TCS RS232 Control Functions
TCS RS232 Control Codes
TCS utilizes RS232 communication channel to communicate with PC and other Tact
units. To send data or commands to TCS, PC software sends variable length data packet.
Each packet consists of N bytes. Packets are structured in the following way:
Byte #0 = N - number of bytes in the packet
Byte #1 = A0 - Least significant address byte
Byte #2 = A1 - Most significant address byte
Byte #3 = CC - Command code byte
Byte #4 = D0 - First data byte
Byte #5 = D1 – Second data byte
….
Byte #(N-1) = Last data byte
All Tact components connected to the PC will receive transmitted packed. The only
component that will respond to the received message is the one that matches its internal
address with the received one. All others will ignore entire packet. Addressed component
could respond by sending a packet of its own to acknowledge received packet, or send
back requested information, or not to respond at all depending on the received command
code.
The following is a description of TCS codes used to control basic functions of TCS
preamplifier. These codes can be supplied to custom installers to link Tact products to
RS232 remote controls.
