    Active Gauge Controller general operating instructions D386-55-880. Gen eral The Edwards Active Gauge Controller (AGC) RS232 option allows the AGC to be interfaced to a micro-computer or data acquisition system via a serial RS232 communications link. The RS232 communications protocol is set up (and monitored) via a menu tree structure. You move through the menu with simple keystroke combinations entered from the front panel.

  • Page 5: In Stal La Tion

    The installation instructions are listed in Section 3 of D386-55-880. The electrical supply and all other connections to the active gauge controller are through the rear panel shown in Figure 1. The RS232 option serial port, internal relay expansion board and gauge channel expansion board are all shown.

  • Page 6: Rs232 Con Nec Tions

    Connection to the RS232 port is through a 9-way female D-type socket fitted on the rear panel of the AGC. If an IBM compatible computer is to be used then an Edwards RS232 cable may be used to connect the AGC to the computer (refer to section 7.1).

    Con nec tion to an IBM com pati ble com puter Figure 3 shows how to connect the active gauge controller to an IBM compatible computer. Figure 3 - AGC/IBM computer interface Hard ware con trol sig nals If speed of transmission or slow response time for the external equipment cause communication problems, use the two hardware control signals CTS and DTR in addition to the three wire system described above.

    OP ERA TION Gen eral It is important that you read these instructions in conjunction with the active gauge controller general instructions D386-55-880. RS232 se rial com mu ni ca tions The active gauge controller RS232 option is supplied with an RS232 serial communications port to allow interfacing with other equipment.

    Selecting PROTCL allows access sequentially to the BAUD, PAR and STOP sub menus. Note that the number of data bits is fixed at 8. Select PROTCL and press ENTER, the display reads BAUD X where X is a number 1-8 corresponding to the current baud rate setting as follows: Baud Rate 1200 2400 4800 9600 19200 Press ENTER, to retain the setting, this moves to the second sub menu...
  • Page 10 When in printer mode, gauge information is automatically transmitted at an interval set in the RATE menu. This information may be be printed out on a serial printer, or logged directly onto a computer for storage and analysis. The information consists of a block of data divided into lines (one for each gauge channel in use).

    AGC Re plies to que ries and com mands When a query or command is received by the AGC, a reply is always returned on the serial link. The replies sent by the AGC are text messages - sequences of ASCII coded characters terminated by two control characters CR, LF (ASCII chars 13, 10).
  • Page 13 Prob lem: Non- functional Printer mode Check the printer itself (on-line, paper). Check the connecting lead. Check the hardware control signals (if used). Check correct programming of AGC (COMMS menu) i.e. system is in Printer mode, baud rate, parity, stop bits and cycle rate are programmed as required. If double line spacing appears on printout, disable printer feature which adds an LF every time it gets a CR, as this is transmitted by the AGC.

    AP PEN DIX G AGC RS232 tim ings The AGC transmits serial data via the RS232 in blocks with each block of data consisting of up to 40 bytes and terminated with the CR LF ASCII characters. The time interval between the AGC receiving a message and responding to it will vary due to higher priority routines running in the AGC program.
