8.1
Device Specific Serial Communication Info
The standard PGE500 model provides RS232 / RS485 serial
communications. The following information and the RS485 /
RS232 command protocol summary listed on the next page
should be used to set serial communications with the device.
1)
Default settings are 19200 baud rate, 8 data bits, No Parity,
1 stop bit [Factory default; 19200, 8, N, 1].
2)
The baud rate can be set to different values through the
serial interface command set or the front panel push
buttons.
3)
The parity can be changed only through the serial interface
command set and the number of data bits will change
according to the parity selected.
4)
The stop bit is always 1.
5)
All Responses are 13 characters long.
6)
xx is the address of the device (00 thru FF).
7)
<CR> is a carriage return.
8)
_ is a space.
9)
The 'z' in the set or read trip point commands is a + or -.
The plus is the 'turns on below' point and the minus is the
‘turns off above’ point.
10) All commands sent to the module start with a '#' character,
and all responses from the module start with a '*' character.
11) This protocol was designed to be 100% compatible with the
Granville-Phillips® Mini-Convectron®.
12) A valid address must be used even in RS232 commands
[Factory default = 1].
