Base Station to Host Formats

The basic format of a message that is transmitted from Base to Host is fairly simple:

Byte position

Function

Possible values

1

RF Terminal ID

0-9, A-Z, a-z, - =

2+

Data Transmitted

**

Last

Termination of message

CR (ASCII 13)

Typically, the Base Station is sending the “answer” to the hosts “question” - for example, if a Base sent a host message to a terminal #2 that said:

2@1,1,1,ITEM NUMBER + EOT

The RF Terminal would display ITEM NUMBER on line 1, position 1 and accordingly, the operator would then enter an item number by scanning or using the keypad. The RF Terminal transmits the data entered -say it’s 123 - to the Base Station, which in turn transmits the following to the host:

2123+CR

Where 2 is the Terminal ID, 123 is the data and CR is the termination, (the plus sign is not transmitted). Besides data, there are other messages that the Base Station will send to

the Host:

Serial Reply

After a Serial command (@S) has been successfully completed, the Base Station sends to the Host the Terminal ID followed by a CR. Serial commands are typically used for attached serial printers. Serial commands cannot be combined with other commands in a message to the Base Station/Terminal.

Remember, you can only send 231 characters (including the ID + @S + EOT).

SIGN ON

To login to the host computer, the user presses a key on the RF Terminal at power-up to get to the SIGN ON screen. As the user SIGNs ON, the Base Station sends back the following SIGN ON message to the host:

Byte position

DC4 (ASCII 20) if 15 line display

 

 

configured as a 15 line display.

message

 

After a terminal SIGNS ON, the host should be prepared to acknowledge the SIGN ON and give the terminal instructions, such as:

Standby for Assignment, Press ENTER to acknowledge

Nothing to do, Press ENTER and See Supervisor

Pick Item 1234

If there is something for the Terminal to do, the host should send instruction to the terminal (as in “Pick Item 1234” above). If there is nothing to do at the time of SIGN ON, the host should acknowledge the SIGN ON and tell the terminal to Stand By or See Supervisor (see lines 1 and 2 above). You will notice that in lines 1 & 2 above, there is a request for the operator to press the ENTER key. This is required for the message to be
