The BBC Goertz Metrawatt M2110 is a historic (about 1984) 30000 count bench multimeter with RS232 connectivity.
Hardware
RS232 Interface:
- 150/300/600/1200/2400/4800/9600 baud, configurable via rotary switch
- 7 data bits
- No/even/odd parity, configurable via DIP switches
- 1 or 2 stop bits, configurable via DIP switch
- Optional CTS handshake, configurable via DIP switch
- Output intervals 0,66s/10s/1m/10m/1h/manual/remote controlled, configurable via rotary switch
- Manual output sends value on button Start/Reset pressed.
- Remote controlled output sends data on CTS set or ENQ sent, configurable via DIP switches
- Max. 1,5 measurements/s.
RS232 cable:
- 25 pin "female" connector
- Null modem cable required (DTE configuration)!
