AXB-232++ - Instruction Manual
Reserved Channels
The following table lists the channels reserved on Device 0.
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. 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)).
To enter Master Mode, 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")
AXB-232++ Program Statements (Cont.)
PULSE
Turns on a channel or variable for a certain amount of time. Once the time elapses, the
channel or variable is turned off. The Pulse time remains the same value until it is changed
within the program.
Example:
SET_PULSE_TIME(12)
Sets the current duration of future Pulses to 1.2 seconds.
SEND_COMMAND AXB_232,
command
AXB-232++ interprets
command
.
SEND_LEVEL AXB_232,
level,variable
Places the
variable
into the CREATE_LEVEL variable, if it were defined in the AXB-232++
DEFINE_START section.
SEND_STRING AXB_232,
string
Places the
string
into the CREATE_BUFFER buffer, if you defined the buffer in the AXB-232++
DEFINE_START section. If it were not, this command transmits the
string
out the RS-232 port.
TO
Activates a channel or variable for as long as the corresponding device-channel of its Push
statement is activated. When the device-channel referenced by the Push statement changes
from off to on, the TO starts activating the device-channel or variable in the brackets following
it. When the device-channel of its Push is released, the TO statement stops activating its
device-channel or variable. For this reason, TO must be found only underneath a Push
statement.
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 AXB-232++ generates a PUSH or RELEASE.
Channel 255
Reflects the state of the CTS input. If the AXB-232++ receives a 'CTSPSH' command, it generates PUSHes for
both the Master and the AXB-232++.
