The IBM 5494 Remote Control Unit provides access to an AS/400 for remote workstation users. This remote attachment allows users in different buildings, cities or even countries to share the resources of an AS/400 system. The 5494 supports attachment of up to 28 twinaxial devices and up to 56 devices with the 5494 Twinaxial Expansion Kit installed. When either the 5494 Ethernet adapter or Token-Ring adapter is installed, the model EXT can support up to 80 devices, of which up to 56 can be twinaxial, while communicating with an AS/400 over an SDLC, Frame Relay, X.21 or X.25 connection. The 5494 can alternately communicate with an AS/400 over a Token-Ring or Ethernet network. With the addition of the Frame-Relay -- Token- Ring bridge feature, non-SNA traffic on the token-ring LAN's can access the rest of the communication network through the 5494.

The LCD has 16 character positions. It is blank and displays a cursor in
| the rightmost position when not in use. When the 5494 operator panel is in use, there will always be a message code (002-01 in the above example) displayed on the left-hand side of the LCD. The message codes are described in "Message Codes" in topic 3.1. When the 5494 is in use, the LCD can also contain, in the data field on the right-hand side of the LCD, a system reference code (SRC) or information as defined by the message code. In the example, the data field contains an SRC.

If an error occurs before or during normal operation, both a message code and an SRC will be displayed on the LCD and an LED will be lit. If more than one error occurs during normal operation, the message codes and SRCs will cycle at 3-second intervals. If the error clears (a link is established after a failure, for example), the message code and SRC will be removed from the LCD by the 5494.

The keys on the keypad allow commands to be entered and sent to the 5494, and include:

REQ Initiates a request function
PF1 Used for special requests
PF2 Used for special requests
Esc Used to cancel a request
Alt Enables the alternate hexadecimal values of keys 4 through 9, to be used with keys PF1, PF2, and Esc for additional special functions. (Ed. Might be the SHFT key)
Enter Signals to the 5494 the end of an input string
Clear  Clears a value being entered and allows you to begin again
0 to 9 Numerics 0 to 9
Alt+4 Hexadecimal A
Alt+5 Hexadecimal B
