The Allen-Bradley 1784-PCMC1 module comprises the Allen-Bradley 1784-PCMK card and the 1784-PCM6 cable. The PCMK card and the cable are used to make the communication processor interface module and to allow for Peer-to-Peer communication and the programming of the uploading and the downloading processes. The communication cable connects the 1784-PCMK card to a PC, ensuring continuous communication. The Allen-Bradley communication card permits the connected computer to interface smoothly with the other devices on the Data Highway Plus communication network. The 1784-PCMC1 module supports the DH-485 and the remote I/O networks. Note that the included PCMK card does not come with a termination resistor. Therefore, the users should practice caution when connecting the PCMK card at the end of the DH+ or the DH485 link.
