Terminal Port
Characteristics of the terminal port
General
The following table describes the characteristics of the terminal port:
Structure
Physical interface
Transmission
Protocol
UNI-TELWAY mode (master or slave)
non-isolated RS 485
Master/slave multidrop
Binary rate
Character Mode
non-isolated RS 485
19,200 bits/s by default, modifiable from
1,200 to 19,200 bits/s (1 start bit; 8 data bits; even, odd or no parity; 1 stop bit).
No protocol
9,600 bits/s by default, modifiable from 1,200 to 19,200 bits/s (7 or 8 data bits; even, odd or no parity; with or without echo).
Configuration Number of devices Maximum eight (eight addresses managed by the master). In slave mode, addresses 4,
5, 6 are selected by default. In master mode, the reserved addresses are: l l
1, 2 and 3 for the programming terminal
4 and 5 if a CCX 17 is present
The other addresses are available.
Utilities
Length
UNI-TE
10 meters maximum
One (point to point) device
10 meters maximum
Point to point requests with maximum 128byte reports at the initiative of every connected device. There is no broadcast at the initiative of the master.
Maximum 120-byte character string. Messages must end with
$0D (carriage return).
Other functions Transparent communication between all devices within a network architecture via the master.

Safety
Monitoring
A control character on each frame, acknowledgement and possible repetition.
Table indicating bus state, device states and error counters accessible on slaves
No error reported.
No flow control.
Note: Using a TSX P ACC 01 (See
TSX P ACC 01 device, p. 47) connection
device means the RS 485 link can be used in isolated mode.
Note: We strongly recommend that, after use, you do not leave a TSX PCU 103• or TSX PCX 1031 cable connected to the Uni-telway bus at one end and unconnected at the other.

Terminal Port
Terminal port connector pin configuration
General
The terminal port connectors marked TER and AUX are 8-pin mini-DIN which can be locked.
The signals are given below:
TSX DM 57 xx
1 D (B)
2 D (A)
3 not connected
4 /DE
5 /DTP (1 = master)
6 not connected
7 0 volt
8 5 volts
1 D (B)
2 D (A)
3 not connected
4 /DE
5 /DTP (1 = master)
6 not connected
7 0 volt
8 not connected l l
Note: The operation of the terminal port depends on two parameters:
Signal status/DTP (0 or 1), fixed by cabling accessory (TSX P ACC 01 cable).
Software configuration of the terminal port defined in PL7.
The table below defines the functioning mode of the terminal port according to these two parameters:
PL7 configuration Signal /DTP = 0
Master UNI-
TELWAY
Terminal port in UNI-TELWAY slave mode (default)
Slave UNI-
TELWAY
Character mode
Terminal port in UNI-TELWAY slave mode
Signal /DTP = 1
Terminal port in UNI-TELWAY master mode
Terminal port in UNI-TELWAY master mode (default)
Terminal port in character mode Terminal port in UNI-TELWAY master mode (default)
