    1.2 RADIO AND TV INTERFERENCE The Model 1200/1201 generates and uses radio frequency energy, and if not installed and used properly-that is, in strict accordance with the man- ufacturer’s instructions-may cause interference to radio and television reception.

  • Page 4: Ce Notice

    • LEDs monitor data and control signals (Model 1201 only) 2.2 DESCRIPTION Measuring only 5.3 x 2 x 1.2 inches, the Patton Model 1200 is the small- est self-powered synchronous modem eliminator on the market. All power is derived from the RS-232 data signals, so no AC power or bat- teries are required.

  • Page 6: Installation

    1. Configure according to the instructions listed in section 4.0, “Config- uration” on page 7. 2. Turn off the computer or device to which the Model 1200 is to be connected. 3. Plug the DB-25 connectors directly into the serial ports of your RS- 232 devices.

  • Page 7: Configuration

    4.0 CONFIGURATION The Model 1200 is equipped with four strapping options that allow config- uration to a wide range of applications. To gain access to the internal straps, loosen the hex nuts on the DB-25 connectors and pry open the case between the plastic shell ears.

  • Page 8: Rts/Cts Delay

    4.3 RTS/CTS DELAY The RTS/CTS delay straps determine the amount of delay between the time the Model 1200 “sees” RTS and when it sends CTS. In order to emulate either dial-up or leased line modems, you can set this strap at either no delay, 6.6mS or 53mS.

  • Page 9: Operation

    Once you have configured the Model 1200 properly (see section 4.0, “Configuration” on page 7) and plugged it into your equipment, you are ready to operate the unit. After the Model 1200 is properly installed, it should operate transparently—as if it were a standard cable connection.
