503108 RS-232 INTERFACE
S1-3 on = send switch changes as “X”
messages as other controllers
alter router
S1-3 off = only respond to inquiries from
host
The 503108 is shipped with S1-3 in the on position.
S1-4 on = send XON / XOFF to host if
buffer fills
S1-4 off = do not send XON / XOFF
The 503108 is shipped with S1-4 in the on position.
S1-5 on = host mode
S1-5 off = terminal mode
The 503108 is shipped with S1-5 in the on position.
An 8 position DIP switch inside the module (S2)
sets the system size.
S2-1,2,3 Levels
1 Level =1 off
2 off 3 off
2 Levels = 1 on 2 off 3 off
3 Levels = 1 off 2 on 3 off
4 Levels = 1 on 2 on 3 off
5 Levels = 1 off 2 off 3 on
6 Levels = 1 on 2 off 3 on
7 Levels = 1 off 2 on 3 on
8 Levels = 1 on 2 on 3 on
S2-4,5,6 Number of outputs
8 Outputs =
4 off 5 off 6 off
16 Outputs = 4 on 5 off 6 off
24 Outputs = 4 off 5 on 6 off
32 Outputs = 4 on 5 on 6 off
40 Outputs = 4 off 5 off 6 on
48 Outputs = 4 on 5 off 6 on
56 Outputs = 4 off 5 on 6 on
64 Outputs = 4 on 5 on 6 on
S2-4,5,6 are not used on 12 input systems
S2-7 on = 12 input systems
S2-7 off = 8 or 16 inputs
S2-8 must be off off for 12 input systems
S2-8 off = 8 inputs
S2-8 on = 16 inputs
INSTALLATION
The RS-232 serial control option is normally
installed at the factory. If the 503108 module is
ordered separately, it should be plugged into the
left-most position in the router frame. In multi-frame
systems, the 503108 can be installed in any frame.
Serial connections. Connection is via a 9 pin
female D connector on the rear of the frame. The
pin connections for this connector are as follows:
Pin 1 Ground
Pin 2 Transmit - output (to receive - input)
Pin 3 Receive + input (to transmit + output)
Pin 4 Ground
Pin 5 No connection
Pin 6 Ground
Pin 7 Transmit + output (to receive + input)
Pin 8 Receive - input (to transmit - output)
Pin 9 Ground
When used for RS-232C control, pins 3 and 7 are
not connected.
The 503108 is normally configured at the factory
for RS-232 interface. RS-232 is also available. It
is possible to change from RS-232 to RS-422 (or
RS-422 to RS-232) in the field. Refer to the circuit
description for additional details and contact SVS
to obtain the required parts.
The 503108 has two DIP switches. A 5 position
DIP switch on the front edge of the module (S1)
sets the data rate and communication mode. The
settings for S1 are as follows:
S1-1,2 communication speed
1.2K Baud =
1 off 2 off
9.6K Baud = 1 on 2 off
38.4K Baud = 1 off 2 on
115.2K Baud = 1 on 2 on
The 503108 is shipped set to 9600 baud.
