5 TAGP Communication Protocol

TagMaster Readers can be controlled and monitored using a protocol called TAGP. The TAGP protocol is
human readable and can be used over TCP/IP, RS232 and RS485. A terminal emulation program such as
PuTTY is all that is required to interact with TAGP.
The "TAGP Protocol Specification" [2] can be downloaded from www.tagmaster.com.
Use login name "partner" and password "245ghz".
PuTTY TagMaster Edition can be downloaded from ftp://partner:245ghz@ftp.tagmaster.com.
All TAGP messages start with a 4-character message identifier and ends with a new line character. To
initiate communication with the TAGP server in the reader, a client has to send a HELO message
specifying the required TAGP version. The TAGP server replies with a RPLY message:
HELOTAGP/2
RPLYHELO00
The client can then send commands to the reader. The most important commands are SET, SETS, GET,
and GETS. SET and GET sets and gets the current value of a variable. SETS and GETS sets and gets the
stored value of a variable. The stored value is used to initialize the variable at startup. The following
example shows how to set the LED to green:
SET LED=GREEN
RPLYSET 00
The reader sends events to the client when something happens. The following example shows a TAG
event that is sent when a tag has been read:
