Programming

Reserved Channels

The following table lists the channels reserved on Device 0.

Reserved Channels

Channel

Function

 

 

Channel 254

This is only valid within the device and is not sent to the AXlink master. Reflects AXlink

 

status:

 

• When AXlink is active, this channel is on.

 

• When AXlink is inactive, this channel is off.

 

• When this channel changes state, the AXC-232++ generates a PUSH or RELEASE.

 

 

Channel 255

Reflects the state of the CTS input. If the AXC-232++ receives a 'CTSPSH' command,

 

it generates PUSHes for both the AXC-EM and the AXC-232++.

 

 

Axcess Master Mode

When an Axcess device is placed in "Master Mode", the Central Controller’s PROGRAM port is moved to the Axcess device’s RS-232 port.

Press the escape key, then type either MC or MD:

<esc>MC - connects the device in Master Mode

<esc>MD - disconnects the device

where <esc> means "press the Esc key".

Master Mode can be very useful in situations where physical access to the Central Controller’s PROGRAM port is not practical (for example, in installations where the Central Controller is located a long distance from the bus device(s)).
