6100 MPS-B Programming Manual

INTRODUCTION TO 6100 MPS-B
Line Configuration Options
MPSBPACE (1 word) specifies the maximum number of consecutive
WRITE requests that can be performed by MPS-B before all stations
are polled again.
The value can range from 0 through 32767. The default value
is zero (only one I/O request permitted at any given time).
If the value specified for MPSBPACE is zero, a HALT POLL request
(when stations are polled) must be issued prior to any WRITE
request.
MPSBBAUDnnnnn (1 word) specifies the transmission speed in bits
per second. The value nnnnn may be one of the following: 50, 75,
110, 134, 150, 200, 300, 600, 1200, 1800, 2000, 2400, 3600, 4800,
7200, 9600, or 19200.
MPSBBAUD1200 is the defaulted value.
MPSBASYNC (1 byte) specifies asynchronous operation. The value
specified must be zero. Asynchronous operation is the default.
MPSBSYNC (1 byte) specifies the number of leading synchronization
characters (SYN) inserted on transmit.
The value can range from 1 through 255 and should range from 2
through 255 (at least two SYN characters are recommended).
MPSBCHARACTERSIZE (1 byte) specifies the number of bits that make
up a character during transmission.
The value can range from 0 through 8. If the value specified for
MPSBCHARACTERSIZE is zero, the character size is 7 bits.
It is recommended that the character size for ODD or EVEN parity
(see MPSBODD and MPSBEVEN, below) should be 7 and the character
size for no parity (see MPSBNONE, below) should be 8.
MPSBODD (1 byte) specifies that ODD parity is generated for
transmitted data and checked for received data. The value must
be zero.
MPSBEVEN (1 byte) specifies that EVEN parity is generated for
transmitted data and checked for received data. The value must
be 1. This is the default.
