2. Command, Data, Delimiter
Command consists of 2 alphabetical letters, irrespective of upper or lower case. When input-
ting data, input numeric value data following command. When it receives a correct command,
it echoes back 2 letters of command irrespective of data presence or absence. But when a
wrong command is received, TSL-210 outputs "NR". It always conrms echo back and makes
control adjustments so that communication of commands and data are precise. To take out data
from TSL-210, command for take out without data of echo back is prepared. Delimiter can be
set for CR, LF, or CL/LF.(See 9-2-A. Turning ON/Setting RS-232C delimiter)
10-2-D. SIF connector (RS-232C)
TSL-210 supports RS-232C level and TTL level serial communication however, these cannot
be uses at the same time. (These are connected as wired and) If external equipment supports
RS-232C, connect wires as follows:
External equipment TSL-210
Send --- Receive
Receive --- Send
SG --- GND
Shake hand line should be terminated by external equipment.
[ SIF pingassingment ]
1 RDX : TTL input to TSL-210 (receive)
2 TDX : TTL output from TSL-210 (send)
3 GND : GND
4 6.4V : 6.4V output (power supply for control pad)
5 RRDX : RS-232C level input to TSL-210 (receive)
6 RTDX : RS-232C level output from TSL-210 (send)
