The CN2600 terminal server uses its built-in dual-LAN ports to implement a “redundant COM” mode that keep your applications running smoothly. Dual-LAN Redundancy The CN2600 has two separate LAN ports that can be connected to separate LAN networks. Dual-LAN redundancy involves setting up two separate physical networks to connect the PC host with the CN2600. In this case, the PC host must also be installed with two LAN cards. If one of the networks fails, the PC host will still be able to communicate with your serial devices over the redundant LAN. Redundant COM The “Redundant COM” (patent pending) operation mode can be used to set up a redundant LAN between the CN2600’s COM ports and the host computer. The redundant structure involves using the CN2600’s two LAN ports to set up two independent LANs that connect the CN2600 to the host computer. If either of the two LANs fails, the other LAN will continue transmitting packets between the serial devices and the host, with the data transmitted through the CN2600. One of the biggest advantages of using Moxa’s Redundant COM mode is that the “switching time” is zero. What this means is that if one of the LANs fails, data transmission between the PC host the serial devices will not be interrupted. Dual-host Redundancy The CN2600’s dual LAN cards can also be used to set up “dual-host” redundancy. In this case, both networks (LAN A and LAN B in the figure) are connected to two different hosts. If either of the two hosts shuts down unexpectedly, the other host will continue transmitting packets to (and receiving packets from) the serial devices connected to the CN2600. Dual-AC Model Supported Dual-power redundancy uses two power inputs and redundant internal power supplies to ensure that the CN2600’s console port, serial ports, and LAN ports will be available, even in the event of power circuit failure. • LAN Interface Number of Ports 2 Speed 10/100 Mbps, auto MDI/MDIX Connector(s) 8-pin RJ45 Magnetic Isolation Protection 1.5 KV built-in • Serial Interface Serial Standards CN2610: RS-232CN2650/2650I: RS-232/422/485 Number of Ports 8 or 16 Connector(s) CN2610/2650: 8-pin RJ45CH2650I: DB9 male RS-485 Data Direction Control ADDC® (Automatic Data Direction Control) Console Port Dedicated RS-232 console port on rear panel (8-pin RJ45) ESD Protection 15 KV for all signals Optical Isolation Protection 2 KV (CN2650I) • Serial Communication Parameters Data Bits 5, 6, 7, 8 Stop Bits 1, 1.5, 2 Parity None, Even, Odd, Space, Mark Flow Control RTS/CTS, XON/XOFF Baudrate 50 bps to 921.6 Kbps • Serial Signals RS-232 TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND RS-422 Tx+, Tx-, Rx+, Rx-, GND RS-485-4w Tx+, Tx-, Rx+, Rx-, GND RS-485-2w Data+, Data-, GND • Software Network Protocols ICMP, IP, TCP, UDP, DHCP, BOOTP, Telnet, DNS, SNMP, HTTP, SMTP, ARP, PPPoE, DDNS Security Protocols RADIUS, https, SSH, PAP, CHAP Driver Support Windows Real COM drivers (for Windows 95, 98, ME, NT, 2000, XP, 2003, Vista, XP x64, 2003 x64, Vista x64), Linux Real TTY driver, fixed TTY drivers (for SCO Unix, SCO OpenServer, UnixWare 7, UnixWare 2.1, SVR 4.2, QNX 4.25, QNX 6, Solaris 10, FreeBSD, AIX 5.x, HP-UX 11i) Configuration Options Web Console, Serial Console, Telnet Console, Windows Search Utility Management SNMP MIB-II IP Routing Static, RIP-I, RIP-II • Physical Characteristics Enclosure SECC sheet metal (1 mm), IP30 protection Weight CN2610-8-2AC: 3760 gCN2610-16-2AC: 3810 gCN2650-8: 3740 gCN2650-16: 3790 gCN2650-8-2AC: 3900 gCN2650-16-2AC: 3980 g Dimensions Without ears: 440 x 198 x 45 mm (17.32 x 7.80 x 1.77 in)With ears: 480 x 198 x 45 mm (18.9 x 7.80 x 1.77 in) • Applications Terminal Sessions 8 sessions per port • Environmental Limits Operating Temperature 0 to 55°C (32 to 131°F) Operating Humidity 5 to 95% RH Storage Temperature -20 to 70°C (-4 to 158°F) Surge Protection 15 KV ESD protection embedded • Power Requirements Input Voltage 100 to 240 VAC, 47 to 63 Hz Power Consumption 235 mA @ 100 VAC, 145 mA @ 240 VAC Power Line Protection 1 KV burst (EN61000-4-4: EFT/B), 2 KV surge (EN61000-4-5) • Regulatory Approvals Safety UL (UL60950), TÜV (EN60950) EMC CE (EN55022 Class A, EN55024), FCC Part 15 Subpart B Class A • Warranty Warranty Period 5 years Model No. Description CN2650-16 Dual-LAN terminal server with 16 RS-232/422/485 ports CN2650-8-2AC Dual-LAN, dual-AC-power terminal server with 8 RS-232/422/485 ports CN2650-16-2AC Dual-LAN, dual-AC-power terminal server with 16 RS-232/422/485 ports CN2650I-8 Dual-LAN terminal server with 8 RS-232/422/485 ports and 2 KV optical isolation CN2650I-16 Dual-LAN terminal server with 16 RS-232/422/485 ports and 2 KV optical isolation CN2650I-8-2AC Dual-LAN, dual-AC-power terminal server with 8 RS-232/422/485 ports and 2 KV optical isolation CN2650I-16-2AC Dual-LAN, dual-AC-power terminal server with 16 RS-232/422/485 ports and 2 KV optical isolation CN2610-8 Dual-LAN terminal server with 8 RS-232 ports CN2610-16 Dual-LAN terminal server with 16 RS-232 ports CN2610-8-2AC Dual-LAN, dual-AC-power terminal server with 8 RS-232 ports CN2610-16-2AC Dual-LAN, dual-AC-power terminal server with 16 RS-232 ports CN2650-8 Dual-LAN terminal server with 8 RS-232/422/485 ports
