1784-PKTX, 1784-PKTXD PKTx Communication Card§  Performs data transmission, management, and local network diagnostics for PLC-5 processors over DH+ networks. The 1784-PKTXD has two ports for DH+ communication. 1770-CD (Belden #9463) • 762 m (2,500 ft) @ 230,400 bit/s
• 1,524 m (5,000 ft) @ 115,200 bit/s
• 3,048 m (10,000 ft) @ 57,600 bit/s
0.8A @ 5V DC
1784-U2DHP USB to Data Highway Plus cable Program PLC-5 or SLC 5/04 processors using a personal computer and RSLogix 5 or 500 Programming Software; lets a DH+ host with RSLinx software communicate directly with DH+ stations USB port on computer to 8-pin mini-DIN connector on controller. • DH+: 57,600; 115,200; 230,400 Powered through USB
1756-DHRIO DH+/RIO Communication Interface Module • Provides gateway functionality between ControlNet, Ethernet, and DH+ networks
• Provides scanner functionality to Universal Remote I/O links adapters
2 ports: DH+ or Universal Remote I/O • For DH+: 57,600, 115,200, or 230,400
• For Universal Remote I/O: 57,600, 115,200, or 230,400
• 710 mA @ 5V DC
• 1.7 mA @ 24V DC
1771-AF Fiber-Optic Converter Module Allows DH+ and Remote I/O signals to travel over fiber-optic cable for routing through electrically noisy environments; converts twinax electrical signals to light (for transmission over fiber-optic cable), and then converts the light back to electrical signals (for transmission on twinax) • Twinax
• Fiber-optic pre-terminated cables, 1771- PT2 (75 m)
57,600 and 115,200 600 mA
