X8200 Radio Modem

Type:  Modem
Description:  The X8200 Radio Modem transmits and receives half duplex serial data at baud rates of 1.2K to 115.2K by means of a FM Radio Transceiver operating on the UK and European licence-exempt bands and most other worldwide data frequencies. A 4K buffer memory is provided so that data can be passed asynchronously between the host and modem without the need for handshaking. The CTS output signal can be used for flow control in duplex applications. The over air data speed can be configured at either 5 kbps or 10 kbps. The set up menu of the X8200 can be accessed either by a PC running any terminal emulation program like Hyper Terminal in the accessories section or remotely over the radio link. The set up menu is selected either by connecting pin 6 on the 9 way D Connector to 0v or typing $ then ESC directly after the power has been applied. The menu configuration is permanently stored on EEPROM.
