1201 - Dci Setup - NEC 28i System Manual

Description
Use Program 1201 - DCI Setup to set the values of the DCI S-regis-
ters. The S-registers set the RS-232-C communications options. To
set up the S-registers:
In Program 1202, assign the PMS DCI software port number to a
DCI sub-type. Refer to the "Order" option in Program 0005 if you
need to know the software port number of the PMS DCI port.
Go back to this program and change the S-Register parameters for
the sub-type you assigned in Program 1202. (When changing an
S-Register, keep in mind that many DCIs can share the same DCI
sub-type.)
Refer to the following chart for an explanation of the S-registers
important for the PMS DCI port.
DCI S-Registers (Register Type 1)
Register
65 Baud Rate
Sets the baud rate of the
DCI port.
Stop Bit
Sets the number of stop bits
the DCI expects in the data
stream.
Data Bits
Sets the number of data bits
the DCI expects in the data
stream.
Parity
Sets the parity method the
DCI expects in the data
stream.
66 Request to Send (RTS)
Control
Enables (0) or disables (1)
RTS (pin 4) control. If dis-
abled, the DCI holds RTS
on. For PMS, always dis-
able this control (1).
Data Terminal Ready
(DTR) Control
Enables (0) or disables (1)
DTR (pin 20) control. If
disabled, the DCI holds
DTR on. For PMS, always
enable this option (0).
