Model E1070 Indicator Service Manual
This section applies only if you are configuring Port 1:
1. With RS485 displayed, press the PRINT 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>.
1. With 485 Hd displayed, press the PRINT 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.
