<h1>Acromag IP520 Module Support</h1>
<h2>Introduction</h2>
<p>This is a driver for the Acromag IP520 EIA/TIA-232E Industry Pack
communication module (the companion 422/485 IP521 board is not yet
supported).</p>
<p>The driver uses <a href="drvIpac.html">drvIpac</a> for configuration of the
carrier board plus access routines for the underlying ST16C554/654 octalUart
used in the IP modules. The driver implements a standard VxWorks terminal
port making use of the vxWorks tyLib system library.</p>
<h2>Configuration Example</h2>
<p>The following is an example of a startup script (st.cmd) segment that
creates and configures IP carriers, IP520 modules, and tty devices. This
example is compatible with both vxWorks and iocsh startup scripts.</p>
<blockquote>
<pre># Initialize the drvIpac carriers.
# -------------------------------
# carrier#0
ipacAddMVME162 "A:m=0xe0000000,64 l=3,2"
# carrier#1
ipacAddVIPC616_01 "0x6400,0xB0000000"
# carrier#2
ipacAddTVME200 "602fb00"
# Allocate the number of IP520 modules to support.
# ----------------------------------------------------
IP520Drv 6
# Initialize IP520 modules.
# ----------------------------
# IP520ModuleInit(char *moduleID, char *ModuleType, int irq_num,
# char *carrier#, int slot#)
# moduleID - assign the IP module a name for future reference.
# ModuleType - "232", (the IP521 EIA/TIA-422B module is not yet supported).
# irq_num - interrupt request number.
# carrier# - carrier# assigned from the ipacAdd<i>CarrierType</i>() call.
# slot# - slot number on carrier; slot[A,B,C,D] -> slot#[0,1,2,3].
# Init two IP520 modules from the MVME162 carrier; the 1st module is in
# slot A, the second module is in slot B.
IP520ModuleInit "Mod0", "232", 0x80, 0, 0
IP520ModuleInit "Mod1", "232", 0x81, 0, 1
# Init two IP520 modules from the 1st SBS VIPC616_01 carrier; the 1st
# module is in slot A, the 2nd module is in slot C.
IP520ModuleInit "Mod2", "232", 0x82, 1, 0
IP520ModuleInit "Mod3", "232", 0x83, 1, 2
# Init two IP520 modules from the 2nd SBS VIPC616_01 carrier; the 1st
# module is in slot B, the second module is in slot D.
IP520ModuleInit "Mod4", "232", 0x84, 2, 1
IP520ModuleInit "Mod5", "232", 0x85, 2, 3
# Create tty devices.
# ------------------
# IP520DevCreate(char *portname, int moduleID, int port#, int rdBufSize,
# int wrtBufSize)
# portname - assign the port a name for future reference.
# moduleID - moduleID from the IP520ModuleInit() call.
# port# - port number for this module [0-7].
# rdBufSize - read buffer size, in bytes.
# wrtBufSize - write buffer size, in bytes.
# Create two tty ports on Mod0 with <i>portname</i> based on the convention;
# "/tyGS/<i>carrier#,slot#</i>/<i>moduleID</i>/port#".
IP520DevCreate "/tyGS/0,0/0", "Mod0", 0, 512, 512
IP520DevCreate "/tyGS/0,0/1", "Mod0", 1, 512, 512
# Initialze all the remaining uninitialized Mod0 ports; i.e., /tyGS0/0/[2-7].
IP520DevCreateAll "/tyGS/0,0/", "Mod0", 512, 512
# Initialize all the Mod1 ports.
IP520DevCreateAll "/tyGS/0,1/", "Mod1", 512, 512
# Initialize all the Mod2 ports.
IP520DevCreateAll "/tyGS/1,0/", "Mod2", 512, 512
# Configure the ports.
# --------------------
# void IP520Config (char *portname, int baud, char parity, int stop,
# int bits, char flow)
# portname - portname from either the IP520DevCreate() call or
# the IP520DevCreateAll() call.
# baud - baudrate; 1200,2400,4800,9600,19200,38400,57600,115200,230400.
# parity - even - 'E', odd - 'O', or none - 'N'.
# stop - stop bits; 1 or 2.
# bits - data bits; 5,6,7 or 8.
# flow - flow control; hardware - 'H' or none - 'N'.
IP520Config "/tyGS/0,0/0", 38400, 'N', 1, 8, 'N'
# Ports default to 9600, 'N', 1, 8, 'N'
