    ASYNC 232↔422/530 CARD 2. Introduction The Async 232↔422/530 Card is a dual rack card incorporating two converters. The converters let computers, terminals, and modems using the RS-232 interface communicate with devices using RS-422 balanced electrical signals. Both units operate full duplex at data rates to 19.2 Kbps over 2 twisted pairs.
  • Page 8: Configuration

    CHAPTER 3: Configuration 3. Configuration This section describes the location and orientation of the Async 232↔422/530 Card’s configuration jumpers, provides detailed instructions on setting each jumper, and describes the settings for each of the rear connection cards. The Async 232↔422/530 Card uses two jumpers that allow configuration to a wide range of asynchronous applications.
  • Page 9: Jumper Locations And Orientation

    ASYNC 232↔422/530 CARD 3.1 Jumper Locations and Orientation The configuration jumpers on the Async 232↔422/530 Card and the rear interface card allow you to configure the function of both front-panel “Carrier Detect” LEDs, as well as the rear interface card CD signal. Figure 3-2 shows the orientation of these jumpers.
  • Page 10: Setting The Configuration Straps

    CHAPTER 3: Configuration 3.2 Setting the Configuration Straps The Async 232↔422/530 Card contains two sets of configuration jumpers, which allow you to set the function of both front-panel “Carrier Detect” LEDs and the CD signal exiting the rear interface card in the rack. Since the Async 232↔422/530 Card contains two converters, each unit can be configured separately.

    CHAPTER 3: Configuration DTE as DSR or RI (JB6 and JB7) Because this rear card is designed to function in more applications than the Async 232↔422/530 Card, this jumper must be installed only in one position. Place the jumper across pins 1 and 2 so that the terminal (DTE) sees DSR as high when the rack is powered.

  • Page 16 CHAPTER 3: Configuration Line Shield (JB2 and JB4) This jumper pertains to the line interface. In the connected position, the jumper links RJ-45 pins 2 and 7 to frame ground and the rear panel. These pins can be used as connections for the twisted-pair cable shield. In position 2 and 3, pins 2 and 7 are disconnected from frame ground.
  • Page 17: Installation

    ASYNC 232↔422/530 CARD 4. Installation This chapter describes the functions of the MicroRacks, tells how to install front and rear Async 232↔422/530 Cards in the chassis, and provides diagrams for wiring the interface connections correctly. 4.1 The MicroRack Chassis The MicroRack 16 has sixteen short-range modem card slots, plus its own power supply.
  • Page 18 CHAPTER 4: Installation WARNING! There are no user-serviceable parts in the power-supply section of the MicroRack 16. Voltage setting changes and fuse replacement should only be performed by qualified service personnel. Switching the Power Supply On and Off The power-supply on/off switch is located on the front panel. When the MicroRack is plugged in and switched on, a red front-panel LED will glow.
  • Page 19: Installing The Async 232↔422/530 Card In The Chassis

    ASYNC 232↔422/530 CARD Switching the Power Supply Between 120 and 240 Volts Although the MicroRack 16 is shipped from the factory with a customer- specified power-supply configuration, you can change the configuration yourself. Follow the steps at the top of the next page to switch the configuration of the power supply between 120 and 240 VAC: 1) Remove the front power-supply card and locate the two-position switch near the back of the card.

    CHAPTER 4: Installation 4.3 Wiring Up the Async 232↔422/530 Card Each of the rear interface cards is compatible with the Async 232↔422/530 Card and has four RJ ports. The two upper ports are either RJ-11 or RJ-45 jacks, depending on the card you select. 4.3.1 RS-232 C ONNECTION The RS-232 ports are always the lower ports on the interface card.

    ASYNC 232↔422/530 CARD 4.3.3 P OINT OINT WISTED ONNECTION The six-position RJ-11 and eight-position RJ-45 jack options for the Async 232↔422/530 Card (always the two upper jacks on the rear interface card) are prewired for a standard telco wiring environment. Connection of a 4-wire twisted-pair circuit between two or more Async 232↔422/530 Cards requires a crossover cable.

    ASYNC 232↔422/530 CARD 5. Operation Once you have configured each Async 232↔422/530 Card and connected the cables, you are ready to operate the units. 5.1 LED Status Monitors The Async 232↔422/530 Card features 13 front-panel LEDs that indicate the condition of the modem and communication link. Figure 5-1 shows the positions of the LEDs.
  • Page 24: Power-Up

    CHAPTER 5: Operation • The green “PWR” LED glows when power is being applied to the modem card through its mid-plane chassis connection. • The green “TD” and “RD” LEDs blink to show positive state data activity. The red “TD” and “RD” indicators blink to show negative state data activity.
