2 INSTALLATION
2.1 EPROM Installation
The SATEC communication driver is supplied in 32 Kbyte EPROM memory modules. The
version of the driver is marked on the EPROM label by a combination of:
The number of instruments (1-31)
X - XX - R
Reset option
Data set (1, 2)
E
Error reporting option
Before installing the EPROM in the memory module socket, configure the socket for a 32
Kbyte PROM size by setting a configuration jumper in the BASIC module. Refer to the 1771-
DB BASIC Module User's Manual for additional information on EPROM location and the
jumper pin assignments.
2.2 BASIC Module Peripheral Port Configuration
The BASIC module peripheral port must be configured for the appropriate baud rate by setting
a jumper in the BASIC module. You can select the baud rate of 1200, 2400, 4800 or 9600
baud. The baud rate is factory set at 1200 baud.
Refer to the 1771-DB BASIC Module User's Manual for additional information on the jumper
location and pin assignments.
2.3 Powermeters Communications Settings
The Powermeters should be configured properly to operate with the BASIC module. The
Powermeters communications settings must be compatible with the BASIC module port
interface (RS-422/RS-232) and baud rate used.
The Powermeters communications settings are as follows:
•
ASCII 422, or ASCII 232 mode, accordingly to the interface you apply.
•
Software handshake.
•
Baud rate 1200, 2400, 4800 or 9600, accordingly to the baud rate jumper setting.
•
8 bits, no parity.
The Powermeters communication addresses can be selected from 1 up to the maximum
number that the applied version of the driver supports.
Refer to the Powermeter User's Guide for information on how to set communications
parameters in your instruments.
