RS-485
This section applies only if you are configuring Port 1:
1.
With
rS485
displayed, press the
key.
Adr XX
is displayed. This is the slave address of the indicator.
2.
Press the
ENTER
key to accept the displayed address or key in a new value
then press
ENTER
.
RS-485 mode is very similar to SMA mode, but the transmission is over
an RS-485 multidrop connection instead of over RS-232 hardware.
There is a slight difference in the protocol as well. The master must send
the slave address as part of the request. For example, instead of
sending:
<LF>W<CR> to the indicator,
<LF><sadd>W<CR> must be sent.
<sadd> is the slave address of the indicator that the master wants a
response from. If the slave address sent to an indicator matches the
configured slave address, the indicator will respond with the slave
address as part of the response. All SMA responses begin with a <LF>.
The slave address will be the character immediately following the <LF>.
485Hd
This section applies only if you are configuring Port 1.
1.
With
485 Hd
displayed, press the
key.
Adr XX
is diplayed. This is the slave address of the indicator
2.
Press the
ENTER
key to accept the displayed address or key in a new value
then press
ENTER
.
485 Hd mode is essentially the same as RS-485 mode, but the
transmission is over a Half-Duplex (2-wire connection) instead of the
Full-Duplex connection that must be in place for RS-485 mode. The
protocol is exactly the same a RS-485 mode (the slave address is sent
with the commands and responses). See the RS-485 description
(above) for complete details.
RS485Hd wiring:
4 wire RS485 to 2 wire RS485
Jumper TXA to RXA and TXB to RXB. The indicator will adjust for the serial loop back
when RS485 Half duplex is selected.
TXA

to A or +
TXB
