7.5 Terminal Mode Serial Protocol for Paradise Datacom SSPA
The Teledyne Paradise Datacom Rack Mount SSPA utilizes Terminal Mode Serial Pro-
tocol (TMSP) as a secondary serial protocol for management and control through a re-
mote serial interface.
TMSP allows the user to access internal SSPA functions via a remote ASCII Terminal
or its equivalent (such as HyperTerminal for Windows). TMSP is accomplished through
either the RS-232 or RS-485, half duplex, serial communication link. US ASCII encod-
ed character strings are used to represent commands and data massages.
A remote terminal or controller initiates a communication session and the SSPA Termi-
nal takes action and returns a report of requested status. The SSPA terminal will not
initiate communication and will transmit data only when commanded to do so. Prior to
establishing the session with the SSPA Terminal, this mode must be enabled through
the SSPA front panel menu.
The remote terminal must be configured with serial settings that match the SSPA’s se-
rial port settings. For example, if the SSPA is set at 9600 Baud, the remote terminal
must be also configured as ASCII terminal at 9600 Baud, no parity, 8 bit data with 1
stop bit serial connection. The SSPA will not echo back any incoming characters, so
local echo must be enabled on the remote terminal.
To establish a remote control session with the SSPA terminal, the user must type
“UNIT#XXX” in the terminal window (all letters must be in upper case), where XXX is
the RM SSPA unique network address or the global call address (255). Press the
“Enter” key on remote terminal keyboard.
The SSPA should answer with “Unit#XXX OnLine”, with the first menu screen on the
following lines. After a remote session is successfully established, the unit will stay
connected as long as needed. The session interface mimics the SSPA’s front panel
menu. To help the user navigate through the menu, the help string with the list of ac-
tive keys always follows the menu strings. For example, the last transmission string on
all informative menu screens will be:
“Active Keys:(U)p+Enter;(D)own+Enter;(C)lrearFlt; (M)enu+Enter; (E)nd+Enter”.
Note
: All letters must be in upper case!
To refresh the current screen on the remote terminal, press the “Enter” key. To end a
session, press “E” and the “Enter” key.
Important! If multiple SSPA units are networked on the same serial
link. Do not establish a session with more than one SSPA at a time.
If you do so you will not get any valid answer from any SSPA!
