WaveWare TMR1P - Manual (Page 4)

DAVISCOMMS (S) PTE LTD
When a port control code sent is “0”, the corresponding port is set to low state or sink state.
When a port control code sent is “k”, the corresponding port’s state remains unchanged from its
previous state (“k” means “keep”).
When a port control code sent is “s”, the corresponding port is set to a state which is the opposite
of the previous state (“s” means “toggle”).
When a port control code sent is “r”, the corresponding port is reset to high impedance state (“r”
means “reset”). All 8 ports can also be reset to high impedance if the reset control code “r” is sent
(refer to MESSAGE PROTOCOL section), or if the device is programmed with the TPS.
When the TMR1P is switched off and on again, the states of all the 8 output ports will
remain unchanged.
For numeric vector, the control code supported is either “0” or “1”, control code “k”, “s”
and “r” are not supported.
1.6
Output Display Message
The TMR1P is able to receive numeric and alphanumeric messages and send via the RS232 serial
output to any industrial standard display device. The message buffer size is 10,240 bytes and the
maximum message length is 4096 bytes. For continuous receiving, it can receive messages of
1000 characters. The RS232 port speed of 1200/2400/4800/9600/19200 baud rate with
even/odd/none parity option can be set through the TPS.
1.7 Error Message
When the TMR1P detects any errors in a received message, it will discard the message, truncate
the error message, or send the error message as it is without any truncation, depending on the TPS
setting (error message handling option) programmed in the unit.
TPS Option:
Error Message: Send/Truncate/Discard
1.8 Configuring an Output as Source or Sink
Two (2) of the 8 output ports can support up to a maximum of 1A source current at High
state or to sink a maximum of 1A drain current at Low state. The other 6 ports have a
maximum current rating of 100mA for both source and sink (High and Low state).
