  • Page 3 17 Diagnostic LEDs Standalone or Rackmount The TC3420 is a multi-poll Ethernet converter designed with a capability for a multicast topology. It converts RS-232, (RS-422, RS-485 or Analog (2- or 4-wire)* ) asynchronous data to TCP/IP packets for multicast transmission between a Master TC3420 and remote TC3420 Slave units over an Ethernet Network, as shown in Figure 1.

  • Page 5 It is on when adequate power is being derived from the power source. "RS-485" LED:* It is on when the TC3420 is set for RS-485. (Internal SW2-8, On) It is off when the TC3420 is set for RS-422. (Internal SW2-8, Off) "Alarm"...
  • Page 6 "MASTER" (Master/Slave) LED: When "On", it indicates the TC3420 is set as Master. When “Off", it indicates the TC3420 is set as a Slave. When "Flashing", it indicates the IP is set to the factory default. Need to power cycle the unit and set the DFLT dip switch back to the up position to make default IP effective.
  • Page 7 1. SRL/TEL*: Set the unit to Serial Tunnel mode (up position.) Set the unit to Telnet Gateway or Reverse Telnet mode (down position.) The changes apply on the next power cycle. *Note: (Telnet is Not used, for future release) 2. MSTR/SLVE: Set the unit as Master (up position) or Slave (down position.) The changes apply on the next power cycle, reset needed.
  • Page 8 For Stand Alone units, connect this port for RS-232 connection. Connect this port for RS-232, RS-422*, RS-485* or Analog* connection. NOTE: For RS-232 connections, use the IN(-) pin for RxD, OUT(-) pin for TxD and G pin for signal ground. Connect this port using a twisted pair Ethernet cable to the local network.
  • Page 9 600mA. Either a power adapter or power card can be utilized to supply the power to the TC3420. The power terminal block connector can be plugged into any power jack on the rear panel. Since each TC3420 unit is equipped with a power redundancy capability, the power LEDs on the front panel will light according to which power jack it is connected to.
  • Page 10 The "DFLT" LED on the front panel will turn on if the saved settings are the same as the default settings. In order to configure the TC3420 that is, set to default, the user needs to use a PC with a web browser installed Furthermore, the PC's IP address must be set within the range of 192.168.254.1 to 192.168.254.254, and with...
  • Page 11 "Settings" page. Slave unit's IP address can be Static or Dynamic. For static IP setting, the IP address should be entered at the "IP address" field on the "Settings" page. Master Example: TC3420: (Master) Slaves Example: TC3420: (Slaves) - 11 -...

  • Page 12: Dynamic Ip (Dhcp)

    Before you turn on the DHCP option, you need to enter the Master’s IP address at the “Remote IP” field on the "Settings" page for the Slave Unit. Example: TC3420: (Slaves) Please do the following after the "Master IP" has been set on the Slave units. 1. Power off the unit.
  • Page 13 DB9 Female or Terminal Block RS-232 Virtual Pin Connections The DB9 or Terminal Block RS-232 pin connections for the Master and Slave units are the same as depicted on the diagrams below. DB9 connector: Pin 3, receives the transmitted data from the user's RS-232 device. Pin 2, transmits the data back to the user's RS-232 device.
  • Page 14 The local RS-485 transceiver will stay in Tx mode until a predetermined period (transition time; generally used by the customer's device) elapses after the last bit is received from the remote unit. The TC3420 automatically adjusts internally for that specific transition time. (See figure 4) Four-wire RS-485 is a full-duplex operation, which means transmit and receive operations function concurrently.
  • Page 15 The pin assignments are illustrated below. Pins IN(-) & IN(+) are inputs and Pins OUT(-) & OUT(+) are outputs. Terminal block connectors are provided on rear panel of the TC3420 for the 2 wire RS-485 signal connections. The pin assignments are illustrated below. Pins OUT(-) & OUT(+) are inputs/outputs.
  • Page 16 The ground connector should connect to the user's device's signal ground. For an RS-485 application, the transition time is set automatically by the TC3420 once a baud rate is selected from the pull-down field on figure 16 on page 23. The baud rate is set according to the customer's application needs and the TC3420 will adjust accordingly.
  • Page 17 TC3420 can be used in three different modes (Serial Tunnel, Telnet Gateway* or Reverse Telnet*) depending on the user's application. In this mode, one Master TC3420 and (N) Slave units are used, and all of them are connected to serial RS- 232 devices.
  • Page 18 "DISALM" to the down (on) position.) Start your Web browser. In the Address box, enter the IP address of the TC3420. For example, if the unit is set to default Master, enter: http://192.168.254.123 If the unit is set to default Slave, enter: http://192.168.254.124 Once connected, you should see a dialog box as in figure 10, next page.

    IP Address setting must be the same.) UDP Port Number: Two UDP Ports are used by TC3420 communication. (Note: Master and slaves’ UDP port settings must be the same.) UDP Port Number One: The Master unit uses UDP Port One to transmit (Multicast).
  • Page 23 In Telnet Gateway Mode, the TC3420 will disconnect the link between itself and the remote telnet client if there is no data being send by the TC3420 for 30 seconds or the time specified in the Telnet Timeout field below.
