no parity, 8 data bits, 1 stop bit. (Refer to the CM9760-REL Installation/Operation manual for instructions.)
