Auxiliary Port

Baud Rate, Parity, Stop Bits, Data Bits

Set communications parameters for the aux port.

Example:

To change Data Bits to Eight, ensure that default parameters

remain the same, enter

51<Kp,,,1>CR

or

51<Kp2,1,0,1>CR

.

Aux Mode

Toggle between aux port and host.
Format: 51<

Example:

To enable Aux Port, enter

51<K01>CR

.

Host Protocol Commands

Note:

Changes made in the concentrator to communications parameters such

as baud rate, parity, stop bits, LRC, etc., must be matched in the host or com-
munications will be lost. If this occurs, default the concentrator (see
Appendix C — “Defaulting the MS-5000” on page A-6).

If selecting one of the options from 0 to 4 (Point-to-Point, Point-to-Point with
RTS/CTS, Point-to-Point with XON/XOFF, Point-to-Point with XON/XOFF
and RTS/CTS, or Polling Mode D), use this format:

Host Protocol:

Set host protocol and related parameters.
Format: 51<Kf

protocol

>CR

Example:

To change the Protocol to Polling Mode D, enter

51<Kf4>CR

.

If selecting Multidrop (5), you must define an address and add it to the for-
mat (data B).

baud rate:

0 = 2400

3 = 9600

2 = 4800 4 = 19.2K

parity:

0 = None

1 = Even

2 = Odd

stop bits:

0 = One

1 = Two

data bits:

0 = Seven

1 = Eight

0 = Disable
1 = Enable

0 = Point-to-Point

1 = Point-to-Point with RTS/CTS
2 = Point-to-Point with XON/XOFF
3 = Point-to-Point with RTS/CTS & XON/XOFF

4 = Polling Mode D
5 = Multidrop (requires address)
6 = User Defined
7 = User Defined Multidrop
